Cleaning/preservation
With our modern, PER- and alkaline-based facilities and ultrasonic cleaning system, we can perform chemical surface pretreatments such as cleaning, degreasing, and preservation. We have a wide range of washing programs available for product-compatible cleaning, thus also meeting the elevated requirements of the automotive sector.
We use two different automatic washing systems for cleaning and preservation:
Alkaline washing systems
For cleaning and degreasing magnesium components with alkaline washing solution.
Perchlorethylene washing system
For cleaning and degreasing with perchlorethylene with part-specific washing programs, ultrasonic function, and preservation.
Surface treatment
In addition to mechanical surface treatment for interfacial interaction such as grinding, polishing, and shot peening, we also offer various types of surface coating such as painting, powder coating, or chrome plating. Depending on the process, results such as mechanical protection (wear, friction), a barrier function (corrosion resistance, thermal insulation), an electrical function (conductivity, electrical insulation), or an optical function (reflection, decoration) can be achieved.
Heat treatment
We supply you with components ready for installation, including heat treatment processes such as hardening, tempering, and annealing.
Hardening
Hardening takes place in three stages: heating up to hardening temperature, staying at this temperature level for a short time, and quenching. Structural steels, which require high strength and stability, are quenched and tempered.
Tempering
Tempering, which is reheating to temperatures between 200 and 350 °C after hardening, reduces internal stresses and the brittleness caused by hardening, thus increasing stability. However, this is only possible at the expense of hardness.
Annealing
Structural steels, which need both high strength and stability, are quenched and tempered. Examples include screws, chocks, tappets, and shafts. Annealing is a hardening process followed by high tempering to temperatures between 550 and 700 °C. This produces a fine-grained material structure with very high strength values.
