Challenge & Goal
The forming and stamping of non-ferrous metals such as aluminum results in high tribological loads. Aluminum has a strong tendency to adhere to the tool surfaces (material build-up), which leads to increased friction, tool wear and uneven component quality.
Our solution
Our super-hard DLC coatings combine exceptional hardness with non-stick properties. This effectively prevents aluminum from sticking, the tool surface remains functional for longer and process stability increases.
Other non-ferrous metals that can be machined well include copper, brass and various steels, depending on the process temperature during machining.
Advantages for the customer
- Avoidance of material build-up and cold welding
- Significantly longer tool life when forming non-ferrous metals such as aluminum, copper or brass
- Consistent component quality and lower reject rates
- Less tool reworking and cleaning
- Lower process costs
