75L Cooler Plastic Case Molding Aluminum A356 6061 T6 Material Smooth Surface

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.

Product Parameter 

Product Advantages

1. Mould and rotational molding machines are relatively low, and the service life is long

2. Rotational molding process can be made from small children's toys to common automobile plastic parts until the huge engineering plastic products, especially the super large and non-standard special-shaped hollow plastic products, and the large product is difficulty in processing of extrusion, injection and blow molding process

3. Low cost, has more advantages than the rotational molding technology of other types of market

4. Rotational molding technology can be applied to a wide range of industries, such as industry, agriculture, military, aviation, shipping, automobile fittings, transportation, engineering machinery, leisure and entertainment, furniture, food, health care, security, environmental protection and other many fields
