P20 mould steel is one of the most commonly used pre-hardened mould steels in the plastic injection mould industry.
It belongs to chromium-molybdenum alloy mould steel with stable mechanical performance, excellent machining ability and reasonable overall manufacturing cost.
In the production practice of HUAJI MOULD, P20 steel is widely used in medium and large plastic mould projects, especially for plastic chair moulds, paint bucket moulds and large structural injection moulds.
Good cutting performance helps shorten mould manufacturing cycle
High toughness reduces the risk of cracking in large moulds
Stable polishing performance suitable for general appearance plastic products
Surface nitriding treatment can improve mould wear resistance
Cost-effective solution for mass production mould projects
Lower hardness compared with higher grade steels such as 718 or H13
Not suitable for ultra-high gloss mirror surface plastic products
Moderate corrosion resistance when processing corrosive plastic materials
Limited performance in high-temperature engineering plastic injection moulding
P20 mould steel is suitable for common plastic materials such as PP, PE and ABS.
With its balanced performance and economical cost, it has become an ideal material choice for large furniture injection moulds.
HUAJI MOULD can provide professional mould steel selection suggestions based on customer material requirements, production volume, appearance standards and investment budget, helping customers achieve the best balance between mould service life and overall investment cost.
