Durable FDAC Ejector Sleeves: The Optimal Solution for High Temperature Moulding

The detail information of product

FDAC Ejector Sleeves are Ideal for High-Temperature Injection Molding Processes

In the mold industry, especially for plastic injection and die-casting molds, components must withstand constant pressure, high temperatures, and friction. VINACNC is proud to offer FDAC Ejector Sleeves—a groundbreaking solution that resists wear and deformation even under the most extreme conditions, ensuring maximum performance and durability for your molds. This product is particularly ideal for high-temperature injection molding processes.

Technical Specifications, Materials, and Applications

Material: The product is manufactured from FDAC steel, a high-quality die-casting mold steel produced by Daido Steel (Japan). It's an improved version of H13-grade tool steel, optimized for superior thermal crack resistance and hardness at high temperatures.
Technical Properties:
- High Core Hardness: After heat treatment, FDAC steel achieves a uniform core hardness of 38-42 HRC, enabling the ejector sleeve to withstand significant impact forces during the ejection process.
- Superior Surface Hardness: The surface is nitrided or coated with a wear-resistant layer, reaching a hardness of HV 900-1100, which effectively reduces friction and wear.
- Precise Tolerances: The product is machined with an extremely tight outer diameter tolerance, typically -0.01/-0.02mm, ensuring a perfect fit with other mold components.
Applications: FDAC Ejector Sleeves are essential for plastic injection and die-casting molds producing complex, high-durability parts such as automotive components, electronic device housings, and industrial products. Their resistance to heat and wear makes them particularly suitable for molds operating at high temperatures or with fast production cycles.

Product Advantages

Superior Durability: The combination of high core hardness and a superior surface layer allows FDAC ejector sleeves to resist wear and deformation from repetitive friction and pressure, especially in extreme conditions.
Extended Mold Lifespan: The ability to endure conditions like high temperatures and strong ejection forces extends the lifespan of the ejector sleeves, which in turn reduces maintenance and replacement costs for the entire mold.
Optimized Production Cycles: Thanks to their high precision and smooth operation, parts are ejected from the mold quickly and efficiently, significantly shortening the production cycle time.
High Reliability: FDAC steel is a proven and trusted material in industries that demand high precision and safety, providing absolute reliability for the manufacturing process.

Post-Machining Product Inspection Process

Material and Hardness Check: We use a spectrometer to confirm the material composition and a hardness tester (HRC/HV) to verify the quality of the heat treatment.
Dimensional and Tolerance Check: A Coordinate Measuring Machine (CMM) or other high-precision measuring devices are used to ensure all critical dimensions comply with the design drawings.
Surface Inspection: We use a surface roughness tester and perform a visual inspection to ensure there are no cracks, scratches, or other defects.
Functionality Test: The ejector sleeve is test-fitted with related components to ensure a perfect fit and smooth operation.

Packaging and Storage Process

Cleaning and Rust Prevention: The product is thoroughly cleaned and coated with a specialized anti-rust oil to protect its precision surfaces.
Secure Packaging: Each sleeve is individually packed in a plastic bag or a hard plastic box, then placed in a sturdy carton with shock-absorbing cushioning.
Information Labeling: The package is clearly labeled with product information, weight, dimensions, and handling instructions.
Storage Instructions: We recommend storing the product in a dry, cool environment, away from high humidity and corrosive chemicals.
