Gas Nitriding

Our gas nitriding process enhances material surface properties, suitable for dies and molds making industries. Also can be used for die casting dies where they need a thin but hard layer. The machine diffuses nitrogen ion between base metal matrixes to form a hard layer of carbide of 1000 – 1200 HV, nitriding layer depth ranging from 50 – 200 micron and compound layer thickness ranging from less than 1 micron to 12 micron.

Furnace size : 600 x 600 x 900 mm or approximately 500 kg.

TD Process

Surface treatment is to further enhance die and mold surface properties, to prolong the die and mold life time in a severer production process.

To improve surface properties for cold working dies, we have TD Process service. A superior hard layer of VC (Vanadium Carbide) diffuses into material surface, forming a 5 – 10 micron layer, improving its wear resistant properties significantly as the layer hardness is 3000 -3500 HV (equal to 200 HRC).

Furnace size : φ 420 x 400 mm

Suitable for cold work dies or material with carbon content 0,3 % or more and hardening temperature minimum 1030°C.
