Plastic Mould Steel Grades Available at Hamiran Steel
DIN 1.2311 / AISI P20 Plastic Mould Steel
DIN 1.2311 is the European equivalent of AISI P20 plastic mould steel and is one of the most widely used mould steels globally.
Key Features:
• Pre-hardened condition (typically 28–34 HRC)
• Good machinability
• Excellent polishability
• Balanced strength and toughness
• Suitable for medium to large moulds
Applications:
• Automotive plastic components
• Consumer goods moulds
• Industrial injection moulds
• Structural mould bases
This grade provides a cost-effective and reliable solution for medium to high production tooling.
1.2312 Plastic Mould Steel
1.2312 is a modified version of 1.2311 with improved machinability due to controlled sulfur content.
Advantages:
• Enhanced machinability
• Uniform hardness distribution
• Suitable for large mould bases
• Reduced production time
Ideal for mould bases and structural mould components requiring efficient machining.
1.2083 Tool Steel for Plastic Moulds
1.2083 is a high-chromium tool steel offering superior corrosion and wear resistance.
Key Characteristics:
• High hardness
• Excellent corrosion resistance
• Superior wear resistance
• Mirror polish capability
Applications:
• Medical plastic moulds
• Food-grade moulds
• Transparent plastic products
• High-volume precision moulds
This grade is ideal when surface finish quality and corrosion resistance are critical.
How to Choose the Right Plastic Mould Steel
Selecting the correct mould steel depends on several factors:
Production Volume
High production volumes require better wear resistance such as 1.2083.
Surface Finish Requirements
Mirror finish applications benefit from 1.2083, while general moulds commonly use 1.2311 / P20.
Machining Efficiency
For easier machining and reduced manufacturing time, 1.2312 is recommended.
Cost–Performance Balance
DIN 1.2311 / AISI P20 provides an optimal balance between cost and performance.
