1, suitable for large-scale and large molded parts. Most plastic molding process, in the molding process, plastic and molds are at very high pressure (pressure) under the extremely wide range of applications such as injection molding, compression molding, extrusion. Spit plastic, etc., so large-scale application of these molding process to produce plastic parts, not only must be able to withstand the enormous pressure of the mold, the mold becomes bulky and complex, and plastic molding equipment must be designed, manufactured have been very strong, machine model The corresponding increase of manufacturing difficulty and cost increases. On the contrary, since the rotational molding process requires only enough to support the material strength of the rack, the rack itself and the weight of the mold, and to prevent leakage of the material clamping force, even of large and extra large rotational molding plastic parts, and without the use of very heavy equipment and molds, mold manufacturing machine is very convenient, short manufacturing cycle, and low cost. Theoretically, a rotational molding process of molding parts, the size is almost no upper limit. The production of such large plastic containers, such as plastic molding using the spit, not very expensive and large blow molding equipment is not possible. 2, for more variety, small batch production of plastic products. Since rotational molding die without external force, so the mold is simple, inexpensive, easy to manufacture. In addition, the device also has a large rotational mobility, a rotational molding machine, either install a large mold, you may arrange more than just a small chess; it can not only molded parts of different sizes, but also can simultaneously molding size and shape are very different products, as long as the raw materials used in the same rotational molding products, product thickness considerably, may also rotational molding, rotational molding process so than other molding methods have greater mobility. Material: imported food grade polyethylene (PE) product models are: 0.5 tons, 0.5 tons, 1 ton, .1.5 tons, 2 tons, 3 tons, 4 tons, 5 tons, 6 tons, 8 tons, 10 tons , 12 tons, 15 tons, 20 tons, 25 tons, 30 tons, 35 tons, 40 tons, 45 tons, 50 tons.
