FAQ

We have set our focus on the development, planning and production of cleaning systems. In the process, we take a close look at each of our customers’ tasks in order to find a suitable solution. Solubility of dirt, part geometry, cleanliness requirements, output rate are exactly matched to the customer application. In addition to plant engineering and construction, we offer the appropriate cleaning chemicals and contract cleaning.

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.
In the future a cleaning service for our customers in Hungary will be established.

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.

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.

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.

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.

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.
