Our service
Vacuum hardening is currently the most modern state-of-the-art in heat treatment technology. As no oxidation takes place in a vacuum environment, clean and clear surfaces are produced. High dimensional stability and low deformation are achieved through correct process parameters, intelligent loading and cooling systems with targeted nitrogen-dust deterrence. For requirements for very high dimensional stability, we can also offer deep cooling in a regulated deep cooling chamber. Our vacuum hardening plants have large capacities and furnaces of different sizes and thus high flexibility in hardening and tempering. With a maximum charge weight of 4,500 kg and a cooling gas pressure of up to 13 bar, even large tools, such as injection moulds, can be hardened. Equally important for optimum heat treatment results are the know-how and many years of experience of our experts, who supervise their tools during the entire heat treatment process. All heat treatment parameters are precisely and completely documented by the process-controlled vacuum furnaces. This ensures that every heat treatment process is always reproducible, so that exactly the same parameters can be set for your tools again and again. Our quality standards are high and continuously monitored.
We are DIN EN ISO 9001:2008 certified and comply with NADCAP standards.
Own delivery service
Thanks to our own delivery service, we collect the tools from you if you wish, and also return them to you after optimum heat treatment.
Delivery times are 3 – 7 working days. Express orders are possible by prior arrangement.
