The 5 inch Heavy Duty Polyurethane Wheel combines the strength of the metal wheel core with the excellent properties of polyurethane material, and is very popular in industrial production.
To produce a high-quality 5 inch Heavy Duty Polyurethane Wheel , the following aspects need special attention:
1. The wheel core is usually made of steel or iron and is the load-bearing skeleton of polyurethane material. Before pouring polyurethane, the wheel core must be sandblasted to remove rust and increase surface roughness. Subsequently, specialized adhesive needs to be sprayed on the surface of the wheel core. This step is crucial as it ensures a strong bond between the polyurethane gel and the metal wheel core, preventing delamination or cracking during future use.
During the mixing and pouring process of polyurethane raw materials, it is necessary to ensure that the temperatures of the wheel core, mold, and polyurethane raw materials are close. If the temperature difference is too large, it will cause uneven curing speed of polyurethane, generate internal stress, and affect the service life of the finished product. In addition, when mixing the raw materials, they should be stirred slowly and evenly to avoid the formation of air bubbles. This step is crucial
3. Polyurethane raw materials are sensitive to temperature and humidity. It is recommended to keep the construction environment temperature above 5 ℃ and maintain ventilation and cleanliness in the work area to avoid dust and impurities affecting product quality. At the same time, strictly follow the material ratio and mixing process.
