In the world of plastic injection molding, achieving high precision is essential. Many manufacturers grapple with the challenge of selecting the right mold steel hardness, which directly impacts the durability and quality of the final product.
The company is the world’s best Plastic mold steel hardness chart supplier. We are your one-stop shop for all needs. Our staff are highly-specialized and will help you find the product you need.
The plastic mold steel hardness chart is a valuable resource that provides essential information on the hardness levels of various mold steels. It serves as a guide for manufacturers in selecting the right material for their specific applications, ensuring both efficiency and quality in production.
The hardness of mold steel significantly affects wear resistance, machinability, and overall mold life. According to a study by the American Society for Testing and Materials (ASTM), the right hardness can reduce maintenance costs by up to 20% and extend the mold's lifespan.
Mold Steel Type | Hardness (HRC) | Applications |
---|---|---|
P20 | 28-32 | General purpose molds |
S136 | 48-52 | High-precision molds |
H13 | 45-50 | Hot runner molds |
A leading automotive parts manufacturer was facing frequent mold failures due to incorrect hardness selection. By utilizing the plastic mold steel hardness chart, the company switched to S136 which enhanced mold longevity and reduced production delays by 30%. The initial investment in higher-quality steel resulted in substantial long-term savings.
Consider the type of part, the expected production volume, and the required precision. Always refer to the hardness chart for guidance.
