Wonderful sharing | An introduction to the rotational molding process that cannot be missed

Rotomolding, also known as rotational molding, rotational molding, rotational casting, and rotoforming, is a process in which plastic material is placed in a mold. The mold is then rotated along two perpendicular axes and heated. Under the influence of gravity and heat, the plastic material in the mold gradually and evenly spreads and melts over the entire surface of the mold cavity, forming it into the desired shape. The final product is then cooled and solidified. There are many different processes for processing plastics and their composite materials. In addition to the more common extrusion, injection molding, and blow molding, rotational molding is also a method for producing plastic products. Currently, the rotomolding industry is developing rapidly internationally, while in China, due to various factors, such as slow processing cycles and material limitations, the industry is developing more slowly than other plastic molding industries. It is important to note that the production efficiency of rotomolded products is very low. The production time for a single product, including forming, cooling, and mold assembly and disassembly, generally ranges from 30 to 60 minutes. Therefore, the number of products produced depends on the number of molds, and multiple molds can be rotated simultaneously on the machine.
