H13 Ejector Pins: The Optimal Solution for Die Casting & High-Temperature Moulds

The detail information of product

VINACNC - Expert in High-Temperature Resistant, Customizable H13 Ejector Pins

In the mould industry, especially for high-pressure die-casting and injection moulding that operate at high temperatures, the ejector pin is a core component that determines the precision and efficiency of the ejection process. VINACNC proudly supplies imported H13 ejector pins with an advanced vacuum heat treatment process. These products are high-temperature resistant and customizable in multiple specifications, ensuring superior performance and durability even under the most demanding 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:
- Heat Treatment: We use a vacuum quenching process, which provides a uniform hardness and refined microstructure, typically achieving a hardness of HRC 48-52°.
- High Temperature Resistance: H13 steel maintains its hardness and strength at elevated temperatures, making it ideal for molds casting molten metals like aluminum and zinc.
- High Precision: The products are machined with extremely tight diameter tolerances, ensuring a perfect fit with the mold, preventing leakage of plastic or molten metal.
- Versatility: The ejector pins are customizable in multiple specifications for diameter, length, and other special features to fit various mold designs.
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: The ejector pins resist repetitive force and pressure during production, extending the mould's lifespan.
High Temperature Resistance: The ability of H13 steel to maintain its hardness and strength at high temperatures ensures stable and reliable operation in die-casting applications.
Absolute Precision: Dimensions are strictly controlled down to the micrometer level, ensuring the components operate in perfect conjunction, minimizing the risk of leakage and product defects.
Flexible Customization: We provide custom manufacturing services from design to production, ensuring the product perfectly matches the client's blueprints and intended use.

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: A Coordinate Measuring Machine (CMM) or other high-precision measuring devices are used 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 ejector pin is test-fitted with related components to ensure a perfect fit and smooth operation.

Packaging and Storage Process

Cleaning and Rust Prevention: The pins are cleaned and coated with a specialized anti-rust oil to protect their precision surfaces.
Secure Packaging: Products are carefully packed in a rigid plastic box or a cardboard crate 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.
