In terms of forming

1) products of uniform wall thickness, and no scraps, no weld molding wall thickness range of products, such as polyethylene rotational molding, wall thickness range within the 1~16mm. But because of the relationship between viscosity and thick-walled molding is difficult. Rotational molding process is particularly suitable for molding 2~5mm plastic products.

2) typically hollow or shell products manufactured, solid product processing difficulties. And surface condition on mold cavity surface stresses.

3) rotation molding products size accuracy, accuracy typically ± 5%.
