VINACNC - Expert in High-Precision HSS Punch Pins (DIN9861 Standard)

In the mold 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 HSS punch pins, which meet the stringent international standard of DIN9861. Our products, which feature a polished finish, are designed to deliver superior performance and durability for household & vehicle molds.

Technical Specifications, Materials, and Applications

• Materials: The products are crafted from HSS (High-Speed Steel), a high-quality tool steel renowned for its hardness, wear resistance, and toughness after heat treatment.

• Standards:

  • DIN9861: The punch pins and dies are manufactured according to the international standard DIN9861, ensuring high compatibility and quality.

• Technical Properties:

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

  • Precision: Products are CNC machined to extremely tight tolerances, ensuring a perfect fit with the die and creating parts with precise dimensions.

  • Polished Finish: The surface is specially treated to achieve a high-quality polished finish, which minimizes friction and extends the lifespan of the pins.

• Applications: HSS punch pins are essential components in stamping moulds for cutting and punching holes in sheet metal or plastic parts. They are widely used in the manufacturing of household & vehicle moulds, automotive parts, and precision machinery.

Product Advantages

• Superior Durability: Made from high-quality HSS steel, our punch pins resist repetitive force and pressure, significantly extending the mould's lifespan.

• Absolute Precision: Dimensions are strictly controlled down to the micrometre level, ensuring the components operate in perfect conjunction and minimizing the risk of product defects.

• Optimized Performance: The polished surface and high precision help to reduce the stamping cycle time and enhance overall production efficiency.

• International Standard Compliance: Manufacturing according to the DIN9861 standard ensures high compatibility and quality, making it easier for clients to integrate our components into their existing systems.

Post-Machining Product Inspection Process

1. Hardness Test: We use a professional hardness tester to verify the hardness of the heat-treated material, ensuring it meets technical specifications.

2. Dimensional and Tolerance Check: We use a Coordinate Measuring Machine (CMM) or other high-precision measuring instruments 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 punch 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.
