Rotational Molding Process Overview:
In Rotational molding, liquid or powdered thermoplastic resin is formed inside aclosed mold or cavity while the mold is rotating biaxially in a heating chamber.To obtain mold rotation in two planes perpendicular to each other (providing even distribution of the resin), the spindle is turned on a primary axis, while molds are rotated on a secondary axis.
Rotational Molding (also popularly known as Rotomolding) is best suited for large, hollow products requiring seamless construction (for strength), complicated curves, a good finish, a variety of colors, and uniform wall thickness.
The process has been used for products such as water tanks, storage tanks, industrial containers, outdoor chairs and benches, road barriers, portable outhouses,modular bathrooms, garbage cans, telephone booths, boat hulls, light globes , ice buckets, appliance hoousings (carpet and vacuum cleaners), and toys. The technique is applicable to most thermoplastics but is most widely used with polyethylene.
