Injection molding cycle time by a mold, filling time, dwell time, cooling time and the release time components. Among them, the largest proportion of the cooling time, about 70% to 80%. Accordingly, the cooling time will directly affect the plastic molding cycle length and the volume of production. Stage plastics release temperature should be cooled to below the heat distortion temperature of the plastic products, to prevent warping due to the slack of plastic products due to residual stress or external forces caused by the release and deformation. Injection mold (Rotational Mold) rotational molding process is to first join plastic mold and die along two perpendicular axes of rotation allowed to continue heating, plastic mold under the action of gravity and heat of good quality plastic processing plant, gradually uniformly coated, melt adhesion over the entire surface of the cavity formed into the desired shape 350 tons of plastic plants, stereotypes and to the cooling system. Second, the rotational molding process compared to conventional blow molding, injection molding process has the following advantages: 1, the cost advantages: rotational molding process requires only enough to support the strength of the frame materials, mold and frame its own weight, to prevent mold closing force leaked material; and material throughout the molding process, in addition to the role of natural gravity, almost without any external force plastic factory, which is fully equipped with a convenient machine mold manufacturing and plastic processing plants Bao'an short period low-cost advantage. 2, the quality advantage. Rotomolding products throughout the production process, because no internal stress, product quality and more stable structure. 3, flexible advantage. Rotomolding machine mold manufacturing convenience, low prices, it is especially suitable for development of new products in many varieties, small batch production. 4, personalized design advantages. Rotational molding process of the product easy to change color, and can be done hollow (seamless, welded), the surface treatment can be done on the effect of the pattern, wood, stone and metal, meet the modern social consumer goods The individual needs.
