We currently employ 46 people.

We are active in the field of industrial parts cleaning.
Since our foundation in 1995, we have been intensively involved in the cleaning of parts with various geometries made of almost any material. The size of the components is not decisive. Whether it’s the ultra-fine cleaning of precision parts or degreasing in a mesh box, we will find the ideal process.

Already in 2009 we started to give young people the opportunity to do an apprenticeship at vapic. At that time we only trained mechatronics engineers, in the meantime the professions technical product designer and construction mechanic have been added. Currently we employ 6 trainees.

For solvents, whether hydrocarbon, modified alcohol or perchloroethylene, we offer all techniques. Conceivable are both spray cleaning and immersion cleaning systems. Furthermore, we have often implemented combined systems with a full aqueous cleaning.
We have developed different process steps to meet particularly high cleanliness requirements with a low energy input.
In addition to solvents, we also offer you the other substances required, such as stabilisers to maintain the pH value.

Vapic has a location in 75387 Neubulach in the Black Forest.
Our construction department, the administration, the plant construction, the parts cleaning centre is located here,
the development and production of the cleaning agents and our laboratory.
We also have a subsidiary, vapic Hungary Kft., which is located in 6116 Fülöpjakab in Hungary. This company produces components of the highest quality for our main factory.

We use different suppliers for the transport of our goods and products and do not have our own transport fleet.

The difference between the two methods is that in spray cleaning, the cleaning medium is sprayed with pressure from different nozzles. In immersion cleaning, on the other hand, the component is completely covered in a so-called working chamber. Depending on the project and, for example, geometry and cleanliness requirements, the appropriate process is determined.

For solvents, whether hydrocarbon, modified alcohol or perchloroethylene, we offer all techniques. Conceivable are both spray cleaning and immersion cleaning systems. Furthermore, we have often implemented combined systems with a full aqueous cleaning.
We have developed different process steps to meet particularly high cleanliness requirements with a low energy input.
In addition to solvents, we also offer you the other substances required, such as stabilisers to maintain the pH value.

If you decide in favour of us as your plant and chemical supplier, we offer you the so-called process guarantee. We ensure that your components achieve the desired cleanliness and support you in bath care and plant maintenance. Your great advantage is that you have only one contact person and in case of problems the other party is not blamed.
We see ourselves as “caretakers” and support you as quickly as possible to ensure that your process runs smoothly.
Due to our understanding in both areas we can help you effectively.

Pre-Wash means pre-cleaning. Under our “Pre-Wash” option, we pre-clean a large amount of dirt without contaminating the tank. Due to a separate circuit with filter, pump and piping, there is less mixing in the cleaning tanks. A permanently higher quality of the cleaning tanks ensures effective cleaning.

The word CNp was introduced by one of our market companions in the field of aqueous chamber cleaning systems. This is a cleaning process in the flooded state of a chamber system in a vacuum. The principle works on basic physical properties by shifting the boiling point. By creating a deep vacuum, the boiling point of the cleaning medium is lowered. Steam bubbles are formed in narrow undercuts, bores and blind holes Ø > 6mm.
By increasing the pressure again, the boiling point shifts to a higher temperature and the steam bubbles implode. This results in an exchange of medium in places that would otherwise not be reached by capillary action. We have been using this process technology of the process step since 2003 to clean components with complex geometries efficiently and reliably. You will find this with us under the term “alternating pressure”. In doing so, we realize the implementation in an energy-saving and economical way. We will be happy to answer any questions you may have about this and the differences in implementation.

Alternating pressure in the working chamber shifts the boiling point to make the cleaning agent oscillate between boiling and condensation. This method is proven to amplify the rinsing effect, in particular in small blind holes(Ø < 6 mm) since the fluid forms vapour bubbles at low pressure that implode in turn as pressure increases. This ensures a powerful cleaning agent exchange even in more complicated component geometries. Alternating pressure can be used with solvents and with rinsing baths for aqueous cleaners alike. In the case of vapic, the heat of condensation is recovered.

