Ultra-Precision Tungsten Carbide Cylinder Sleeve Plunger Rod Industrial Tools

In extreme high-pressure working conditions, traditional metal materials often fail to meet stringent performance requirements. Our tungsten carbide cylinder sleeve plunger rod is specifically developed for ultra-high pressure environments above 450MPa. Utilizing innovative YG6X nano tungsten carbide material and prepared through specialized powder metallurgy processes, it ensures exceptional deformation resistance and dimensional stability.

Core Performance Advantages

• Extreme Pressure Resistance: Tested withstand capacity up to 600MPa
• Ultra-Precise Fit: Clearance between plunger and sleeve ≤0.002mm
• Exceptional Precision: Cylindricity ≤0.001mm, straightness ≤0.001mm/100mm
• Ultra-Smooth Surface: Ra0.05μm super-mirror finish

What does this level of machining precision mean? It equates to a straightness deviation of no more than 1/80th of a hair's diameter over a 1-meter-long rod.

Material Innovation

We have innovatively incorporated rare earth element modifiers into the traditional tungsten carbide formulation. This breakthrough maintains a 94% high-hardness WC phase while improving the uniformity of the cobalt phase distribution by 40%, effectively addressing micro-plastic deformation under high pressure. After specialized heat treatment, the product's residual stress is controlled within 50MPa, far below the industry standard of 200MPa.

Precision Machining Process

The entire manufacturing process is completed in a constant-temperature, constant-humidity Class 10,000 cleanroom. We employ a three-stage composite process of "diamond turning + ultrasonic grinding + ion polishing." The most critical ultra-precision machining phase utilizes a self-developed hydraulic suspension fixture system, eliminating micro-deformation caused by traditional mechanical clamping.

The quality inspection phase is exceptionally rigorous: Each product undergoes 12 inspection procedures, including coordinate measuring machine (CMM) measurements, white light interferometer surface analysis, and X-ray residual stress testing. We have invested in imported inspection equipment worth millions to ensure accurate and reliable data.
