Special Steels are used for making all kinds of mould such as hot work tool steel for aluminum extrusion, die-casting; cold work tool steel for blanking and punching tools, shear blades, automobile industry and electronic appliances; high speed steel for end mill cutter, twist drills, wood-working tool; plastic mould steel for PVC pipe, melamine kitchenware, screw part in the plastic injection machine. Since 1985, the company has been the sole distributor for “Bohler International GmbH” Austria who is one of the world’s largest and most highly regarded manufacturers. Tool steel imported by the company has therefore found a ready market with local customers on a continuous basis. The company provides a fully integrated cutting service,vertical and horizontal milling as well as surface grinding for making finishing plate for mould and dies,and also heat treatment service.
