You want to harden and temper razor blades, scalpel blades, carpet knife blades or other metallic blade strips? We supply turnkey furnace plants for continuous hardening and tempering of blade strips.
With our experience of more than 120 years of industrial furnace construction and more than 160 realized units worldwide, we are the market leader for furnace plants for hardening and tempering blade strip material.
You want to harden and temper special strips, e.g. punched strips, shaver foils or other thin metal strips?
We will find a solution for you! Please contact us.
The hardening and tempering of blade strips consists of hardening and subsequent one-time tempering.
The crystal structure of the blade strip is transformed.
In the following, this will be explained briefly and in a very simplified way using the example of martensitic stainless steel.
Our furnaces for continuous hardening and tempering of blade strips are of modular design and designed for continuous operation. Through the sensible selection of standardised plant components, we configure the plant according to your requirements.
We will be pleased to consider your special requirements beyond our standards.
