VINACNC - Expert in High-Precision S136, HSS, and Tungsten Steel Punch Pins

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 non-standard oval punching needles and punch pins, crafted from high-grade materials like S136 steel, HSS (High-Speed Steel), and Tungsten steel. We are committed to providing high-quality, durable, and absolutely precise mould components.

Technical Specifications, Materials, and Applications

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

  • S136 Steel: A high-grade stainless steel known for excellent corrosion resistance and mirror-like polishing capability.

  • HSS (High-Speed Steel): Known for high hardness and good wear resistance.

  • Tungsten Steel: Features extreme hardness and wear resistance, suitable for applications demanding maximum durability.

• Technical Properties:

  • Special Shape: The punch pins have a special oval tip design, which ensures precise positioning and a focused cutting force, making them suitable for stamping molds.

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

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

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

Product Advantages

• Superior Durability: With high-quality steel materials, the components 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, minimizing the risk of product defects.

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

• Corrosion Resistance: S136 steel offers excellent corrosion resistance, ensuring the components perform reliably in harsh environments.

Post-Machining Product Inspection Process

1. Hardness Test: We use a professional hardness tester to verify the hardness of the heat-treated material.

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.
