The detail information of product

High-Precision Nitrided H13 Ejector Pins and Guide Pins

In the mould industry, ejector pins and guide pins are core components that determine the precision and efficiency of the part ejection process. VINACNC is proud to supply H13 ejector pins and guide pins with high hardness and tight tolerances. These components are treated with an advanced Nitriding heat treatment to ensure superior performance and durability even under harsh production conditions.

Technical Specifications, Materials, and Applications

Material: The products are crafted from high-quality H13 tool steel (AISI/SAE), a steel widely used for its hardness, strength, and good heat resistance.
Technical Properties:
- Nitriding 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.
- High Surface Hardness: After Nitriding, the material achieves a stable and high surface hardness (typically HRC 52°), allowing the components to withstand continuous high pressure and friction.
- Precision: Products are machined with extremely tight diameter tolerances, ensuring a perfect fit with the mould, preventing material leakage, and guaranteeing the accuracy of the final product.
Applications: Nitrided H13 ejector pins and guide 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: The hard surface layer created by the Nitriding process helps the pins and guides resist wear and deformation from repetitive friction and pressure.
Absolute Precision: Dimensions are strictly controlled down to the micrometre level, ensuring the components operate in perfect conjunction, minimizing the risk of material 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 specially treated surface 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 surface and core 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.
