Description
Plastic mould steel P20 DIN 1.2311, 3Cr2Mo, SKT3, superior stockists in Delhi, Haryana, Manesar.
What is Plastic Mould steel.
Plastic mould steel is a type of tool steel specifically designed for manufacturing plastic injection molds, compression molds, and other tooling used in plastic processing.
It has properties that make it suitable for shaping and forming plastic materials under high pressure and temperature.
Characteristics of Plastic Mould Steel
- High Hardness & Wear Resistance – Ensures long mold life and maintains shape under repeated use.
- Good Toughness & Impact Strength – Prevents cracking or breaking under stress.
- High Polishability – Important for producing high-gloss plastic parts (e.g., optical lenses, transparent plastics).
- Good Machinability – Allows easy milling, drilling, and grinding to create complex mold shapes.
- Corrosion Resistance – Some grades have high chromium content to resist rusting, especially for molds used with corrosive plastics like PVC.
- Thermal Stability – Can withstand high molding temperatures without significant deformation.
Common Grades of Plastic Mould Steel
- P20 (1.2311 / 1.2312) – A widely used pre-hardened steel (28-34 HRC), good for general plastic molding.
- H13 (1.2344) – A hot work steel, used for high-temperature plastic molding.
- 420 Stainless Steel – Corrosion-resistant and used for high-gloss finishes.
- S136 / 2083 – Stainless steel grades with excellent corrosion and wear resistance.
Applications
- Injection molds
- Blow molds
- Compression molds
- Extrusion dies
- Plastic forming tools
Would you like help selecting the right steel for a specific mold application?
P-type or ‘plastic mold steel’ are categorized with the prefix ‘p’ and are designed to be suitable for plastic injection moulding zinc die casting and dies.
Our plastic mold steels are relatively corrosion-resistant and used to manner plastic moulds, which can contain chemically aggressive or abrasive fillers.
Principles.
P20 DIN 1.2311, 3Cr2Mo, SKT3 is in the category commonly classified as mold steels.
chromium and Nickel are the alloying factors for hardness and durability. This alloy is most customarily used in the carburized circumstance.
