Casting polyurethane wheel process flow
-
01
Design mold
- Design drawings and silicone molds according to customer requirements. Pay attention to details when demolding.
-
02
Clean wheel core
- Use a detergent to remove oil stains, residual rubber and other debris on the surface of the wheel core.
-
03
Grinding and sandblasting
- Grind and sandblast the surface of the roller core to increase the bonding between the wheel core surface and the polyurethane coating.
-
04
Raw material preparation
- According to the performance requirements of the wheel, prepare polyurethane raw materials such as high load, high and low temperature resistance, anti-static, and traceless.
-
05
Casting polyurethane
- Rotate and cast on the surface of the wheel core that has been pre-coated with adhesive to make the wheel core and the polyurethane colloid more firmly and fully bonded to avoid bubbles.
-
06
Vulcanization of polyurethane wheels
- After vulcanization, the wheel core is tightly combined with the colloid, and the PU rubber-coated wheel can be demolded after curing.
-
07
Finishing treatment
- Turn and remove burrs according to the size and shape required by the drawing, and use a CNC grinder for mirror polishing as needed.
-
08
Packing and delivery
- After the quality inspection is completed, the corresponding quality inspection report, raw material certificate and delivery details will be issued, and then carefully packed and shipped.
