What is Rotational Molding?

Rotational moud or Roto Molding which is a high temperature, low volume, low pressure thermoplastic forming process .It mainly suite for producing hollow, one piece parts such as large oil or chemical tanks, kayaks, point of purchase displays, frames, cases, furniture,

carts, dispensers, park equipment. The material can be UV resistant which can ensure the outdoor use of your products .

The principle of rotational molding of plastics is simple. Basically the process consists of introducing a known amount of plastic in powder, granular, or viscous liquid form into a hollow, shell-like mold.The mold is rotated and/ or rocked about two principal axes at relatively low speeds as it is heated so that the plastic enclosed in the mold adheres to, and forms a monolithic layer against, the mold surface. The mold rotation continues during the cooling phase so that the plastic retains its desired shape as it solidifies. When the plastic is sufficiently rigid, the cooling and mold rotation is stopped to allow the removal of the plastic product from the mold. At this stage, the cyclic process may be repeated. The basic steps of (a) mold charging, (b) mold heating, (c) mold cooling, and (d) part ejection are shown in Figure below.
