VINACNC - Expert in High-Precision Punch Pins and Ejector Sleeves for Metal Stamping

In the mold and stamping industry, punch pins and ejector sleeves are core components that determine the precision and efficiency of the production process. VINACNC is proud to supply high-quality punch pins and ejector sleeves for metal stamping, with a special focus on household appliance parts. We are committed to delivering high-quality, durable, and absolutely precise mould components.

Technical Specifications, Materials, and Applications

Materials: The components 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.
Technical Properties:
- Piercing Punch Pins: Specialized for punching precise holes in sheet metal. Punch pins can be CNC machined to achieve extremely tight tolerances, ensuring sharpness and a long lifespan.
- Ejector Sleeves: Used to position and eject parts from the mould smoothly, preventing product deformation.
- Hardness: After heat treatment, the material achieves a stable hardness (typically HRC 58-62°), allowing the components to withstand high pressure and friction during continuous operation.
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 the manufacturing of household appliances, automotive parts, and precision machinery.

Product Advantages

Superior Durability: With high-quality steel materials, the components resist repetitive force and pressure during production, 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.
Customization Service: We provide a custom manufacturing service from design and mold development to mass production, ensuring the product perfectly matches the client's blueprints and intended use.

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: 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 the product code, weight, dimensions, and handling instructions.
Storage Instructions: We recommend storing the products in a dry, cool environment, away from high humidity and corrosive chemicals.
