Using nano-sized particle carbon tungsten powder, which has high corrosion and wear resistance and is difficult to oxidize.
The "SPS Super Hardening Series" is a new super hard material created by adding a unique sintering process to carefully selected nano-sized carbon tungsten (WC) powder. It combines hardness and strength that surpass traditional cemented carbides, making it suitable for various usage environments. Since it uses only the world's smallest class of fine WC powder, its hardness ranks among the top in super hard materials. It excels in corrosion and wear resistance and is less prone to oxidation, allowing for high mirror precision to be maintained over time. 【Features】 ■ Excellent wear resistance → Uses only the world's smallest class of fine WC powder ■ Excellent heat resistance → Does not contain cobalt, which has a low melting point, making it less prone to thermal expansion, melting, or plastic deformation, suitable for processing at high temperatures ■ Achieves no-binder hardening → Adopts a domestically produced discharge plasma sintering method → Rapid heating due to self-heating allows for meticulous sintering while preserving the material's characteristics For more details, please contact us or download the catalog.

Company information
In September 1991, PMT Corporation was founded as a general trading company for semiconductor manufacturing equipment. Since then, after processing parts and designing and manufacturing molds, we established ultra-precision axis control technology. We have leveraged this as our strength and applied it to various machines and devices, including the nano-stage system, NC fine processing machines, and maskless exposure devices. Currently, we are also engaged in automation systems specialized for the life sciences sector and robotics projects that solve challenges in manufacturing sites, continuing to create products that transcend industry boundaries. Our motto is, "What shall we create with PMT?" Please let us know your requests first.
