Cemented carbide molds are precision molds made with tungsten carbide powder as the main component and cobalt as the binder phase through powder metallurgy process. Their inner surface mirror roughness is generally around 0.1μm. CTIA GROUP LTD cemented carbide molds are widely used in various cold and hot forming processes such as cold heading, cold extrusion, cold punching, wire drawing, powder metallurgy pressing, and hot forging dies.
