VINACNC - Expert in High-Precision Customizable Flat and Stepped Ejector Pins

In the mold industry, the ejector pin is a core component that determines the precision and efficiency of the part ejection process. VINACNC is proud to supply custom flat straight ejector pins and stepped ejector pins with high hardness and tight tolerances, ensuring superior performance and durability even under harsh production conditions.

Technical Specifications, Materials, and Applications

• Materials: Our products are crafted from high-quality tool steels such as SKD61, SKH51, and M2, or other materials as per customer requirements. These materials are known for their high hardness, excellent wear resistance, and good toughness after heat treatment.

• Technical Properties:

  • Flat Straight Ejector Pins: A simple, common design suitable for many applications, with a flat head for efficient ejection.

  • Stepped Ejector Pins: The stepped design ensures precise positioning and a focused ejection force.

  • Hardness: After heat treatment, the material achieves a stable hardness (typically HRC 58-62°), allowing the pins to withstand high pressure and friction during continuous operation.

  • Precision: Products are CNC machined with extremely tight diameter tolerances, ensuring a perfect fit with the mould and minimizing defects.

• Applications: Ejector pins are indispensable components in plastic injection molds and stamping dies. Their primary function is to smoothly and precisely eject the cooled product from the mold cavity, preventing product damage and mold sticking.

Product and Service Advantages

• Superior Durability: With high-quality steel materials, the components resist repetitive force and pressure, significantly extending the mould's lifespan.

• Absolute Precision: Dimensions are strictly controlled down to the micrometer level, ensuring components operate in perfect conjunction.

• Optimized Performance: The smooth operation helps to reduce the cycle time and enhances overall production efficiency.

• Flexible Customization: We provide a custom manufacturing service, from design and mould development to mass production, ensuring the product perfectly matches the client's blueprints.

Post-Machining Product Inspection Process

1. Dimensional and Tolerance Check: We use a Coordinate Measuring Machine (CMM) to check all critical dimensions and tolerances against the technical drawings.

2. Surface Inspection: We perform visual inspections and use specialized measuring devices to ensure the surface meets requirements, with no cracks or defects.

3. Functional Test: The components are test-fitted with related parts to ensure a perfect fit and smooth operation.

Packaging and Storage Process

• Cleaning and Rust Prevention: The components are cleaned and coated with a specialized anti-rust oil.

• Secure Packaging: Products are carefully packed in rigid plastic boxes or cardboard crates with foam to prevent damage during transport.

• Information Labeling: The packaging is clearly labeled with product information, including the product code, dimensions, and handling instructions.

• Storage Instructions: We recommend storing the products in a dry, cool environment, away from high humidity and corrosive chemicals.