Probably the biggest advantage of our Modular in-line plant is that a very short cycle time
is possible for parts with a high level of technical cleanliness. Due to the modular design, the machine can be easily extended at any time, so that if the task is changed
in future, it will not be necessary to make a completely new investment for a car wash.
Numerous customers are already using this type of system and the response is very good.

We offer all processes in the field of liquid chemical cleaning.
From simple ultrasonic baths, spraying systems to vacuum systems with fully automatic loading by means of shuttle vehicles, we offer you the appropriate solution. We are also experienced in the chemical industry with solvents such as PER, hydrocarbon or modified alcohols as well as aqueous cleaners.
Due to our unique cleaning processes and our energy-saving technology, we offer you process-safe cleaning at the best possible price.

Chamber systems are one of many types of cleaning machines used in industrial parts cleaning. The name has established itself in the industry as the entire cleaning process as well as the drying process takes place in one chamber.

Some benefits of our chamber cleaning machines are:
Vacuum drying, energy-saving process engineering, good material movement, special cleaning processes.

We also customize our chamber systems for cleaning your components and design them in the required size and equipment.

The vapic process is characterized by an enormous energy saving compared to the techniques of our competitors. By using dry-running vacuum pumps, we use the compression and condensation energy so that it is not being lost. We usually save more than 50% energy compared to other cleaning systems. In addition to the low operating costs, you also benefit from the possibility of claiming subsidies when you invest in one of our machines.

In order to carry out preliminary tests in our company, we have various ultrasonic basins, spraying systems and baths. Also we can use our machinery for contract cleaning. You can find our machines here: https://www.vapic.de/en/parts-cleaning-centre/machinery/
We also have possibilities for preliminary tests in the field of dry cleaning.

We can offer almost any machine, as we are a special machine manufacturer.
From ultrasonic baths, spray and immersion cleaning equipment to machines for paint and resin removal. We also offer the right solution for the drying of various components. Here we offer vacuum drying, vacuum infrared drying, hot air drying, heat pump drying and induction drying.

Occasionally we also have used washing machines from market companions for sale. But also here we only offer you the machine if our advice is that it is suitable for your task. Our aim is not necessarily to sell a machine, but to offer you the best solution.

Due to our systems at customers’ sites as well as the cleaning of customer parts on a subcontract basis, we have acquired a great deal of know-how in the cleaning of components from various manufacturing processes. From precision parts such as turned parts, milled parts, punched parts, formed parts to chrome-plated parts, we have already mapped almost all processes. The components are used in a wide range of industries such as the automotive sector, electronics, household appliances, air technology and machinery. From safety technology in cars to fittings and razor blades in bathrooms. Parts that have been washed by us can be found in many areas.

Continuous cleaning systems are machines for cleaning different components made of metal, plastic or other materials. The components pass through various cleaning, rinsing, neutral and drying zones. Due to the design a high throughput is possible. If required, we can usually offer a goods movement system so that all sections of the parts become clean. In most cases, continuous washing systems are linked to other machines in production lines. Condensation dryers are an option with us. In this way we reduce your operating costs and protect the environment. The parts temperature during unloading is also much colder than with hot air drying.

Service and customer satisfaction is our top priority. Of course, we also support you after the sale of the appropriate cleaning system in every respect. We offer you all spare parts for the cleaning system at fair prices and invoice our service calls on a time and material basis. In order to be able to react as quickly as possible, our systems also have a very good remote maintenance system. Here too, we are glad to help you with any problems. In the field of bath care we offer to examine your samples regularly in our laboratory.
You will then receive a detailed report with suggestions for measures to be taken.

The aim of processing solvents such as hydrocarbons, modified alcohols and chlorinated hydrocarbons is to keep them as pure as possible.
The treatment removes impurities from the solvent.
It is also important that the treatment process is ideally suited to the respective substances. At vapic we have the appropriate treatment processes for all common solvents and are pleased to offer them to you.

