What types of plastic mold steel are there?

Plastic molds are important tools for the production of plastic products. Their materials determine the service life and molding effect of the mold. Steel is a common plastic mold material. Because of its high hardness, good wear resistance, good processing performance, and corrosion resistance, it is widely used in plastic mold manufacturing.

 

What types of plastic mold steel are there?

 

The following are several commonly used plastic mold steel models and specifications:

1. S136H stainless steel
S136H is a high-quality stainless steel with good corrosion resistance, thermal stability and precision retention. It is suitable for injection molding products with high requirements, such as mobile phone housings, electronic parts, etc.

Standard specifications: sheet thickness ranges from 15mm to 500mm; round bar diameter ranges from 8mm to 500mm.

2. P20 low alloy steel
P20 low alloy steel is a cost-effective steel with good wear resistance and extrusion performance. It is widely used in the production of injection molds.

Standard specifications: Plate thickness ranges from 10mm to 300mm; round bar diameter ranges from 8mm to 400mm.

3. 2316 stainless steel
2316 stainless steel is a high-strength stainless steel with good wear resistance and extrusion performance. This steel is suitable for the production of precision plastic parts, such as medical devices, automotive parts, etc.

Standard specifications: Plate thickness ranges from 10mm to 300mm; round bar diameter ranges from 8mm to 400mm.

4. NAK80 steel
NAK80 steel is a high-quality steel with excellent wear resistance, corrosion resistance and extrusion performance. It is widely used in the manufacture of injection molds.

Standard specifications: Plate thickness ranges from 10mm to 300mm; round bar diameter ranges from 8mm to 400mm.

5. H13 tool steel
H13 tool steel is a steel that is resistant to thermal shock at high temperatures and is suitable for the production of plastic products that need to withstand high temperatures, such as electrical housings, automotive parts, etc.

Standard specifications: Plate thickness ranges from 10mm to 300mm; round bar diameter ranges from 8mm to 400mm.

In short, it is very important to select the corresponding plastic mold steel according to the requirements of the injection molding product. The above commonly used steel models and specifications can provide customers with suitable options.
