H13 steel is a tool steel material commonly used to make injection molds. It not only has good thermal stability and wear resistance, but also can withstand working conditions at high temperatures. It is very suitable for producing plastic molds with complex shapes and precise dimensions.

H13 steel can be specially treated to improve its mechanical properties, including hardness, toughness and fatigue crack resistance. When manufacturing injection molds, H13 alloy steel material is widely used.

Advantages of H13 steel mold

1. Excellent thermal strength

H13 steel can maintain high hardness and strength under high temperature conditions, which is particularly important for plastic materials that need to be molded at high temperatures. It can effectively maintain the structural integrity and dimensional stability of the mold.

2. Good wear resistance

Due to the presence of hard phases such as carbides and nitrides, H13 steel exhibits excellent wear resistance, which helps the mold resist wear under long-term high-intensity working conditions and extend the service life of the mold.

3. Good heat resistance

H13 steel can maintain high hardness and strength at high temperatures, reducing performance degradation caused by temperature changes, and is suitable for the manufacture of high-temperature hot work molds.

4. Good processing performance

H13 steel is easy to process into mold parts of various shapes and sizes, helping to improve the processing efficiency and accuracy of molds.

5. Anti-fatigue performance

H13 steel has good toughness and can withstand cyclic loads at high temperatures and resist the occurrence of thermal fatigue cracks. This is very important for injection molds because they often work under repeated cyclic pressures.

6. Heat treatment performance

H13 steel can obtain the required hardness and toughness through conventional heat treatment processes, such as quenching and tempering, to adapt to different working conditions.

7. Antioxidant properties

Molds working at high temperatures are susceptible to oxidation and corrosion. The alloy elements in H13 steel help improve the material's anti-oxidation properties and protect the mold surface from damage.

H13 steel injection mold supports processing of plastic materials

Polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), polystyrene (PS), polycarbonate (PC), ABS resin, nylon (PA), polyimide (PI), poly Ether ether ketone (PEEK)

H13 steel injection mold manufacturing cost

The price of high-quality H13 steel ranges from several thousand yuan to tens of thousands of yuan per ton. The prices of H13 steel molds of different sizes and shapes are also different. The larger the size, the higher the price is usually.

Design and manufacturing costs usually account for 40-50% of the entire mold manufacturing cost, including mold structural design, product design and mold drawing production, precision machining, EDM, wire cutting, assembly and debugging and other processes.

The size and complexity of the mold directly affect the manufacturing cost. Larger-sized molds require more raw materials and processing time. Complex mold structures and detailed requirements will increase the difficulty and process requirements in the manufacturing process.

Summarize

In the field of injection molds, H13 steel can withstand high temperature and high pressure working environments, ensuring the stability and service life of the mold, and is very suitable for the manufacture of injection molds.
