VINACNC - Expert in High-Precision and Customizable SKD-11 Punch Pins

In the mold industry, the punch pin is a core component that determines the precision and efficiency of the stamping process. VINACNC is proud to supply premium SKD-11 punch pins with high hardness and tight tolerances, ensuring superior performance and durability even under harsh production conditions. Our products are available at a competitive factory-direct price and can be tailor-made in a wide range of sizes to meet your specific needs.

Technical Specifications, Materials, and Applications

• Material: The product is crafted from SKD-11 tool steel (JIS), a high-quality steel widely used for its hardness, wear resistance, and good toughness after heat treatment.

• Technical Properties:

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

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

  • Surface Finish: The surface is specially treated to achieve high smoothness, such as with a carbide polishing finish, which reduces friction and extends the lifespan of the punch pin.

• Applications: SKD-11 punch pins are indispensable components in stamping dies for cutting and punching holes in sheet metal or plastic parts, used in industrial machinery and other tooling.

Product Advantages

• Wide Range of Sizes and Flexible Customization: We offer punch pins in a variety of sizes and can customize them according to specific customer requirements, ensuring the product is a perfect fit for any mold application.

• Superior Durability: With high-quality SKD-11 material, the punch pin resists repetitive force and pressure during production, extending the mould's lifespan.

• Absolute Precision: Dimensions are strictly controlled down to the micrometer level, ensuring the punch pin operates in perfect conjunction with the die, minimizing the risk of product defects.

• Competitive Factory-Direct Pricing: Thanks to our optimized and efficient production process, we can offer products directly from our factory, helping clients reduce intermediary costs and increase profits.

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. Functionality 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.
