Process-specific products

We are often able to assist our customers using our core products, however, new materials and alloys, which have modified characteristics, are developed on a regular basis. Due to the fact that these parts also need to undergo intermediate and final cleaning, we have come to specialise in the development of process-specific products and solutions. Sustainability is of paramount importance during this development work.

Even if your components or assemblies are contaminated in an undefinable manner, we look for customised solutions that will enable us to clean, decoat, protect or maintain your components in a flawless manner.

We take a committed and creative approach to new challenges. No matter what kind of surface issue you are looking to resolve, we will come up with a specific, customised solution for you. Get in touch with us!


Quality management

Having a professional quality management system is very important to us as it underpins all of our activities. We can only ensure that our customers are 100% satisfied if we can guarantee that the quality of our products and services remains consistent.

With this in mind, we have clearly defined our standards and expectations: Consistent monitoring, extensive testing and predefined procedures enable us to uphold our standards, meet our expectations and provide you with the quality you require.

That being said, we are forever analysing our performances in a self-critical manner to ensure that our products and services are constantly improving. This allows us to remain flexible and dynamic and prevents us from resting on our laurels.
