VINACNC - Expert in Custom HSS, SUS, and Tungsten Steel Punch Pins & Carbide Bushings

In the mould and stamping industry, punch pins and drilling bushes are core components that determine the precision and lifespan of the mould. VINACNC is proud to offer a manufacturing service for customizable punch pins and guide bushings made from high-grade materials like HSS, SUS, Tungsten steel, and especially Tungsten Carbide. We are committed to providing high-quality, durable, and absolutely precise mould components.

Technical Specifications, Materials, and Applications

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

  • HSS (High-Speed Steel): Known for its good hardness and wear resistance, suitable for high-speed applications.

  • SUS (Stainless Steel): Excellent corrosion resistance, ideal for harsh environments.

  • Tungsten Steel and Tungsten Carbide: Extremely high hardness and wear resistance, suitable for applications demanding maximum durability.

• Technical Properties:

  • High-Precision CNC Machining: Components are machined using advanced CNC technology to achieve extremely tight tolerances, which helps to create parts with precise and uniform dimensions.

  • Flexible Customization: We can customize features such as punch pin shape (round, oval, stepped head, etc.), dimensions, and other complex details to meet specific production needs.

• Applications: Our components are indispensable parts of various moulds:

  • Stamping Die Molds: Used for cutting and punching holes in sheet metal.

  • Die Cutting Moulds: Specialized for precision hole punching.

Product Advantages

• Superior Durability: With high-quality materials, the components resist repetitive force and pressure, significantly extending the mould's lifespan.

• Absolute Precision: Dimensions are strictly controlled down to the micrometer 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.

• Competitive Pricing: Thanks to our optimized and efficient production process, we can offer products at a very competitive price.

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 components 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.
