Plastic Mould Steel

Plastic Mould Steel

Plastic Mould Steel refers to a group of specially engineered steels designed for the manufacturing of plastic injection moulds, blow moulds, extrusion dies, and compression moulds. These steels are developed to provide excellent machinability, polishability, toughness, and dimensional stability, ensuring consistent performance and long service life. Their ability to produce high-quality surface finishes makes them essential in industries such as automotive, packaging, consumer goods, and electronics.

Their ability to produce high-quality surface finishes makes them essential in industries such as automotive, packaging, consumer goods, and electronics.

These steels are specifically formulated to withstand demanding operating conditions, including high injection pressures, repeated thermal cycles, surface wear, and, in some grades, corrosion. Depending on the application, plastic mould steels are available in both pre-hardened and through-hardened conditions, allowing manufacturers to choose materials based on production volume, complexity, and performance requirements.

Advanced ESR (Electro-Slag Remelted) grades such as 1.2083 ESR, 1.2738 ESR, and VR 16 HH ESR provide ultra-high purity, excellent mirror polishability, and superior hardness uniformity. These steels are widely used in high-end applications like optical components, transparent moulds, and precision tooling where surface finish and dimensional accuracy are critical.
