The Direct Sales Standard Or Customized Wear Resistant Long Working Life SKD 61 Ejector Sleeve is a robust solution for press die applications, designed to withstand high mechanical stress and thermal cycles. Engineered from SKD61 hot work tool steel, this ejector sleeve ensures reliable part ejection in hot forging and stamping dies, minimizing downtime and maintenance costs.
Heat Resistance Material: SKD61 steel (HRC48-52) with vacuum quenching, operating reliably up to 600°C and resisting thermal fatigue in hot forging processes.
Wear-Resistant Design: Internal surface treated with plasma nitriding (depth 0.3-0.5mm), reducing abrasion from aluminum and magnesium alloy forgings by 40%.
Precision Fit: Clearance control between ejector pin and sleeve ≤0.005mm, preventing metal ingress and ensuring smooth ejection in high-pressure forging dies.
Customization Capability: Available in diameters 10-100mm and lengths 100-1000mm, with optional cooling channels for rapid heat dissipation in continuous forging lines.
Surface Treatment Options: TiCN coating (hardness HV2500) for extreme wear resistance or electroless nickel plating for corrosion-prone environments.
Critical for press die operations, this ejector sleeve is used in:
Hot Forging Dies: Ejection of automotive transmission gears, engine valves, and connecting rods from high-temperature forgings (1200°C workpiece temperature).
Stamping Dies: Support for heavy-duty stamping of steel plates (3-10mm thickness), ensuring consistent ejection in low-carbon steel and alloy steel processing.
Die Casting Dies: Heat-resistant ejection of aluminum alloy parts in high-pressure die casting, compatible with release agents and thermal cycling.
Industrial Forging: Reliable performance in large-scale forging of machinery components like flanges, couplings, and heavy-duty fasteners.
Thermal Stability: Patented heat treatment process reduces dimensional change to ≤0.02% after 10,000 thermal cycles, critical for maintaining die precision.
Engineering Collaboration: Work with customers to optimize sleeve geometry for specific forging pressures (up to 5000 tons), reducing ejection failure rates by 70%.
Cost Efficiency: 2x longer service life than standard ejector sleeves, lowering total cost of ownership through reduced replacement frequency.
Global Certification: Compliant with AISI H13 and JIS SKD61 standards, ensuring compatibility with international die designs and material specifications.
