Most thermoplastics and thermosets can be formed into products with a large cavity with Rotational molding process. Mould with thin metal walls are made in two pieces and is designed to rotate in two mutually perpendicular axes. Plastic powder that has been measured previously placed in a warm mold. Mould then heated in an oven usually large, while the mold is rotated in two axes. This process makes the powder pressed into a mold where the mold surface will heat the powder without melt. The types of products made with this process are tanks with a variety of sizes, trash, baket, housing, ball. The liquid polymer called plastisol (usually used vinyl plastisol) can also be used in slush molding process. Mold simultaneously heated and rotated. After contact with the wall of the mold material to melt and mold wall wrap. Products to be cold when it was still spinning and removed by opening the mold.
