VINACNC - Expert in High-Precision Round Head Ejector and Punch Pins for Moulds

In the mold and stamping industry, ejector pins and punch pins are core components that determine the precision and efficiency of the production process. VINACNC is proud to supply high-quality round head ejector and punch pins 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 good toughness after heat treatment.
Technical Properties:
- Round Head: The round head design minimizes friction during punching and allows for easy positioning, making it suitable for press dies.
- DIN Standard: Products comply with the DIN (German Industrial Standard), ensuring compatibility and high quality.
- 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: 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.
Applications: Round head ejector and punch pins are indispensable components in plastic injection molds and stamping dies for part ejection and hole punching. They are widely used in industries producing automotive parts, electronic device housings, and precision machinery.

Product Advantages

Superior Durability and Performance: With high-quality materials, the ejector and punch pins resist repetitive force and pressure, 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 material leakage and product defects.
Optimized Efficiency: The smooth operation helps to reduce the cycle time and enhances overall production efficiency.
International Standard Compliance: Manufacturing according to DIN standards ensures compatibility and high quality, making it easier for clients to integrate our components.

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.
