Double Ejector Round Pin: The Optimal Solution for Plastic Injection Moulds

The detail information of product

VINACNC - Expert in H13 Ejector Pins and Rods with Strong Resistance

In the mould industry, ejector pins and ejector rods are core components that determine the precision and efficiency of the part ejection process. VINACNC is proud to supply H13 ejector pins and rods with high hardness and tight tolerances, designed to withstand strong compression and bending forces. This ensures superior performance and durability even under harsh production conditions.

Technical Specifications, Materials, and Applications

Material: The products are crafted from H13 tool steel (AISI/SAE), a high-quality steel widely used for its hardness, strength, and good heat resistance.
Technical Properties:
- Compression and Bending Resistance: After heat treatment, H13 steel achieves a stable hardness (typically HRC 48-52°), allowing the pins and rods to withstand high compressive and bending forces 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: H13 ejector pins and rods 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 hardness and compression/bending resistance of H13 material, these components 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 moulding cycle time and enhances overall production efficiency.
High Wear Resistance: The ultra-precise surface finish gives the components high wear resistance, allowing them to withstand millions of production cycles.

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.
