Rotational
moulding are specialized machines which are used to process plastic into
different products. The process involves rotating the mold on axis and
heating it in the oven. The heat melts the plastic blend and helps it
take the shape of the mold. Unlike other molding processes, this does
not involve application of pressure on plastic thus ensuring stress free
product. The mold is then cooled by air or water in a separate cooling
station, finally the product so formed is de-molded. These roto moulding
machines manufacture right from small to gigantic plastic parts and
ensure superior finish of products.
Types of rotational moulds used
- Rectangular rotational moulds
- Circular rotational moulds
Advantage of Roto Moulding Machines
- Low investment in machine and moulds
- Uniform wall thickness of products
- Smooth surface finish
- Moulds can be light weight as no pressure is applied
