VINACNC - Expert in High-Precision and Sharp Punch Pins for Stamping Dies

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 supply precision sharp special mold punch pins with high hardness and tight tolerances, designed to ensure 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 SKH51. These materials are known for their high hardness, wear resistance, and good toughness after heat treatment.

• Technical Properties:

  • Sharpness and Precision: The punch pins are meticulously machined using advanced CNC technology to achieve a sharp cutting edge and extremely tight tolerances. This ensures clean and precise hole punching.

  • 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.

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

• Applications: Punch pins are indispensable components in stamping dies for cutting and punching holes in sheet metal or plastic parts.

Product Advantages

• Superior Durability: With high-quality steel materials, the punch pin resists 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 sharp cutting edge and smooth operation help to reduce the stamping cycle time and enhance overall production efficiency.

• Customization Service: We provide a custom manufacturing service from design and mold development to mass production, ensuring the product perfectly matches the client's blueprints and intended use.

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.
