Characteristics of S136 steel injection mold

1. Corrosion resistance

S136 steel has extremely high corrosion resistance and is particularly suitable for manufacturing molds that require high mold surface finish and require frequent use of water-based cooling. This makes it ideal for the production of optical products or products with high surface requirements.

2. Hardness

With proper heat treatment, S136 steel can reach very high hardness, usually between 50-54 HRC. This high hardness allows the mold to have a longer service life and withstand the injection molding process under high pressure.

3. Polishing performance

S136 steel has excellent polishing properties and can achieve a mirror effect, so it is often used in molds that require a highly bright surface.

4. Processability

S136 steel has good machinability and, despite its higher hardness, can still be precision machined by conventional machining methods.

5. Wear resistance

Due to its high hardness and corrosion resistance, S136 steel exhibits good wear resistance during injection molding.

S136 steel processing precautions

S136 steel usually requires quenching and tempering to achieve optimal mechanical properties.

Standard heat treatment process can make its hardness reach 50-54 HRC.

What products is S136 steel suitable for in injection mold manufacturing?

1. Optical products: plastic lenses, transparent plastic parts, etc.

2. Medical devices: Plastic injection molds that require a high degree of cleanliness and corrosion resistance.

3. Food industry: Due to its stainless and corrosion-resistant properties, S136 steel is often used in the food industry to make plastic containers or packaging and other types of molds.

4. Electronic products: Plastic shells and component injection molds that require high surface finish and precision.

Summarize

Injection molds manufactured using S136 steel have excellent corrosion resistance, polishing performance and high hardness, and can achieve injection molding production of plastic parts with high requirements on surface quality and durability.
