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. It can be even larger if we do not consider the limit of transportation condition. Rotational molding products can be divided into three size, cylinder water tank （0.25M3~ 50 M3）, open circular bucket（20L~3000L）and open square bucket（30L~2000L）These products can also be made into different kinds of closed containers according to functional requirements of different industries.
