High-Precision Ground H13 Ejector Pins with High Toughness and Breakage Resistance

In the mould industry, especially with complex and high-intensity moulds, ejector pins must have both high precision and exceptional toughness. VINACNC is proud to supply H13 ejector pins that are precision ground, have high toughness, and are resistant to breakage. This ensures maximum performance and durability for your complex moulds.

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:
- High Precision: The products are precision ground with extremely tight diameter tolerances, ensuring a perfect fit with the mold, preventing plastic leakage, and guaranteeing the accuracy of the final product.
- High Toughness and Breakage Resistance: After heat treatment, the material achieves a stable hardness (typically HRC 48-52°) while maintaining high toughness, allowing the pins to withstand strong pressure and impact without breaking.
- 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 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: With high-quality H13 material, the ejector pin resists 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.
Breakage Resistance: The high toughness of the material allows the ejector pins to withstand strong impacts and forces, minimizing the risk of damage during the production process.

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.
