Rotomolding scrap grinding

CMG S.p.A. manufactures granulators and shredders for grinding up rotomolding scraps.

Rotomolding is an industrial process for creating hollow items, usually of large size, in a single piece without welding. Plastic powder is poured into a hollow mold which is heated to a very high temperature to melt the plastic. The melted plastic is distributed over the internal walls of the mold by centrifugal force to form an even layer and make the end product.

This process makes end products from a wide range of technopolymers and other thermoplastic resins, the most common of which are:

- polyethylene (PE)
- polypropylene (PP)
- polyvinyl chloride (PVC )
