VINACNC - Expert in Precision Ejector Pins and Sleeves for International Standards

In the mould industry, ejector pins and ejector sleeves are core components that determine the precision and efficiency of the part ejection process. VINACNC is proud to supply high-precision ejector pins and sleeves that comply with international standards such as Misumi, DME, Hasco, and JIS, ensuring superior performance and durability.

Technical Specifications, Materials, and Applications

Materials: The products are crafted from high-quality tool steels such as SKD-61, SKH51, 65Mn, and 40Cr, depending on the specific application requirements.
Standards:
- Misumi: Ejector pins and sleeves are manufactured with high precision, meeting Misumi standards for easy replacement and integration into existing moulds.
- DME, Hasco: Compliance with DME and Hasco standards, two of the world's leading mould component suppliers, ensures high quality and compatibility.
- JIS: Products conform to Japanese Industrial Standards (JIS), guaranteeing quality and reliability.
Technical Properties:
- Straight Ejector Pins: A simple, common design suitable for many applications.
- Stepped Sleeves: A stepped design ensures precise positioning and focused ejection force.
- Precision: CNC machined with extremely tight diameter tolerances, ensuring a perfect fit with the mould.
Applications: 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

Superior Durability: With high-quality steel materials and advanced heat treatment processes, the 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, 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.
International Standard Compatibility: Compliance with Misumi, DME, Hasco, and JIS standards ensures high quality and easy integration for clients.

Post-Machining Product Inspection Process

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.
Functional 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 product information, including product code, dimensions, and handling instructions.
Storage: We recommend storing products in a dry, cool environment, away from high humidity and corrosive chemicals.
