VINACNC - Expert in High-Precision Punch Die Bushings and EDM Mold Components

As a leading manufacturer in Vietnam, VINACNC is proud to supply punch die bushings with exceptional precision and durability. We specialize in manufacturing high-quality EDM mold components, ensuring maximum performance and longevity for stamping and injection molds, and meeting the stringent standards of the industry.

Technical Specifications, Materials, and Applications

• Material: The products are crafted from high-quality tool steels such as SKD-11, M2, or other premium materials as per customer requirements. These materials are known for their high hardness, wear resistance, and good toughness after heat treatment.

• Technical Properties:

  • High Precision: The guide bushings are CNC machined with extremely tight diameter tolerances, ensuring a perfect fit with the guide pin and allowing for a smooth mold opening and closing process.

  • Hardness: After heat treatment, the material achieves a stable hardness (typically HRC 58-62°), enabling the guide bushing 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 component.

• Applications: Punch die bushings are indispensable components in 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, our guide bushings resist repetitive force and friction, 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 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.

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 guide bushings 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.
