The detail information of product

VINACNC - Expert in OEM Punch Pins and Ejector Pins for Household Appliance Moulds

In the household appliance manufacturing industry, creating plastic parts requires moulds with exceptional precision and durability. Punch pins and ejector pins are core mould components that determine the accuracy and quality of the final product. VINACNC is proud to offer custom OEM punch pin and ejector pin manufacturing services using premium materials such as HSS, SUS, Tungsten steel, M2, and SKD-11, meeting the most stringent standards for household appliance moulds.

Technical Specifications, Materials, and Applications

Materials: The components are crafted from high-quality tool steels:
- M2 High-Speed Steel (HSS) and SKD-11: Known for their hardness, wear resistance, and good toughness, ideal for punching and ejector pins.
- Stainless Steel (SUS): Often used in applications requiring corrosion resistance.
- Tungsten Steel: Extremely high hardness and wear resistance, suitable for applications demanding maximum durability.
Technical Properties:
- Hardness: After heat treatment, the materials achieve 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 mould, preventing plastic leakage, and guaranteeing the accuracy of the final product.
- Surface Finish: The surface is specially treated to achieve high smoothness, which reduces friction and extends the lifespan of the pins.
Applications: Punch pins and ejector pins are indispensable components in injection moulds for producing household appliance parts, from housings, handles, and buttons to internal functional components.

Service Advantages

Superior Durability: With high-quality materials, the components resist repetitive force and pressure during production, 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 moulding cycle time and enhances overall production efficiency.
Flexible OEM/ODM Service: We provide custom manufacturing services from design and mould 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 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: We recommend storing the products in a dry, cool environment, away from high humidity and corrosive chemicals.
