Due to its good mechanical strength, wear resistance, impact resistance and low friction coefficient, HDPE (high-density polyethylene) sheets can be processed into a variety of structural and functional parts in the machinery industry, especially for corrosion-resistant, low-load, lubricated or sliding parts.
Typical mechanical parts that can be processed with HDPE sheets include:
- Wear-resistant sliding parts
Sliders/slide rails
Guide rail linings
Chain guide plates/chain guide grooves
Sliding gaskets/friction blocks
Applied to conveying equipment, packaging machinery, and automated guide structures. - Shaft accessories
Sleeves/bushings
Guide rings
Low-speed rotating parts
Suitable for environments that require low friction and high wear resistance, and can replace some bronze or nylon sleeves. - Gears
Small modulus plastic gears (low speed and light load)
Coupling gaskets
Rack segments
HDPE can be used as non-metallic light-load gears with low noise and smooth operation. - Structural support
Gaskets/support blocks
Pressure plates/fixing blocks
Connecting plates (insulating parts)
Used for isolation, support, and vibration resistance of mechanical structures. - Seals/gaskets
Flange gaskets
Mechanical buffer gaskets
Valve sealing base plates
The chemical stability of HDPE makes it suitable for low-pressure chemical seals. - Transmission & auxiliary components
Roller jackets
Drag chain support plates
Mechanical protection baffles
