Latest hardening plant technology and long-lasting service
The hardening plant was completely renovated between 2016 and 2018 and now boasts the latest heat treatment technologies for use in various heat treatment processes.
The modern plant makes it possible to produce oxidation-free surfaces, eliminates retained austenite and enables uniform low-pressure carburizing.
Alongside the process optimization, these new developments also play a role in sustainably maximizing the service life of components.
Our contract hardening plant is available to all customers from the hardening technology, surface technology and material analysis sectors.

Processes
As a full-service provider we can offer the complete heat treatment processes form a single source.
Hybrid cleaning is an alkaline/alcoholic ultrasonic cleaning process with maximum cleaning power. Three cleaning methods are possible: Swivel cleaning, spray cleaning and air purification.
Other benefits:
- Vacuum drying of components after cleaning
- Regular concentration measurements of the cleaning medium in our internal chemistry department
In contrast to conventional carburizing, low-pressure pulsed carburizing prevents surface oxidation which would go on to cause component failure. This new technology therefore extends the service life of components.
Other benefits:
- The carbon transfer rate is very high
- Extremely uniform carburizing even with complex geometries
- Excellent cost-effectiveness thanks to minimal gas consumption
- Short process times thanks to high carburizing temperatures
Vacuum hardening with high-pressure gas quenching takes place at a nitrogen pressure of up to 20 bar and prevents surface oxidation.
Other benefits:
- Single-chamber furnace with reversing cooling
- Two-chamber furnace with cold chamber
The deep-freeze furnace is able to cover a temperature range from -120 °C to 600 °C. This makes deep-freezing with subsequent tempering possible without needing to change furnace.
Other benefits:
- The deep-freezing process minimizes the retained austenite content in the component
- No corrosion on the components
Gas nitriding with nitriding potential control is adapted to the furnace load.
Other benefits:
- The furnace systems have an oxygen probe to precisely monitor the pre-oxidation and post-oxidation processes
- External rapid cooling at the furnace systems speeds up the cooling process and reduces the process times
- Controlled gas nitrocarburizing is possible
