The detail information of product

VINACNC - Expert in S45C Ejector Pins for Maximizing Molding Efficiency

In the mould industry, the ejector pin is a core component that determines the precision and efficiency of the part ejection process. VINACNC is proud to supply high-quality S45C ejector pins, with a hardness of HRC 45-50°, ensuring reliable performance while providing a perfect balance of strength and flexibility. Our products are designed to maximize molding efficiency and withstand the rigors of continuous industrial operations.

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. This material is 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 of HRC 45-50°, 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 plastic injection molds and stamping die systems. Their primary function is to smoothly and precisely eject the cooled product from the mold cavity, preventing product damage and mold sticking.

Product Advantages

Optimal Balance of Strength and Flexibility: The hardness of HRC 45-50° provides a perfect balance, making the ejector pin strong enough to withstand force while flexible enough to resist breaking.
Maximize Molding Efficiency: The smooth operation and precise alignment of the ejector pins help to reduce the molding cycle time, enhancing overall production efficiency.
Absolute Precision: Dimensions are strictly controlled down to the micrometre level, ensuring the ejector pin operates in perfect conjunction with the mold, minimizing the risk of plastic leakage and product defects.
Reliable Performance at an Affordable Price: By using cost-effective S45C material and an optimized production process, we can offer products at a very competitive price without compromising on performance or reliability.

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 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.
