Rotational molding process, usually by charging, heating rotational molding, cooling, mold release, mold cleaning a few basic steps is composed of some, but in many cases, often also need a product after processing (sorting) process, to get practical for plastic products. (1) filling the first resin and various additives required to join through accurate measurement (sometimes still need to first of each component premixed uniform) Qingyun large plastic barrels, adding to the rotational mold, and then lock the mold to ensure that the mold during the rotation, the material therein will not leak out from the clamping point. (2) heating, good rotomolding mold material loaded into the heating furnace (or to the jacket of a jacketed rotational mold through the heat medium), the mold is rotated while constantly while heating. As the mold is along two mutually perpendicular axes of rotation, under the action of gravity, slide down toward the opposite direction of rotation of the mold the material in the mold, to each point of contact with the wall of the mold cavity, and because the mold wall Incoming plastics and gradually heat the plastic adheres to the entire inner surface of the mold to form plastic parts we need. (3) material is cooled within the mold, the mold is rotated, heating and uniformly attached to the mold surface and later fully plasticized by cooling molded plastic to have its shape fixed. In most cases, during cooling is necessary to prevent the downward flow of the material (lower mobility), in the cooling unit should continue to drive the rotomolding mold along two perpendicular axial rotation, until the "cold through" (material loss of mobility) so far. (4) releasing the machine is stopped, the mold is opened, remove the plastic parts. Under normal circumstances, take more artificial release; mass production (especially a rotomoulded article only when multiple), also mechanical demolding. (5) After removing the mold parts to clean, clear in the mold cavity and the mold at the residual burrs and other debris, to prepare for the next cycle rotomolding purposes. After a number of cycles to form a rotational too, often also need to remove the damaged good mold release and re-coated with the new release agent. 5, except among the above, the application of more rotational molding products and various cabinet, housing, large pipes and other parts, such as crates, bins, machine shell, protective cover, shade, bathroom, toilet and telephone yachts and so on. Rotomolding products have a broad impact on the use of liquid chemical storage and transportation, chemical industry, industrial coating, rare earth in preparation wash tank, reaction tank, etc., as well as Hohai buoys, water tanks and other areas of life. Features plastic PE rotomolding tank are: 1, rotomolding products edge strength, rotational molding products can be achieved thickness of the edge more than 5 mm, completely solve the problem of hollow thin edge products. 2, rotational various inserts can be placed; 3, the shape of rotational molding products can be very complex, and the thickness of more than 5 mm; 4, rotomolding products can produce completely closed; 5, rotomolding products can be filled with foam, realization of insulation. 6, no need to adjust the mold wall thickness rotomolding products can be freely adjusted (2mm above). 7, the product of hollow seamless large plastic bucket, but you can adjust the thickness, so that products with high strength. 8, can provide a variety of surface pattern processing, production of various color products, can be used for anti-aging treatment UV Texas large plastic barrels, for a variety of stone, wood simulation results. Reminder, PE plastic water tank installation instructions and precautions: 1. Each tank drove into the water, the water two holes, there are special requirements for separately. 2. The tank should be placed on the roof of the force of the stair good bay or platform. 3. tank container for the Cape, it should be installed to control the liquid level float or other effective control device. 4. After assembling Hebei plastic barrels, close the outlet pipe and vent pipes, open into the water, turn on the water side to side to check filled with water, 12 hours watertight qualified. 5. The tank should be cleaned regularly to prevent debris into the box 6 to test the water, the general conditions for the tank temperature, pressure 7, rotational tank corrosion on large-sized large-capacity bulk products in a very large advantage, despite the large volume, but only once and then maintain the integrity of forming characteristics, which is less than the storage tanks at the other processes are up.
