1, rotational mold cost is low: the same specification and size of products, the cost is about rotational molding blow molds, injection mold cost 1 / 3 to 1 / 4; 
 2, the rotational products edge strength, and rotational molding products can achieve the thickness of the edge of more than 5 mm, completely solve the problem of hollow thin edge products; 
 3, to accommodate a variety of mosaic pieces rotational; 
 4, the shape of rotational molding products can be very complex, and the thickness of more than 5 mm; 
 5, rotational molding can produce closed products; 
 6, rotational molding products can be filled with foam material, to achieve thermal insulation; 
 7, no need to adjust the mold, rotational molding products can be free to adjust the thickness (2mm above); 
 8, rotational molding hollow seamless product, but you can adjust the thickness, so that products with high strength; 
 9, the rotational pattern can provide a variety of surface treatment, production of color products, can be used for UV protection anti-aging treatment for a variety of stone, wood simulation results. 
 Relative to the injection: Rotational products can be achieved, hollow and seamless, higher intensity (achieved by adjusting the thickness), products of relatively low cost of large size, the surface shape can be more complicated. Relative to the blow: rotational molding products, products, high strength, solid corners, inserts and good selectivity
