VINACNC - Expert in Carbonitrided SKD-61 Ejector Pins for Molds

In the mold industry, the ejector pin is a core component that determines the precision and efficiency of the part ejection process. VINACNC is proud to supply SKD-61 straight ejector pins with an advanced Carbonitriding heat treatment process. This ensures a tightly controlled surface and core hardness, providing superior performance and durability even under extreme production conditions.

Technical Specifications, Materials, and Applications

Material: The product is crafted from SKD-61 tool steel (JIS), a high-quality steel widely used for its hardness, strength, and good heat resistance.
Technical Properties:
- Carbonitriding Heat Treatment: This advanced process enhances the surface hardness and wear resistance of the steel. The resulting hard surface layer has an ideal depth, while the core maintains ductility to resist cracking under impact.
- Hardness: After treatment, the material achieves a stable and high surface hardness, allowing the ejector pin to withstand continuous high pressure and friction.
- Precision: The product is machined with extremely tight diameter tolerances, ensuring a perfect fit with the mold, preventing plastic leakage, and guaranteeing the accuracy of the final product.
Applications: Carbonitrided SKD-61 straight ejector pins are indispensable components in plastic injection 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: The hard surface layer created by the Carbonitriding process helps the ejector pin resist wear and deformation from repetitive friction and pressure.
Absolute Precision: Dimensions are strictly controlled down to the micrometer level, ensuring the ejector pin operates in perfect conjunction with the mold, 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.
Crack Resistance: With the core's ductility preserved, the ejector pin has better crack resistance compared to other heat treatment methods.

Post-Machining Product Inspection Process

Hardness Test: We use a professional hardness tester to verify the surface and core hardness of the Carbonitrided 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 ejector pin is test-fitted with related components to ensure a perfect fit and smooth operation.

Packaging and Storage Process

Cleaning and Rust Prevention: The pin is cleaned and coated with a specialized anti-rust oil to protect its precision surfaces.
Secure Packaging: The product is 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 product in a dry, cool environment, away from high humidity and corrosive chemicals.
