The detail information of product

VINACNC - Expert in High-Precision Tungsten Carbide Punch Pins and Accessories

In the mould and stamping industry, punch pins and their accompanying accessories are core components that determine the precision and efficiency of the production process. VINACNC is proud to offer manufacturing services for tungsten carbide punch pins and die accessories, ensuring superior performance and durability even under the most demanding production conditions.

Technical Specifications, Materials, and Applications

Materials: The products are crafted from tungsten carbide steel (hard alloy), which is known for its extremely high hardness and wear resistance. This is an ideal material for applications that are subject to heavy loads and high friction.
Technical Properties:
- Piercing Pin: Specially designed for piercing precise holes in sheet metal. The punch pin can be CNC machined to achieve extremely tight tolerances, ensuring sharpness and long lifespan.
- Punching Needle Accessory: These accessories are designed to support the punching process, especially in hollow pin punching machines, ensuring high efficiency and accuracy.
- Precision: Products are CNC machined with extremely tight diameter tolerances, ensuring a perfect fit with the mold 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 tungsten carbide 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 cycle time and enhances overall production efficiency.
High Wear Resistance: The super-precision machined surface gives the components high wear resistance, allowing them to withstand millions of production cycles.

Post-Machining Product Inspection Process

Hardness Test: We use a professional hardness tester to verify the hardness of the material.
Dimensional and Tolerance Check: We use a Coordinate Measuring Machine (CMM) to verify all critical dimensions and tolerances against the technical drawings.
Surface Inspection: We use a surface roughness tester and visual inspection to ensure there are no cracks, scratches, or other defects.
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.
