VINACNC - High-Quality and Hot-Selling SKD61 Ejector Pins and Sleeves

In the mold industry, the ejector pin and die thimble (ejector sleeve) are core components that determine the precision and efficiency of the part ejection process. VINACNC is proud to supply high-quality SKD61 ejector pins and sleeves with a controlled hardness of HRC50° and tight tolerances, ensuring superior performance and durability even under harsh production conditions. This product is one of our hot-selling solutions, trusted by many clients.

Technical Specifications, Materials, and Applications

Material: The products are crafted from high-quality SKD61 tool steel (JIS), a widely used steel known for its hardness, strength, and good heat resistance.
Technical Properties:
- Hardness: After heat treatment, the material achieves a stable hardness of HRC50°, allowing the pins and sleeves to withstand high pressure and friction during continuous operation.
- Precision: The products are machined with extremely tight diameter tolerances, ensuring a perfect fit with the mold, 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, ensures a seamless ejection process, and extends the lifespan of the components.
Applications: SKD61 Ejector pins and sleeves are indispensable components in plastic injection molds and die-casting molds for complex, high-durability parts such as automotive components, electronic device housings, and industrial products.

Product Advantages

Superior Durability: By using high-quality SKD61 steel and advanced heat treatment processes, our ejector pins and sleeves can withstand 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 plastic leakage and product defects.
Optimized Performance: The smooth operation helps to reduce the molding cycle time and enhances overall production efficiency.
High Quality and Durability: Our products are manufactured under a strict quality control process, from material selection to heat treatment and final machining, ensuring consistency and reliability.

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.
