The Tungsten Carbide Piston Sleeve is a high-performance component engineered for extreme operating conditions, widely used in high-pressure plunger pumps, hydraulic systems, and precision injection molding equipment. Manufactured from high-purity tungsten carbide through precision sintering and grinding processes, it combines ultra-high hardness, exceptional wear resistance, and excellent corrosion resistance.

• Exceptional Wear Resistance, Extended Service Life: With a hardness exceeding HRA 90, the tungsten carbide material offers wear resistance more than 20 times greater than traditional chrome steel tubes.
• Ultra-High Pressure Resistance, Reliable Stability: Featuring a compressive strength over 3000 MPa, it withstands extreme system pressures and frequent impact loads.
• Low Friction Coefficient, Energy Efficient: The surface achieves an ultra-smooth finish of Ra ≤ 0.1 μm, reducing friction against sealing elements.
• Superior Corrosion Resistance: Resistant to acidic, alkaline, and high-salinity media, suitable for corrosive environments.

• High-Pressure Plunger Pumps: Piston sleeves in hydraulic systems for oil and mining industries
• Precision Injection Molding Machines: Guide sleeves in injection units
• Chemical Metering Pumps: Core components for corrosion-resistant fluid handling
• Aerospace: Critical wear-resistant components in hydraulic actuators

We utilize German imported sintering equipment and Japanese ultra-precision grinding technology to ensure every piston sleeve delivers:

• Zero-Defect Bore: Inner wall free from micro-porosity
• Full Customization: Support for non-standard ID/OD/length design
• Comprehensive Quality Control: Adherence to ISO 9001 and GJB standards

Let our professional engineers help you select the optimal piston sleeve configuration to break through equipment life limitations!
