H13 Steel Precision Machined Heat Resistant Ejector Pins and Core Pins for Die Casting Molds

H13 Steel Ejector Pins and Core Pins are precision mold components widely used in die casting molds and plastic injection molds. These parts play a critical role in the molding process by forming internal features and assisting with the ejection of finished parts from the mold cavity.

Manufactured from high-quality H13 tool steel, these pins provide excellent heat resistance, wear resistance, and dimensional stability under high-temperature molding environments. Their durability makes them particularly suitable for demanding industrial applications such as aluminum die casting and high-cycle plastic injection molding.

With precise machining and heat treatment processes, these ejector pins and core pins deliver reliable performance, long service life, and consistent molding accuracy.

Ejector pins and core pins are essential components in mold tooling systems. Each serves a specific function within the molding process.

Ejector Pins are responsible for pushing molded parts out of the mold cavity once the molding cycle is complete. They must maintain precise alignment and smooth movement to avoid damaging the molded product.

Core Pins are used to create internal holes, cavities, or complex geometries within molded parts. These pins are positioned inside the mold cavity and directly shape the final product.

• Manufactured from premium H13 hot-work tool steel
• High resistance to heat, wear, and mechanical stress
• Precision ground surfaces for smooth mold operation
• Tight dimensional tolerances for accurate mold assembly
• Customizable sizes and shapes based on mold design requirements

These pins are produced with high machining accuracy to ensure compatibility with various mold structures.

H13 ejector pins and core pins are widely used across multiple mold manufacturing industries.
