VINACNC is proud to supply brand new ejector pin and sleeve sets with high hardness and tight tolerances, ensuring superior performance and durability. Our products are always in stock and ready to ship to meet your needs immediately.

Technical Specifications, Materials, and Applications

Material: The products are crafted from high-quality tool steels such as SKD-61, 65Mn. These materials are known for their high hardness and excellent wear resistance after heat treatment, ensuring a long lifespan.
Technical Properties:
- Hardness: After heat treatment, the material achieves a stable hardness (typically HRC 50°±2° for 65Mn or HRC 48-52° for SKD-61), allowing the components to withstand high pressure and friction during continuous operation.
- Precision: The products are machined with extremely tight diameter tolerances, ensuring ideal concentricity and a perfect fit with the core pin. This prevents plastic leakage and guarantees the accuracy of the final product.
- Surface Finish: The surface is specially treated to achieve high smoothness, which reduces friction, ensures a seamless ejection process, and extends the lifespan of the components.
Applications: The ejector pin and sleeve set is an indispensable component in plastic injection molds and stamping die systems. Its primary function is to smoothly and precisely eject the cooled product from the mold cavity, preventing product damage and mold sticking.

Product Advantages

In-Stock and Ready to Ship: With a large inventory, we can quickly fulfill orders, ensuring our clients' production processes are not interrupted.
Superior Durability: Thanks to high-quality materials and advanced heat treatment processes, these 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 plastic leakage and product defects.
Optimized Performance: The smooth operation helps to reduce the molding cycle time and enhances overall production efficiency.

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.
Functionality 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.