Due to our unique vacuum distillers in the solvent range, no complete exchange of the solvent is necessary. An integrated plant distillation system ensures that the solvent is permanently prepared and the tanks of the cleaning plant are kept clean. If a particularly large amount of oil is introduced into the washing system, it is also advisable to integrate an additional vacuum distiller in the bypass. Due to the special process technology, we save at least 50% of the energy required to prepare the solvent for cleaning parts.

Continuous flow washing systems offer the advantage that a very large throughput of components can be cleaned. Due to the design with a continuous conveyor system, handling is also very easy to realise. Often a lot of energy is needed in these plants, but we have found ways to optimise the plants. By saving energy, our continuous cleaning systems can also be subsidised by the state. So you save twice, in investment and in operating costs.

The design of the Modular in-line system developed by us is highly variable. Since we are active as a special plant manufacturer, we can optimally adapt the machines to your requirements. The nice thing about our Modular cleaning system is that it can be expanded quickly and cost-effectively. The machine can be ideally adapted to your precision components by means of various modules such as tub modules with ultrasonic or chamber modules with several tanks or vacuum. A further advantage compared to conventional systems is that carry-over is minimised. We only transport the goods carrier between the individual modules. Even a connection in the clean room is no problem. Each module is an almost independent machine with control, handling and filtration. This keeps the complex machines manageable.

To keep aqueous parts cleaning systems clean, we use various treatment processes. Depending on the properties of the lubricants these are: Centrifugal tanks, centrifuges, filters of all types, oil separators, sediment separators, creeping bath renewal, evaporators with vapour technology and ultrafiltration systems.
In order to define which technology is suitable, we would be pleased to examine your lubricants in our laboratory.

We have been carrying out residual dirt analyses in clean rooms for over 10 years. Already in 2011, our head of cleanliness analyses Daniela Wolf completed her examination to become “Examiner for Technical Cleanliness” at the Fraunhofer Institute in Stuttgart. She gained knowledge about the basics of the extration and analysis methods, cleanliness-compatible behaviour and much more. She carries out cleanliness analyses in accordance with VDA Volume 19 both as a service and in the parts cleaning centre. We offer you particle analyses at fair prices with detailed documentation including photos. Due to our many years of experience, we can support you if you do not have any specifications for carrying out the analysis.

Of course, various control procedures are possible after the cleaning of customer components in our contract cleaning. If the customer has particle requirements, we can carry out in-process residual dirt analyses according to VDA Volume 19 and customer standards. In case of surface cleanliness requirements, we offer to determine the surface tension by means of test inks. We also have components in our contract cleaning department where we carry out a 100% visual inspection. How your components will be checked, we determine together before the order.

The parts washed by us on a contract basis are always packed according to the customer’s requirements. Depending on the requirements, they are packed in bags, sealed bags, VCI bags, etc. Smallest parts can be packed exactly to the piece by exact weighing. Parts with high technical cleanliness requirements are packed in a clean room.

Of course we can also carry out ultra-fine cleaning. We would be pleased to offer you contract cleaning or a suitable machine for your products. Due to the latest process engineering and innovative cleaning processes we are sure that our machines will convince you.

For quality control in industrial component cleaning, we also use residual dirt analyses for particulate contamination. Depending on the requirements, we comply with VDA Band 19 (ISO 16232) and customer standards. In addition to process-accompanying cleanliness analyses of components that we have washed in our contract cleaning, we also carry out analyses of customer parts as a service. Thanks to our many years of experience with a wide variety of metal and plastic parts, we are also happy to be able to assist you in determining the individual parameters such as the volume flow and the flushing quantity of the extrusion fluid.

For the degreasing of various production parts vapic has several cleaning machines at its disposal. Depending on technical cleanliness requirements and the properties of the processing oil, we offer cleaning with hydrocarbon, modified alcohol and perchloroethylene (PER). The choice of machine also depends on the quantity, size and material of the components to be cleaned. We would be pleased to check for you which machine is best suited for your specific parts.

