16mm Diameter 40Cr & SKD61 Ejector Pins In Stock, Silver Gray Mould Part Accessories, RTS

In the mould industry, ejector pins are a core component that determines the precision and efficiency of the part ejection process. VINACNC is proud to supply 40Cr and SKD61 ejector pins with a diameter of 16mm, along with high hardness and tight tolerances, ensuring superior performance and durability even under harsh production conditions. Our products are in stock and ready to ship (RTS) for immediate delivery.

Technical Specifications, Materials, and Applications

• Materials: The products are crafted from high-quality tool steels:

  • 40Cr Steel: A high-quality alloy steel with good strength and hardness after heat treatment, often used for ejector pins.

  • SKD61 Steel (JIS): A widely used tool steel known for its hardness, strength, and good heat resistance, suitable for plastic injection and die-casting moulds.

• Technical Properties:

  • Dimensions: The pins have a diameter of 16mm. These dimensions can be customized according to customer requirements.

  • Color: Silver gray.

  • Hardness: After heat treatment, the materials achieve a stable hardness (typically around HRC 45-54°), allowing the pins 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 material leakage, and guaranteeing the accuracy of the final product.

• Applications: 40Cr and SKD61 ejector pins 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 steel and advanced heat treatment processes, our ejector pins can withstand repetitive force and pressure during production, 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: The smooth operation helps to reduce the molding cycle time and enhances overall production efficiency.

• In-Stock & Ready to Ship: 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

1. Hardness Test: We use a professional hardness tester to verify the hardness of the heat-treated material, ensuring it meets technical specifications.

2. Dimensional and Tolerance Check: We use a Coordinate Measuring Machine (CMM) or other high-precision measuring instruments to check the diameter, length, and concentricity.

3. Surface Inspection: We use a surface roughness tester and visual inspection to ensure there are no cracks, scratches, or other defects.

4. Functionality Test: The components are test-fitted with related parts to ensure a perfect fit and smooth operation.

Packaging and Storage Process

1. Cleaning and Rust Prevention: The components are cleaned and coated with a specialized anti-rust oil to protect their precision surfaces.

2. Secure Packaging: Products are carefully packed in rigid plastic boxes or cardboard crates with foam to prevent damage during transport.

3. Information Labeling: The packaging is clearly labeled with the product code, weight, dimensions, and handling instructions.

4. Storage Instructions: We recommend storing the products in a dry, cool environment, away from high humidity and corrosive chemicals.
