VINACNC - Expert in High-Precision SKD11 and M2 Punch Pins

In the mold and stamping industry, the punch pin is a core component that determines the precision and efficiency of the production process. VINACNC is proud to supply SKD11 and M2 perforating punch pins manufactured to the high standard of DIN9861 D. We are committed to providing high-quality, durable, and absolutely precise mold components.

Technical Specifications, Materials, and Applications

• Materials: The products are crafted from high-quality tool steels:

  • SKD11 Steel (JIS): A common stamping die steel known for its hardness, wear resistance, and toughness after heat treatment.

  • M2 High-Speed Steel (HSS): This steel has high hardness and heat resistance, making it ideal for high-speed perforating applications.

• Technical Properties:

  • Standard: Products comply with the DIN9861 D standard, ensuring compatibility and high quality.

  • Precision: The products are machined with extremely tight diameter tolerances, ensuring a perfect fit with the die and helping to create parts with precise dimensions.

  • Surface Finish: The surface is specially treated to achieve a high smoothness (e.g., polished finish), which reduces friction and extends the lifespan of the punch pin.

• Applications: SKD11 and M2 punch pins are indispensable components in stamping dies for cutting and perforating sheet metal or plastic parts. They are also used in plastic injection molds for complex hole-punching needs.

Product Advantages

• Superior Durability: With high-quality SKD11 and M2 materials, the punch pins resist repetitive force and pressure during production, extending the mould's lifespan.

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

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

• High Wear Resistance: The meticulously machined and polished surface gives the punch pins high wear resistance, allowing them to withstand millions of production cycles.

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 pin is cleaned and coated with a specialized anti-rust oil to protect its precision surfaces.

• Secure Packaging: The product is carefully packed in a rigid plastic box or a cardboard crate with foam to prevent damage during transport.

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

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