The main features of the rolling process are as follows:
1, Rolling mold cost low - the size of the same size of the product, the cost of rolling mold is about blow molding, injection mold cost of 1/3 to 1/4, suitable for forming large plastic products;
2, rotational molding product edge strength is good - rotational molding can realize the product edge thickness more than 5 millimeters, thoroughly solve the hollow product edge thinner problem;
3. Rotational molding can be settled the inserts.
4, The shape of rotational molding products can be very complex, and the thickness can be more than 5 millimeters.
5. All closed products can be produced by rolling plastic.
6. Rotational molding products can be filled with foam materials to achieve insulation.
7, Without adjusting the mold, the wall thickness of rotational molding products can be adjusted freely (above 2mm).
