4" Red Polyurethane Wheel

During the production and use of 4 "Red Polyurethane Wheels, the following measures can be taken to avoid the generation of bubbles, cracks, and extend their service life:
Avoid generating bubbles during the production process:
Raw material processing:
Ensure that the polyurethane raw materials are fully dried, free of moisture and other impurities.
Use vacuum degassing equipment to degas the raw materials.
Mixing process:
Use high-speed stirring and efficient mixing equipment to ensure thorough and uniform mixing of components A and B.
Control the mixing speed and time to avoid mixing too quickly and introducing air.
Pouring process:
Adopting low-pressure casting technology to avoid the generation of bubbles.
The temperature of the mold during pouring should be controlled appropriately, not too high or too low, to reduce the generation of bubbles.
Mold design:
Mold design should ensure smooth pouring system, reduce eddy currents and dead corners.
The surface of the mold should be smooth, undamaged, and conducive to gas escape.
Demoulding and post-processing:
Timely heat treatment after demolding can eliminate internal stress and also facilitate the escape of bubbles.

Our 4 "Red Polyurethane Wheel is widely used in multiple industries due to its unique material properties. Has the following advantages:
1. Wear resistance:
Polyurethane materials have extremely high wear resistance and can maintain good performance even under heavy loads and high-speed operation conditions.
2. Compression resistance:
Polyurethane wheels can withstand significant compression deformation and are not easily deformed even under long-term heavy loads.
3. Tear resistance:
Polyurethane wheels have good tear resistance and are not easily damaged even under sharp object impact.
4. Chemical resistance:
Polyurethane wheels have good resistance to various chemicals and are not easily corroded.
5. Shock absorption performance:
Polyurethane materials have good shock absorption properties and can provide smoother operation on uneven surfaces.
6. Low rolling resistance:
Polyurethane wheels have lower rolling resistance, which can reduce energy consumption and improve efficiency.
