What Is Rotational Molding?
Rotational molding is a molding process for manufacturing hollow plastic products.
In rotational molding, thermoplastic resin powder is placed into a mold and rotated in an oven. The powder melts and adheres to the inside of the mold, which is then cooled, and the product is removed. This molding method is used in the production of various products such as tanks, drums, buckets, cases, furniture, playground equipment, traffic signs, and outdoor lighting.
Rotational molding offers many advantages compared to other molding methods. Firstly, it allows for the production of products with complex shapes. It also enables the manufacture of large-sized products and is relatively cost-effective. Another characteristic feature is that it allows the use of materials that cannot be used in other molding methods such as injection molding or blow molding.
