Due to the wide range of uses of the mold, a variety of mold working conditions vary greatly, so, the manufacture of mold materials with a wide range of materials, in the mold materials are widely used when the mold steel. From general carbon structural steel, carbon tool steel, alloy structural steel, alloy tool steel, spring steel, high-speed tool steel, stainless heat-resistant steel until the need to adapt to the special mold maraging steel and powder high-speed steel, powder high-alloy die steel, etc. Mould steel can be generally divided into three categories according to the use of cold work mold steel, hot work mold steel and plastic molding with mold steel.The next mold steel supplier will introduce the classification of mold steel.
Cold work tool steel is mainly used to make the cold state of the workpiece to press the mold. Such as: cold punching and cutting dies, cold stamping dies, cold drawing dies, embossing dies, cold extrusion dies, thread pressing dies and powder pressing dies, etc. The range of cold work die steel is very wide, . From various carbon tool steels, alloy tool steels, high speed tool steels to powder high speed tool steels and powder high alloy tool steels. Cold work tool steel is vacuum degassed and refined steel, the internal quality is pure, good machinability, cutting significantly improved, good hardenability, air-cooled hardening is not easy to appear hardening crack, wear resistance is extremely good, good toughness, can be used as stainless steel and high hardness material punching and cutting dies.
Hot work die steel is mainly used for the manufacture of high temperature state of the workpiece pressure processing of the die. Such as: hot forging dies, hot extrusion dies, die-casting dies, hot forging dies, etc.. Commonly used hot work die steel are: high carbon content added Cr, W, Mo, V and other alloying elements of alloy die steel; special requirements of hot work die steel, sometimes using high alloy austenite heat-resistant die steel manufacturing.
Because of the many varieties of plastic, plastic products requirements are also very different, the manufacture of plastic mold materials also put forward a variety of different performance requirements. Therefore, many industrial countries have formed a wide range of plastic mold with steel series. Including carbon structural steel, carburizing plastic mold steel, pre-hardening plastic mold steel, age-hardening plastic mold steel, corrosion-resistant plastic mold steel, easy to cut plastic mold steel, overall hardening plastic mold steel, maraging steel and mirror polishing with plastic mold steel, etc.
Risunsteel, based on the over one hundred years'production history of special steel in Huangshi, provide professional services and material for cutting tool companies, mould companies and other industrial enterprises all over the world for years.
