The detail information of product

VINACNC - Expert in High-Precision and Customizable SKD61 Ejector Pins and Sleeves

In the mould industry, ejector pins and ejector sleeves are core components that determine the precision and efficiency of the part ejection process. VINACNC is proud to supply customizable ejector pins and ejector sleeves from SKD61 steel with high precision and high hardness, ensuring superior performance and durability even under harsh production conditions.

Technical Specifications, Materials, and Applications

Material: The components are manufactured from high-quality SKD61 tool steel (JIS), a widely used steel known for its hardness, strength, and good heat resistance.
Technical Properties:
- Precision: Products are machined with extremely tight diameter tolerances, ensuring a perfect fit with the mould, preventing plastic leakage, and guaranteeing the accuracy of the final product.
- Hardness: After heat treatment, the material achieves a stable hardness (typically HRC 48-54°), allowing the components to withstand high pressure and friction during continuous operation.
- Customizable Features: We can customize features such as pin tip design, sleeve shape (straight, stepped, etc.), and surface coatings (e.g., Carbide Polishing or nitriding) to optimize performance for specific applications.
Applications: SKD61 Ejector pins and sleeves are indispensable components in plastic injection molds, die-casting molds, and stamping die systems. Their primary function is to smoothly and precisely eject the cooled product from the mold cavity, preventing product damage and mold sticking.

Product Advantages

Superior Durability: With optimized materials and heat treatment processes, these components resist repetitive force and pressure, 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: Customizable features and professional surface finishes help to reduce the molding cycle time and enhance overall production efficiency.
Custom OEM Service: We provide a custom manufacturing service 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.
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.
