VINACNC - High-Precision 65Mn Ejector Pins and Sleeves at Factory Price

In the mold industry, ejector pins and ejector sleeves are critical auxiliary components that determine the precision and efficiency of the part ejection process. VINACNC proudly offers professional machining services for 65Mn metal-based ejector pins and sleeves, ensuring superior performance and durability even under harsh production conditions. Our products are available at a competitive factory price and are always in stock for immediate delivery.

Technical Specifications, Materials, and Applications

Material: The products are crafted from 65Mn spring steel—a high-quality carbon alloy steel known for its high hardness and excellent wear resistance after heat treatment.
Technical Properties:
- Hardness: After heat treatment, the material achieves a stable hardness of HRC 50°±2°, allowing the components 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 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 components.
Applications: 65Mn ejector pins and sleeves 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

Competitive Factory Price: Thanks to our optimized and efficient production process, we can offer products at a factory-direct price, helping clients reduce intermediary costs and increase profits.
Superior Durability: With a hardness of HRC 50°±2°, these components resist repetitive force and pressure during production, extending the mould's lifespan.
Absolute Precision: Dimensions are strictly controlled down to the micrometre level, ensuring the components operate in perfect conjunction with the mold, minimizing the risk of plastic leakage and product defects.
Optimized Performance: The smooth operation helps to reduce the molding cycle time and enhances overall production efficiency.
In-Stock Availability: With a large inventory of standard sizes, we can quickly fulfill orders, ensuring our clients' production processes are not interrupted.

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.
