VINACNC - High-Precision and Durable SKD61 Ejector Sleeves

In the mould industry, the ejector sleeve is a core component that determines the precision and efficiency of the part ejection process. VINACNC is proud to supply SKD61 ejector sleeves with high hardness and tight tolerances, ensuring superior performance and durability even under harsh production conditions. Our products are always in-stock, ready to meet your needs immediately.

Technical Specifications, Materials, and Applications

Material: The product is 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 (typically HRC 48-54°), allowing the ejector sleeve to withstand high pressure and friction during continuous operation.
- Precision: The product is machined with extremely tight inner and outer 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 sleeve.
Applications: SKD61 ejector 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 sleeves can withstand repetitive force and pressure during production, extending the mould's lifespan.
Absolute Precision: Dimensions are strictly controlled down to the micrometer level, ensuring the ejector sleeves operate in perfect conjunction with the core pin, 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.
Competitive Wholesale Price: Thanks to our optimized and efficient production process, we can offer products at a wholesale price directly from the factory.

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 inner diameter, outer 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.
Mould Trial Run: We conduct a trial run on a real injection molding machine to evaluate the quality of the sample parts and ensure stable mold operation.

Packaging and Storage Process

Cleaning and Rust Prevention: The sleeves are cleaned and coated with a specialized anti-rust oil to protect their precision surfaces.
Secure Packaging: The products are carefully packed in a rigid plastic box or a cardboard crate 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.
