Mold which is widely used in blanking, die forging, cold heading, extrusion, pressing of powder metallurgy parts, pressure casting, plastic or injection molding of engineering plastics, rubber, ceramics and other products is a tool used to make shaped objects, and is known as the "mother of industry". Die materials play an important role to meet the requirements of the mold strength, stiffness, hardness, roughness, precision, wear resistance, resistance to deformation, high temperature resistance, resistance to melt loss and long life. Gina provides long service life of die steel materials by vacuum refining patent technology, solidification technology, IESR re-melt technology and material chemical design.
