Rotational molding (roto moulding) involves loading plastic resin into a mold, rotating the mold slowly, heating the mold externally, thereby melting the resin powder and uniformly coating the surface of the entire cavity of the mold by its own gravity, and finally obtaining a hollow product after cooling.
Features of the rotomolding process:
1. Low cost for mold tooling: For the same product size, rotomolding mold is about 1/3 to 1/4 of the cost of blow mold and injection mold. However, this rule doesn't apply to product unit cost.
2. Rotomolding products have good edge strength, comparing to blow molding for the same hollow product. Edge thickness can be of more than 5 mm.
3. You can manufacture products with very complicate shapes (too costly or impossible to make by injection molding).
4. Easy to place metal inserts such as bolt and fittings.
5. Rotomolding can produce fully closed products.
6. Roto molded products can be filled with foaming materials to achieve heat insulation.
7. The wall thickness of the rotomolded product can be adjusted freely (more than 2mm), without the need to remake mold. Greater wall thickness means stronger (but heavier) product.
8. A variety of surface color and pattern is possible. We typically do anti-UV anti-aging treatment and matte finish.
