Our company is certified in acc. with DIN EN ISO 9001:2015. To monitor our own production as well as for testing customer products, we have continuously expanded our state-of-the-art laboratory with connected measuring chamber.
Different material testing cabinets/climatic test cabinets are available for short-time corrosion tests. We can test all standard DIN requirements demanded in galvanization technology in our facilities.
Various electrolytes are tested daily for their process capability in our in-house laboratory.
This quick internal monitoring allows us to always present correctly set electrolytes and thus produce quality-conform products.
In addition, daily wastewater samples are recorded by means of photometric analyses which guarantees environmentally-conform discharging.
The corrosion resistance of a layer or a layer system is the essential characteristic. The layer thickness, the porosity and the chemical properties of the coating material largely determine the corrosion resistance. This can be tested with so-called short-time corrosion tests.
In these tests, the workpieces to be tested are subjected to a corrosive atmosphere for a few days, which corresponds to several years in a normal atmosphere. The white and red rust formation within a certain number of hours serves to determine the corrosion resistance.
The following short-time corrosion tests are available in our company:
- DIN 50017 (in condensation water climates)
- DIN 50018 (Kesternich test)
- DIN 50021-SS (salt spray testing)
- DIN EN ISO 4541 (Corrodkote test)
Layer thickness measuring
There are numerous, physically quite different methods for measuring the layer thickness. The application field of the different methods mainly depends on the layer and basic material as well as on the layer thickness itself.
We offer the following methods:
- DIN EN ISO 2178 magnetic inductive method (non-destructive)
- DIN EN ISO 3497 X-Ray fluorescence method (non-destructive)
- DIN EN ISO 2177 coulometric method (destructive)
Hardness is the resistance of a texture against the penetration of a harder test body.
We offer the following method:
- DIN EN ISO 6507 Vickers hardness test
Rough spots on surfaces are levelled during galvanisation while largely maintaining the geometrical shape. We mainly perform roughness measuring on hard chrome plated workpieces.
The following roughness values can be determined:
- Rz DIN 4768
- Rmax DIN 4768
- Ra DIN 4762
Environmental policy & wastewater treatment
The responsibility for environmental protection starts with the management. It defines the environmental policy and actively supports its observance to achieve sustained development. For surface finishing, environmental protection mainly means to detoxify hazardous wastewater from the electroplating shop to such an extent that the plant and animal life in natural bodies of water is not harmed in any way.
In our company, the wastewater (separated into different types) is subjected to a large internal continuous detoxification in treatment basins. The different types of wastewater are detoxified and neutralised with the corresponding chemicals. Afterwards, the suspended particles are removed in baffle plate thickeners. Then the cleaned water is discharged to the public sluice network.
Our aims are:
- To place as much importance on environmental protection like on the economic and social interests of the company.
- To return recyclings to the material cycles inasmuch as this is possible and economically feasible.
- To promote the sense of responsibility for the environment among our employees on all levels.
- To take the necessary measures in order to prevent accidental substance or energy emissions.
- The implementation of all specifications of our management system ensures that all operative activities that may have an impact on the environment are planned, controlled and monitored in order to meet the requirements.
- With the corresponding technical and organisational measures, we try to reduce the waste and recyclings quantities, environmentally harmful emissions and wastewater to a minimum.
