Plastic Moulding Steel

Plastic molding steel, also known as tool steel, is a specialized type of steel designed specifically for the demanding requirements of plastic injection molding processes. These steels must exhibit exceptional properties such as high hardness, wear resistance, toughness, and thermal conductivity to withstand the extreme conditions encountered during plastic molding. One such steel widely used in this industry is P20 tool steel, renowned for its reliability and versatility.

Key features:

1. Chemical Composition: P20 tool steel typically contains a balanced composition of carbon, chromium, manganese, and molybdenum. The exact composition may vary slightly based on the specific grade or manufacturer, but the overall aim is to achieve a combination of hardness and toughness suitable for plastic molding applications.

2. Hardness and Wear Resistance: P20 tool steel is renowned for its excellent hardness, typically in the range of 28-32 HRC (Rockwell Hardness C scale). This high hardness level ensures the steel can withstand the abrasive wear and high stresses encountered during plastic injection molding, prolonging tool life and reducing maintenance downtime.

3. Toughness and Impact Resistance: Alongside hardness, P20 steel exhibits good toughness and impact resistance, crucial properties for withstanding the mechanical stresses and impacts associated with plastic molding processes
