VINACNC - Expert in High-Quality, Customizable Core Pins and Ejector Pins

In the mold industry, core pins and ejector pins are fundamental components that determine the precision and efficiency of the production process. VINACNC is proud to offer a manufacturing service for high-quality customized core pins and ejector pins at a competitive wholesale price, meeting the most stringent standards for household appliance molds.

Technical Specifications, Materials, and Applications

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

• Technical Properties:

  • Core Pins: Specially designed to create holes, grooves, or complex shapes in plastic parts. Our core pins are CNC machined to achieve extremely tight tolerances, ensuring absolute precision.

  • Ejector Pins: Used to smoothly eject parts from the mold, preventing deformation and damage.

  • Hardness: After heat treatment, the material achieves a stable hardness (typically HRC 58-62°), allowing the components 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 mold and minimizing defects.

• Applications: Our components are indispensable parts of injection molds for household appliances, automotive parts, and precision machinery.

Product Advantages

• Superior Durability: Made from high-quality steel materials, our components resist repetitive force and pressure, extending the mold's lifespan.

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

• Optimized Performance: The smooth operation of our pins and punches helps reduce the cycle time and enhances overall production efficiency.

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

• Competitive Wholesale Price: Thanks to our optimized production process, we can offer products at a very competitive wholesale price.

Post-Machining Product Inspection Process

1. Hardness Test: We use a professional hardness tester to verify the hardness of the heat-treated material.

2. Dimensional and Tolerance Check: We use a Coordinate Measuring Machine (CMM) to check the diameter, length, and concentricity.

3. Surface Inspection: We use a surface roughness tester and visual inspection to ensure there are no cracks, scratches, or other defects.

4. 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.
