Drawing and working environment are usually supplied by customers. Pepsen technicians select the appropriate polyurethane formulation for coating processing according to the requirements of color, size, hardness and working environment. The processing of polyurethane rubber-coated wheels needs to go through the following steps. Technological process:

1. Cleaning the iron core provided by customers: if it is a new core, the oil stain on the surface of the iron core should be cleaned with detergent; if it is an old core, the glue coating on the outer layer of the old should be removed, and the remaining glue on the surface of the iron core should be cleaned with detergent.

2. Roughening the surface of the core: Roughening the surface of the core to increase the bonding area between the surface of the core and the glue coating.

3. Sandblasting: Sandblasting the roughly treated core. Sand with different properties will be chose to sandblast core with different material. Sandblasting is to make the surface more rough, and the glue and iron core bond better after coating.

4. Gluing: Gluing the core after the above treatment according to customer's requirements.

5. Vulcanization of rubber coated wheel: The rubber roll after vulcanization generally needs 12-24 hours of vulcanization time. After vulcanization, the iron core of rubber roll will be strongly bonded with the rubber wrapping and the rubber coated wheel will be formed.

6. Rubber-coated wheel processing: according to the size and shape of customer requirements to process, some customers have higher requirements on the surface of rubber wheel, need to use lathe for processing and forming.

After the above six processes, the polyurethane coated wheel is completed.
