VINACNC - Expert in High-Precision Customized Tapered Punch Pins for Moulds

In the mould and stamping industry, punch pins are a core component that determines the precision and efficiency of the production process. VINACNC is proud to offer a manufacturing service for high-quality customized tapered punch pins with high hardness and tight tolerances, ensuring superior performance and durability even under harsh production conditions.

Technical Specifications, Materials, and Applications

• Materials: The products are crafted from high-quality tool steels such as SKD-11, M2, and HSS. These materials are known for their high hardness, wear resistance, and toughness after heat treatment.

• Technical Properties:

  • Tapered Head: The tapered head design minimizes friction during punching and allows for easy positioning, making it suitable for stamping dies and punching machines.

  • 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 die and helping to create parts with precise dimensions.

• Applications: Customized tapered punch pins are indispensable components in stamping dies and injection molds for cutting and punching holes in sheet metal or plastic parts. They are widely used in the manufacturing of hardware machinery, automotive parts, and precision tooling.

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 and shapes are strictly controlled down to the micrometre level, ensuring the final product is of the highest quality.

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

• Flexible Customization: We provide a custom manufacturing service, from design to machining, ensuring the product perfectly matches the client's blueprints and intended use.

Quality 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 verify all critical dimensions and tolerances against the technical drawings.

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

4. Functional Test: Components are test-fitted with related parts to ensure a perfect fit and smooth operation.

Packaging and Storage Process

• Cleaning and Rust Prevention: The pins are cleaned and coated with a specialized anti-rust oil to protect their precision surfaces.

• 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.
