Plastic mold steel is widely used in industry and daily life. The raw materials of our common molds, scissors, mechanical parts, TV casings, refrigerator inner casings, etc. are plastic mold steel. Many customers of our Songshun Steel will repurchase several cabinets of plastic mold steel every year. There are many types and applications of plastic mold steel, so we will look at the products that customers need to apply, and then recommend the most suitable products to customers. with the best price.
Different types of plastic mold steel have different application fields and products, so it is necessary to understand plastic mold steel clearly in order to find the steel that is suitable for your company.
AISI P20 steel has many excellent properties. It has been pre hardened to 285-330HB (30-36HRC), which is equivalent to the GS-2311 state of Sweden 618 and Germany. It can be directly used for die making and processing, and has the characteristics of good dimensional stability. Only the pre hardened steel can meet the needs of general use, and the service life of the die can reach 50W modules.
P20 steel can be applied to plastic molds and mold bases such as TV front shells, telephone sets, water dispensers, and vacuum cleaners. It can also be used to manufacture extrusion molds, refrigerator inner shells, and various buckets.
P20+S mold steel is equivalent to DIN 1.2312 steel. Because of its high S content, it has excellent cutting performance, good toughness, good wear resistance, uniform hardness of all dimensions, stable dimensions, and no heat treatment is required. 280-325HB is in the quenched and tempered state, which is suitable for nitriding treatment to increase wear resistance.
P20+S steel is widely used in formwork, zinc die-casting molds, back plates, backing plates and injection molds, etc.
AISI S136 mold steel is equivalent to DIN 1.2316 plastic mold steel. It has stable heat conduction properties and has excellent corrosion resistance, polishability, wear resistance, hardenability, machinability, toughness and ductility, etc.
It can be widely used in the production of optical products with high-smooth surfaces, such as cameras, sunglasses, chemical instruments, syringes, and plastic products, etc.
NAK80 steel is a kind of pre-hardened plastic mold steel. The steel is pure after vacuum degassing and refining. It does not need heat treatment. It has good polishing, welding and carving properties, and good discharge machining.
It is widely used in mirror polishing molds, anti-dust, TV filter plates, cosmetic boxes, precision wrinkle processing molds, office automation equipment, and auto parts electric discharge machining molds. Also used in various scissors, inlay blades, woodworking blades, thread rolling dies and wear slides, etc.
The above are just some of the most commonly used and repurchased steel materials by our Songshun steel manufacturer customers. If you want to know more about how to choose plastic mold steel, please feel free to contact us.
