VINACNC - Expert in High-Precision Countersunk Head Punch Pins (DIN 9861 D Standard)

In the mould and stamping industry, the punch pin is a core component that determines the precision and efficiency of the production process. VINACNC is proud to offer a manufacturing service for high-quality countersunk head punch pins, which meet the stringent international standard of DIN 9861 D. This is the optimal solution, ensuring superior performance and durability for precision punching and piercing applications.

Technical Specifications, Materials, and Applications

• Material: 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 good toughness after heat treatment.

• Standards:

  • DIN 9861 D: Our punch pins are manufactured according to the international standard DIN 9861 D, ensuring high compatibility and quality for seamless integration into existing mould systems.

• Technical Properties:

  • Countersunk Head: The countersunk head design of the punch pin ensures precise positioning and excellent compressive strength, making it suitable for press dies and punching machines.

  • High Precision: Products are CNC machined with extremely tight diameter tolerances, ensuring a perfect fit with the mould and helping to create parts with precise dimensions.

  • Surface Finish: The surface is specially treated to achieve high smoothness, which reduces friction and extends the lifespan of the punch pin.

• Applications: Countersunk head punch pins are indispensable components in stamping dies for cutting and punching holes in sheet metal or plastic parts. They are widely used in industries producing automotive components, electronic device housings, and precision machinery.

Product Advantages

• Superior Durability: With high-quality steel materials, the punch pins resist repetitive force and pressure during production, 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 excellent design and surface finish help to reduce the stamping cycle time and enhance overall production efficiency.

• International Standard Compliance: Manufacturing according to DIN 9861 D standard ensures compatibility and high quality, making it easier for clients to integrate our components into their 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) to verify all critical dimensions and tolerances against the technical drawings.

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.
