Our sustainibilty goals

The concept of sustainability for us is based on the three pillars of ecology, economy, and social responsibility. Only by aligning with the environment and our employees we can achieve long-term success. We continuously work towards the progress of various goals and measures in all three areas.

Our key sustainability goals are:

Reducing CO2 emissions to achieve climate neutrality (Scope 1, 2, 3)
Avoiding energy consumption (electricity, gas, heat)
Decreasing water usage
Substituting natural gas as an energy source
Optimizing raw material recycling towards a circular economy
Continuously expanding energy and environmental monitoring
Ensuring demand-oriented training across all departments
Promoting diversity and openness within the company
Responsible supply chains: Involving suppliers

Advantages of zinc die casting

Sustainable, long-lasting, economical

Zinc is a naturally occurring raw material that can be recycled indefinitely without compromising quality. In waste processing, it can be easily sorted and reintroduced into the circular economy.
Zinc die casting tools have a long service life and can be fully recycled at the end of their lifespan.
Very precise die casting reduces the effort required for mechanical processing.
Realization of thin-walled parts > low material usage and reduced weight
Good tensile and elongation strength, good impact and corrosion resistance > long service life of products
Functional integration can eliminate individual components or make additional steps obsolete (e.g. possible by realizing rivet domes or screw domes for self-tapping screws).
Zinc is highly machinable.
Significantly less sensitive to temperature and more dimensionally stable than plastic parts.
Compared to other manufacturing processes, zinc die casting offers a high output per hour, making it more cost-effective and sustainable.
Zinc is very easy to coat and thus offers a variety of high-quality decorative applications.
Even with lower production volumes, the production of die casting components can be economical and sustainable: If the geometry is milled from the solid blank, high mechanical production capacities and a lot of material are required. By constructively designing product families, many different variants can be produced from a cast blank through mechanical processing.
