Introduction to three types of injection mould steels commonly used by our company

2024-02-22

1. H13

H13 is a hot work die steel that complies with the standard GB/T1299-2000. ; Brand 4Cr5MoSiV1; Alloy tool steel, referred to as alloy steel, is a type of steel formed by adding alloying elements to carbon industrial steel. Among them, synthetic steel includes steel for measuring tools and cutting tools, steel for impact-resistant tools, cold work mold steel, hot work mold steel, non-magnetic mold steel, and plastic mold steel. H13 die steel is used to manufacture forging dies with large impact loads, hot extrusion dies, precision forging dies; aluminum, copper and their alloy die-casting dies.

Some of our Auto Structural components molds use H13 steel, as shown below:

2. S136

S136 has a high-gloss surface and low maintenance costs. It also has the characteristics of a low deformation rate and high surface precision. It can still maintain the original high precision after long-term production and can be produced in cameras, sunglasses, chemical instruments, plastic products, etc. S136 steel is also used for internal mold parts with a high polishing degree and high requirements, high corrosion resistance plastic molds, production, medical, food industry and other products.

Many of the Medical Repair Parts Mould we design use S136 steel, as shown below

3. 718
The use of 718 mold steel is the same as that of P20 type mold steel, but due to its better hardenability and superior performance, it can produce large-sized, high-grade plastic mold forming parts. With the development of plastic molds, more, better and newer improved mold steel grades will appear. 718 can be used in thermoplastic injection molds, extrusion molds, thermoplastic blow molds, main parts of heavy-duty molds, and cold structural parts. It is often used in the manufacture of TV casings, washing machines, refrigerator inner casings, buckets, etc.

Some of our Aero Interior parts molds use 718 steel, as shown below
