The detail information of product

VINACNC - High-Precision and Durable In-Stock 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 in-stock SKD61 ejector sleeves with a tightly controlled surface and core hardness, ensuring superior performance and durability even under harsh production conditions. Our products are readily available 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 advanced heat treatment, the material achieves a stable surface hardness of HRC 60°±2° and a core hardness of HRC 38°±2°. This dual-hardness structure provides superior wear resistance on the surface while maintaining ductility in the core to prevent cracking under impact.
- 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: Thanks to the controlled dual-hardness structure, the ejector sleeve resists 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.
In-Stock Availability: With a large inventory of standard sizes, we can quickly fulfill orders, ensuring our clients' production processes are not interrupted.

Post-Machining Product Inspection Process

Hardness Test: We use a professional hardness tester to verify the surface and core 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.