Many different factors have to be taken into account for fine cleaning. First, the cleaner must match the contamination in order to dissolve the corresponding lubricant, such as a forming oil or a cooling lubricant. The cleaning process must also be adapted by treatment times, temperatures, cleaning methods and other options. Depending on the component geometry, a certain position in the product carrier must also be considered. During operation, it is also important to ensure that the bath preparation is functioning properly, otherwise quality problems can occur during component cleaning.

There is no clear definition in the parts cleaning industry between fine cleaning and ultra-fine cleaning. At vapic we define the difference by the component geometry, the cleaning and packaging process and the required cleanliness of the parts. As a result of our new clean room, built in 2020, with an area of over 100 m², we are also equipped for parts with high demands on technical cleanliness. Especially with very high requirements it is absolutely necessary to have a lot of knowledge in this area. That is why many of our customers also use our contract cleaning service for very difficult components, for example. By means of process-accompanying inspections with test inks, residual dirt analyses and optical controls, we determine the required cleanliness after the cleaning system.

In our cleanliness analysis laboratory we carry out residual dirt analyses in the field of parts cleaning according to VDA Volume 19, ISO 16232 or according to customer standards. We are also glad to help with our know-how on various components and component geometries. In the past, we have often specified analysis values for customers in order to determine the cleanliness after a cleaning test. We are also happy to offer you the best residual dirt analyses including a meaningful report as a service.

Of course we also offer visual inspections in our parts cleaning centre after the contract cleaning of your components. In doing so, we conscientiously and carefully check the cleanliness and possible deformations of very sensitive components. In order to be able to make the best possible assessment, we need a catalogue of defects from you, which is tailored to your components.

The technical cleanliness of parts is getting steadily more important.
This has the background that a clean surface or parts without particles are relevant for many systems. Often the subsequent processes such as assembly, heat treatment or joining processes require clean surfaces. Without the required cleanliness, a quality assured function cannot be guaranteed. Even the smallest particles can cause great damage in the field of safety engineering.

Aqueous cleaners are well suited to dissolve oils, fats and emulsions as well as salts, particles and other soiling. Due to our 2-component system, builders and surfactants can be dosed separately as required. As water is not flammable, there is no fire load.
We are pleased to evaluate which cleaner is best suited for your soiling in our standardized solubility test.

It is called degreasing when lubricants are to be removed from the surface. The technical drawings refer to the requirement “grease-free”. As grease-free is not clearly defined, we recommend that the requirements are always specified with a surface tension. However, these are not components in which particles play a decisive role. In our parts cleaning centre we have the possibility to degrease our customers’ parts in lattice boxes fully automatically at very good prices.

Cleaning with solvents is recommended if your components have oily soiling. The solvent is itself like a thin oil, in which the machining oils dissolve optimally and thus a very good degreasing
result is achieved. Through an integrated distillative treatment we obtain a constantly clean tank.

The superfine cleaning is required if your components to be cleaned have high technical cleanliness requirements. By using different cleaning processes and machines on which only pre-cleaned parts are washed, we achieve very good results.

In most cases, parts that are manufactured with an emulsion are cleaned in an aqueous system. However, if the remaining residues are oils that can be dissolved with solvents, cleaning in e.g. hydrocarbons is also possible. We will be glad to determine the suitable cleaning solution for you in our laboratory – since every lubricant is different, no general answer is possible here.

The advantage of immersion cleaning is that the entire component or components are in contact with the cleaner. This allows oils, greases and dirt particles to be dissolved very well. Immersion cleaning is also suitable for complex component geometries where spray cleaning would not reach all areas. Likewise, no damage from the spray pressure is to be expected for particularly difficult, sensitive parts.

A detailed consideration of the production process as well as the oils, cooling lubricant emulsions etc. used is also essential here. In addition to the good cleaning properties, you benefit from the fact that your cleaning medium is not flammable when cleaning your turned, stamped and deep-drawn parts, etc. By means of various treatment processes we ensure a constant washing quality and long service life. We also minimise the maintenance effort. We would be pleased to advise you personally on a project-related basis.
In most cases you cannot work with water alone, a suitable cleaning agent is necessary. If there are many requirements, several rinsing processes are necessary.

