Characteristics of 718 plastic mould steels:
The material demonstrates exceptional mechanical properties and uniform hardness following treatment. It allows for excellent polishing and reduced surface roughness. Typically, heat treatment is applied to harden the steel before usage; however, it can be utilized directly after the mould has been machined, with surface hardening processed as necessary.
Applications of 718 plastic mould steel:
This type of steel is ideal for manufacturing plastic molds and exhibits outstanding corrosion resistance, particularly in wet environments. It is extensively used in creating high-quality transparent plastic molds.
