Process of plastic tank has many kinds, there are a variety of molding process of plastic and composite materials, in addition to our common extrusion molding, injection molding, blow molding process, a processing method of rotational molding plastic products is also. At present, the development of foreign rotomolding industry quickly, while domestic due to various factors, such as the processing cycle is slower and material constraints with the rotational speed of industrial development, lower than other plastics processing industry.
Rotational molding is a considerable market general manufacturing process. It will provide the design unlimited space for you, and only very low manufacturing cost of the product you have to pay. The production process before the rotational molding production process, you need to prepare some good quality of the mold, and placing it in a shaping machine, this machine are respectively provided with casting heating and refrigeration of the two device. In the set, first put a few pieces of the mold on the machine above. Then, in early rule type plastic resin in each mold, and then the die from the two angles of vertical and horizontal circling slowly put into the oven. The resin melt will die and the outer packing hot evenly and tightly bonded together. Then, and then mold into the refrigeration cycle device, make the mold in which continues to rotate until its every part thickness are consistent. When the mold is frozen after the end, from the machine to take down. In the whole production process, the mold rotation speed, heating and cooling time all must pass through the precise control of strict. Compared with other design advantages of die technology, rotational molding process provides more design space for us. Under the right design, we can put a few parts are combined into a complete mold, this approach greatly reduces the assembly cost is high. Rotational molding production program also includes a series of inherent design way of thinking, such as how to reconcile the side wall thickness, how to strengthen the external settings. If you need to add some affiliated design it, then we can also strengthen rib line this link is added to the design. Plastic tank of rotational molding injection of endless imagination for product designers. Designers can select material for making the best during the production process, including a variety of materials, the food and Drug Administration approved. The production process into the additive can effectively resist climate invasion, electrostatic interference and external objective factors. In the design process, the insertion opening, screw, handle, collapsing device, design of surface perfect is one of the hotspot which. Designers also can be designed into multi wall type mold, its interior can be hollow, and can be filled with foam. Cost advantage when cost also become a factor in our consideration, rotational molding process has more advantages than other types of market process. And blow molding and injection molding process in contrast, rotational molding process can be an easy job to produce more parts of different sizes in a cost effective range. His die also relatively low to many, because it does not need to complete the production of some inner core. But in the absence of the internal core of the circumstances, as long as a little change can be made into another model. Because each component production process are in high temperature and spinning process flow finished, different from those formed in under the weight of the components of rotational moulding, so don't need to be like injection molding process that also requires special processing can withstand the stress tests. As for the production of conversion products production cost is also decreased, because light plastic to convert heavy plastic, requires more raw materials. For the rotational molding process, saving the cost of the original single type consumption mode is towards the future development of high yield. Therefore one of the application of plastic tank is rotational.
