Material Selection for Automotive Injection Molds

The selection of materials for automotive injection molds requires comprehensive consideration of factors such as plastic type, product requirements, and production scale. Commonly used mold steels include:

1. P20 steel: Pre-hardened mold steel, suitable for manufacturing injection molds with low to medium complexity and small to medium batch production, such as automotive interior parts.

2. 718H steel: An improved and upgraded version of P20 steel, suitable for manufacturing high-precision, long-life medium to large-sized injection molds, such as automotive functional parts.

3. NAK80 steel: Pre-hardened mirror-finish mold steel, with excellent polishing performance, suitable for manufacturing transparent parts and high-gloss surface products, such as high-gloss automotive grilles.

4. H13 steel: Hot-work mold steel, suitable for high-temperature engineering plastic products, such as automotive engine hoods.

5. S136 steel: High-chromium stainless steel mold steel, with excellent corrosion resistance and polishing properties, suitable for injection molds of corrosive plastics, such as medical device components.
