Classification of steel raw materials

There are many types of steel raw materials for #injectionmolds. Different steels have different characteristics and are suitable for different application scenarios. Common injection mold steels include:

Electronic product injection mold

P20: This is a pre-hardened plastic mold steel with good processing and polishing properties, moderate hardness, and is suitable for general #plasticproductproduction, such as toys, toys, daily necessities, etc. Its price is relatively affordable and is one of the commonly used materials for small and medium-sized #moldmanufacturers.

Electronic housing injection mold

718: It is a high-quality pre-hardened plastic mold steel with higher hardness and strength than P20, and better wear resistance. It is often used to manufacture injection molds with high precision requirements and good surface quality requirements, such as automotive interior parts, electronic product housings, etc.

Electronic housing accessories processing

738: Further optimized on the basis of 718, it has better polishing performance and dimensional stability, and is suitable for manufacturing large and precise injection molds, such as home appliance housings, large industrial parts, etc.

Medical accessories mold

S136: This is a corrosion-resistant mold steel with excellent corrosion resistance and mirror polishing performance. It is particularly suitable for the production of plastic products that come into contact with corrosive plastics or chemicals, such as medical devices, food packaging, etc.

NAK80: Aging-hardening mold steel with extremely high hardness and mirror polishing performance, and small heat treatment deformation. It is often used to manufacture injection molds with high precision and high finish requirements, such as optical lens molds, mobile phone housing molds, etc.

Choosing the right steel raw material is crucial to the performance and life of the injection mold. When deciding on the type of steel, it is necessary to comprehensively consider factors such as the requirements of plastic products, production batches, and cost budgets.
