Surface modification nitriding treatment "Sem Plasma Nitriding"

Improving the lifespan of molds and enhancing the wear resistance of machine parts! – Even for complex-shaped components, there is no nitride unevenness and quality is stable. *Free prototypes available.

This is a surface hardening method that generates glow discharge in a dilute mixed gas atmosphere of nitrogen and hydrogen at several hundred pascals, simultaneously heating the workpiece and promoting nitriding due to ion impacts. Plasma nitriding is a processing method that is completely different from conventional nitriding methods, and it is currently being widely used for various mechanical parts, precision components, injection molding machine parts, and various molds, including automotive parts. In particular, our equipment features a built-in heater that allows for separate control of nitriding temperature and discharge conditions, making it a groundbreaking system that ensures uniform and excellent quality even in large capacity processing and large part treatment. - Features of Plasma Nitriding - (1) Nitriding can be performed only on the necessary parts (ensuring reliable anti-nitriding) (2) Minimal thermal distortion (3) A tough compound layer is obtained (4) It is the cleanest manufacturing method.
