SKD61 Ejector Pins: The Optimal Solution for High-Temperature Plastic Molds

The detail information of product

In-Stock SKD61 Ejector Pin & Die Thimble (HRC50 Hardness) for Plastic Molds

In the mould 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 die thimbles with a controlled hardness of HRC50° and tight tolerances, ensuring superior performance and durability even under harsh production conditions. Our products are available at a competitive factory price and are always in stock.

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 die thimbles 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

Competitive Factory Price: With our optimized and efficient production process, we can offer products at a factory-direct price, helping clients reduce intermediary costs and increase profits.
Superior Durability: By using high-quality SKD61 steel and advanced heat treatment processes, our ejector pins and die thimbles can withstand 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.
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 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.
