Heat treatment, coating, joining

Because our customers always expect a special gearbox to be optimised for their application, we are pushed to the technical limits. State-of-the-art hardening processes, different materials, different alloys for casting the housings, new approaches to surface treatment or joining technology are constantly opening up new possibilities for us - together with our long-standing partners - to push these limits.

Heat and surface treatments

• Case hardening
• Induction hardening
• Nitrogen hardening / Oxidizing treatment
• Nitrocarburizing
• Boriding
• Electron beam hardening
• Phosphating
• Passivation
• Shot peening / Chemically supported slide grinding (C.A.S.E.^®)
• Surface coatings such as Balinit^®, Hart-coat^®, ceramic coating for sealing ring contact surfaces

Joining technologies

• Electron beam welding /laser welding
• Friction welding
• Shrink fits
• High-strength adhesive joints