The advantages of a combined cleaning from aqueous cleaner and solvent is the wide range of dirt solubility. Both organic soiling such as oils and inorganic contamination such as salts from fingerprints can be removed. Through our process engineering, we also equip these washing systems in such a way that the input power is kept as low as possible.

Immersion cleaning is essential when washing components with complex geometries. Only in this way can it be guaranteed that the parts are completely clean. By using different cleaning methods, even blind holes, narrow gaps and small bores can be cleaned reliably.

Spray cleaning is particularly suitable for components with simple geometries where a high degree of mechanical action is required. Spray cleaning systems are often used to remove particulate contamination from parts.

Distillation is a process for treating solvents. In conventional, simple distillation, the sump with the solvent-oil mixture is heated with a suitable heat source. The solvent then passes from the liquid phase to the vapour phase due to its lower boiling point. The solvent is then condensed again by a cooler. At vapic we work with vapour compression in a vacuum, i.e. we work with several pressure ranges so that we keep the energy in the process. In this way we achieve a high energy saving.

In vacuum drying, the boiling point of the liquid to be evaporated is lowered by building up a vacuum. Due to the treatment of the part, it has an inherent heat. If the mass of the component is not sufficient, it will not dry out, which is why we integrate infrared radiators into our machines. By using infrared pulses, additional heat is introduced. This means that even parts with low mass and large surface area become dry.

In order to obtain consistent, stable results when washing finished parts, a good bath quality is necessary. Particles, fibres, emulsions, oils are separated from the bath by the bath preparation. This results in good and above all constant degrees of purity.

In order to maintain a constantly clean bath or tank, various treatment processes are used. Depending on the type of contamination introduced, our systems are equipped with filters, centrifuges, evaporators, gravity separators, ultrafiltration systems, stepwise bath renewal and much more. This makes it possible to permanently maintain quality requirements for particulate or film contamination with the lowest maintenance effort.

The terms refer to the pH value of the respective aqueous cleaners for parts cleaning. We speak of an acidic cleaner if the pH value of the cleaning solution is in the range of 0 – 5. At a pH value of 5 – 9 we speak of a neutral cleaner. Above pH 9 up to pH 11.5 the cleaning solution is alkaline. Often even highly alkaline cleaners are used to saponify oils from machining processes from the components. Here one is in a pH-value range of 11.5 – 14. Depending on the manufacturer of the cleaning chemicals the differentiation differs to a small extent. It is also important to remember that the pH value is a logarithmic value. It is defined by the -1 multiplied decadic logarithm (decimal logarithm) of the oxonium ion concentration (or oxonium ion activity). As a manufacturer of cleaning systems in the field of industrial component cleaning, we take great care to know the entire process and are therefore happy to offer this to our customers.

Under the term “Smart Heating” one of our market companions has registered a utility model and a patent. The machine is brought up to operating temperature at a defined point in time by means of a heating control of the washing system. As our systems have been equipped with a time switch for decades, we have not identified any need in this area. By means of empirical values and a mathematical calculation, we are able to set it in such a way that the machine does not require high energy consumption. By the way: Due to our innovative process technology, we are the only manufacturer of industrial parts cleaning systems to offer you the possibility of receiving subsidies for an investment. We would be pleased to advise you individually.

The surface energy of the part is checked as follows:
The corresponding parts are cleaned on a laboratory scale or in a part-washing plant. After cooling the parts to room temperature, the surface tension is determined in the unit mN/m by so-called test inks. Based on the determined value, statements can be made as to whether the manufactured parts are suitable for the subsequent process such as bonding, welding, hardening or a coating process. In addition to testing with test inks, many users also use contact angle measurements or fluorescence measurements.

