What is P20+Ni Plastic Mold Steel?

P20+Ni plastic mold steel is a high-quality, pre-hardened tool steel alloy. It offers exceptional hardness and durability, making it ideal for injection molding applications. The addition of nickel increases its toughness and provides better thermal stability, which is crucial for high-pressure molding processes.

Key Properties of P20+Ni Plastic Mold Steel

The properties of P20+Ni plastic mold steel that make it suitable for injection molds include:

  • High Hardness: Typically around 42-48 HRC, ensuring resistance to wear.
  • Excellent Toughness: Reduces the risk of cracking during the production process.
  • Good Corrosion Resistance: Especially important in harsh working environments.
  • High Thermal Conductivity: Ensures effective heat dissipation during molding cycles.

Advantages of Using P20+Ni Plastic Mold Steel

Choosing P20+Ni offers several advantages for mold makers:

  • Improved Mold Life: Due to its wear and impact resistance, molds crafted from this material last longer.
  • Better Surface Finish: Allows for greater detail in the molded parts, which can improve end-product quality.
  • Cost-Effectiveness: Although initial costs may be higher, the longevity and reduced maintenance can lead to savings in the long run.
