The detail information of product

VINACNC - High-Precision S45C Ejector and Punching Pins

In the mould industry, ejector pins and punching pins are core components that determine the precision and efficiency of the manufacturing process. VINACNC is proud to supply S45C ejector and punching pins with a specific dimension of 70x10mm, along with high hardness and tight tolerances, ensuring superior performance and durability even under harsh production conditions.

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:
- Dimensions: Length 70mm, diameter 10mm. These dimensions can be customized according to customer requirements.
- Hardness: After heat treatment, the material achieves a stable hardness (typically HRC 20-30°), allowing the pins to withstand high pressure and friction during continuous operation.
- Precision: The products are machined with extremely tight diameter tolerances, ensuring a perfect fit with the mold, preventing material 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 operation, and extends the lifespan of the components.
Applications: S45C Ejector pins and punching pins are indispensable components in plastic injection molds and stamping dies.
- Ejector Pins: Eject the cooled product from the mold cavity smoothly and precisely, preventing product damage and mold sticking.
- Punching Pins: Used for punching holes in sheet metal or plastic parts during the stamping process.

Product Advantages

Reasonable Pricing: By using cost-effective S45C material and an optimized production process, we can offer products at a very competitive price.
Superior Durability: With optimized hardness, the pins resist repetitive force and pressure during production, extending the mould's lifespan.
Absolute Precision: Dimensions are strictly controlled down to the micrometer 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 cycle time and enhances overall production efficiency.

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.
