Roto Moulding Process

Roto Moulding

Roto-Moulding, A recent technology in plastic process, which has received wide acceptance the world over. With advantages certain to attract both manufacturers and users, roto-moulding has useful applications in conventional and imaginative products lines. The option to create one piece, seamless and stress free plastic products with superior surface finish is here. Products can be gigantic or small, in every conceivable shapes and of utilitarian and even exotic nature. Roto-moulding offers a definite production and cost advantage over other processes.

A simple and unique process

The process is simple in concept:

  1. Heat is used to melt and fuse plastic resin in moulds which rotate in two axes.
  2. No pressure used unlike other processes.

Actual process in three stages:

  1. Resin loaded in the mould, fitted on arm head.
  2. Mould moves into heating chamber. where resin melts under high temperature and fuses into inner surface of the moulds.
  3. Moulds transferred to cooling stations, where it is cooled gradually by a combination of cool air and water spray

Finally, the finished product is unloaded and fresh material charged.

Unmatched Advantages

  • Roto-moulding commits itself to economy, design and production advantages.
  • Low capital investment in machine and moulds.
  • Since no pressure used, tooling cost low and moulds can be light weight.
  • Inexpensive modifications of moulds at prototype stage possible.
  • One piece seamless products with negligible scrape are produced.
 
  • Uniform wall thickness and smooth surface finishes are achieved.
  • Double wall product configuration can be made.
  • Complex outline with excellent surface definition is possible.
  • Metals inserts / handles can be moulded into the product.
  • Identical or similar items, different sections or one part in different colours can be moulded in a single arm simultaneously.
