VINACNC - S45C Ejector Pins for High-Performance Automotive Molds

In the automotive industry, plastic parts require high precision and the ability to perform reliably under harsh conditions. The ejector pin is a core component of the injection mold, determining the accuracy and quality of the final product. VINACNC is proud to supply premium S45C ejector pins, designed to guarantee consistent quality and high performance in the production of automotive parts.

Technical Specifications, Materials, and Applications

• Material: The product is crafted from S45C carbon steel (JIS), a common steel known for its good hardness and mechanical strength after heat treatment. It's an ideal choice for applications that require a balance between hardness and toughness.

• Technical Properties:

  • Hardness: After heat treatment, the material achieves a stable hardness (typically HRC 20-30°), allowing the ejector pin to withstand high pressure and friction during continuous operation.

  • Precision: The product is 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 pin.

• Applications: S45C ejector pins are indispensable components in injection molds producing automotive parts, from interior components and light housings to technical plastic parts in engines and electrical systems.

Product Advantages

• Guaranteed Consistent Quality: With our strictly controlled manufacturing process from material selection to machining, our ejector pins ensure that every plastic part produced is of uniform quality.

• High Performance: Optimized hardness and a smooth surface allow the ejector pin to operate efficiently, reducing friction, which in turn shortens the molding cycle time and enhances production output.

• Superior Durability: The S45C ejector pin resists repetitive force and pressure during production, extending the mold's lifespan.

• Reasonable Price: By using cost-effective S45C material and an optimized production process, we can offer products at a very competitive price.

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 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 pin is cleaned and coated with a specialized anti-rust oil to protect its precision surfaces.

• Secure Packaging: The product is 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 product in a dry, cool environment, away from high humidity and corrosive chemicals.
