SPECIFICRotational molding products have developed from normal civilian products to industrial products. The focus of the function has transferred from containing to structural adjustment. With the development of rotational molding equipment,Website:http://www.wanma-roto.com, the complexity of rotational molding products structure has developed beyond our imagination. Rotational molding can make products which injection molding, blow molding and extrusion molding can’t do. Moreover, the geometry size of rotational molding can reach from 0.5L to 50M3. The raw material LLDPE can resist acid and alkali, the product tough and durable, safe and cost lower than metal
