High-Quality Punch Pins: The Optimal Solution for Precision Stamping Dies

The detail information of product

VINACNC - Expert in High-Precision MISUMI Standard Punch Pins for Die Stamping

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 offer a manufacturing service for high-quality MISUMI standard punch pins with high hardness and tight tolerances, ensuring superior performance and durability even under harsh production conditions.

Technical Specifications, Materials, and Applications

Materials: Our 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 good toughness after heat treatment.
Standards:
- MISUMI: Our punch pins and dies are manufactured to MISUMI international standards, ensuring high compatibility and quality, which makes them easy to replace and integrate into existing moulds.
Technical Properties:
- 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.
- Precision: The products are CNC machined with extremely tight diameter tolerances, ensuring a perfect fit with the die and helping to create parts with precise dimensions.
- 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 and dies are indispensable components in stamping dies for cutting and punching holes in sheet metal or plastic parts. They are widely used in the manufacturing of automotive parts, electronic device housings, and precision machinery.

Product Advantages

Superior Durability: With high-quality steel materials, the punch pins 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 and minimizing the risk of product defects.
Optimized Performance: The smooth operation helps reduce the stamping cycle time and enhances overall production efficiency.
International Standard Compliance: Manufacturing according to MISUMI standards ensures high compatibility and quality, making it easier for clients to integrate our components into their existing systems.

Post-Machining Product Inspection Process

Hardness Test: We use a professional hardness tester to verify the hardness of the heat-treated material, ensuring it meets technical specifications.
Dimensional and Tolerance Check: We use a Coordinate Measuring Machine (CMM) or other high-precision measuring instruments to check the diameter, length, and concentricity.
Surface Inspection: We use a surface roughness tester and visual inspection to ensure there are no cracks, scratches, or other defects.
Functional Test: 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 products in a dry, cool environment, away from high humidity and corrosive chemicals.