In general, it must always be checked first whether the lubricants and contaminants on the manufactured parts can be dissolved in water. If this is the case and a solvent system is out of the question, aqueous cleaning is used. This means that the machine first cleans the parts with an aqueous cleaner. Here concentrates are used and then the rest is filled up with water. Afterwards the cleaner residues must be rinsed off by rinsing with city water or demineralised water. Advantages in this case are the solubility as well as often the low risk of fire load and ideally mild cleaning chemicals. Also the dispersion ability, i.e. the ability to dissolve fine solids better and to prevent them from being deposited on the component again, of the cleaning media is higher than with solvents. “Open systems” such as continuous flow systems and tubs are usually designed as aqueous systems.

The tasks of a cleaning system are to clean and dry parts that are contaminated with different types of dirt. Depending on the component and the application, the requirements are very different. In general, a distinction is made between solids as contamination, i.e. particulate and film contamination. Filmic contamination includes oils, greases, residues of cooling lubricant emulsions and other manufacturing aids. Whether the required technical cleanliness is achieved can be determined by various means such as test inks, residual dirt analyses, optical and also measuring technology.

In order to guarantee a constant cleanliness of the goods to be cleaned, it is very important to keep the baths or tanks of the cleaning system clean. The bath quality directly influences the degree of cleanliness of the parts. In order to prevent a saw-tooth effect in the degree of contamination, we use suitable treatment processes such as distillation / evaporation, filtration, ultrafiltration, gravity separators and many other processes in our cleaning systems for industrial component cleaning.

Oil and sediment separators are used in parts cleaning in the field of aqueous cleaning. They are used to separate oils / lubricants from the cleaning medium. In many cases, gravity can be used for this purpose, as several phases are formed due to the different physical properties such as density. Oil separators are particularly necessary in washing plants where a lot of oil is introduced by the components to be washed.

We offer a wide range of aqueous cleaners in the acid, neutral and alkaline range. We also supply various solvents such as hydrocarbons and modified alcohols. We complete our service with various additives such as our defoamer. Through standardised preliminary tests we can also determine for you in the laboratory which cleaning agent is best suited for your application. If we do not have a suitable cleaner in our portfolio, we will develop an adapted cleaning solution for you.

In our compatibility tests and process simulation procedures we check which reactions can be expected in a later cleaning system. They are part of our development of the appropriate parts cleaning system for you. If, for example, a distillery is to be integrated into this system for processing the solvents, we check whether acids or solids are formed. In a defined way we prevent various problems with our auxiliary materials. Thus the process for parts cleaning starts reliably.

In our preliminary tests we determine which cleaner is best suited to each of your lubricants. By means of standardised tests in our so-called “solubility test”, we check various parameters such as phase separation, foam formation and performance, i.e. the cleaning performance of the cleaning medium used. We also carefully check the safety data sheets to determine possible long-term effects. This workflow has already enabled us to offer our customers numerous successful solutions.

We offer a very wide range of different solvents and solvent mixtures. By selecting according to their properties, such as polarity and flash point, we have the ideal solvent for most soiling, which we can check with laboratory tests and, if necessary, optimise by adapting the formulation to your application. We only use raw materials of the highest quality and due to our many years of experience, the performance, i.e. the cleaning efficiency, is very good. A further advantage is that our solvents can be reprocessed by distillation. No matter whether you need a hydrocarbon, a modified alcohol or any other solvent – you have come to the right place.
4.)

Depending on the application, various auxiliary materials are required to ensure stable, process-reliable cleaning. A special vacuum pump oil is required for the operation of our standard dry-running vacuum pumps.
If too much foam is produced in the chamber of an aqueous cleaning system, a defoamer must be added, otherwise problems with the level sensors or cleanliness may occur. If acids are formed, the cleaning contents of the machine must be brought back into the correct pH range with alkaline stabilizers. There are various applications where an additive is absolutely necessary and very helpful.

As cleaning agents we call all cleaning components which are used in the cleaning technology. This includes solvents such as: hydrocarbon, modified alcohol and PER (perchloroethylene) but also aqueous cleaners in the acid, neutral, alkaline and highly alkaline range.
