VINACNC - Expert in High-Precision Oblong Punch and Dies for Stamping

In the mould and stamping industry, punch pins (poinçon) and dies (matrice) are core components that determine the precision and efficiency of the production process. VINACNC is proud to offer a manufacturing service for high-quality oblong punch and dies that are popular in France. We provide products with high hardness and tight tolerances, ensuring 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 HSS. These materials are known for their high hardness, wear resistance, and toughness after heat treatment.

• Technical Properties:

  • Oblong Shape: The special oblong (oval) design of the punch and die ensures precise positioning and focused punching force, making it suitable for press dies and stamping machines.

  • Hardness: After heat treatment, the material achieves a stable hardness (typically HRC 58-62°), allowing the 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 mold and creating 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 micrometer level, ensuring the components operate in perfect conjunction, minimizing the risk of product defects.

• Optimized Performance: The excellent design and surface finish help to reduce the stamping cycle time and enhance 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 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.
