Rotational Moulding is a process of forming hollow plestic products. Firstly put the plastic powder into the mold and then heated and rotated along two vertical axes. The powder in the mold is melted and adhered onto the mold inner surface, then cooling down the mold and take out the product when it reaches a correct lamparature

Compare to the extrusion, injection and blow molding processes, which are often used in plastic moiding The rotational moulding process is more suitable for the production of large, medium or complex plastic products, The products have almost no internal stress to ensure a very long service life.
