Suitable for molding large and extra large parts. The company is located in:Most plastic molding process, in the molding process, plastic and mold are under very high pressure (pressure), such as the application of a very wide range of injection molding, compression molding, extrusion. Blow molding, etc. Therefore, when using these molding processes to produce large-scale plastic parts, not only the molds that can withstand a great pressure must be used, the molds become thick and complicated, but also the plastic molding equipment must be designed and manufactured with very strong molds The corresponding increase in the difficulty of processing and manufacturing, the cost increase. On the contrary, since the rotational molding process only requires that the strength of the frame be sufficient to support the weight of the material, the mold and the frame itself and the mold clamping force to prevent material leakage, it is not necessary to rotationally mold large and extra large plastic parts The use of very crude equipment and mold, machine mold manufacturing is very convenient, short manufacturing cycle, low cost. In theory, parts molded with the rotomolding process have almost no size limit. The production of such large plastic containers, such as the use of blow molding, not very expensive and huge blow molding equipment is impossible. The company is located in:For multi-species, small quantities of plastic products. The company is located in:As the rotational molding mold with no external force, so the mold is simple, cheap, easy to manufacture. In addition, the rotational molding equipment also has greater flexibility, a rotomolding machine, either a large mold can be installed, but also can arrange multiple small pieces of chess; it can not only mold parts of different sizes, but also at the same time Molding products are very different size and shape of the products, as long as the raw materials used in the same rotational molding products, products, the thickness of the same, both rotational molding, so the rotational molding process than other molding methods have greater flexibility. The company is located in:Rotational molding easy to change the color of products. The company is located in:Rotational molding Each time the material is added directly to the mold, which makes the material all into the product After the product is removed from the mold, and then add the material needed for the next molding, so when we need to change the color of the product, both Do not waste bit by bit raw materials, do not need to spend time cleaning machinery and mold. When we use multiple mold rotomolding to mold the same kind of plastic products, it is also possible to add different color materials into different molds and to roll plastic products of different colors at the same time. The company is located in:Suitable for forming a variety of complex shapes of hollow parts. The company is located in:In the process of rotational molding, the material is gradually coated and deposited onto the inner surface of the mold, and the product has a strong ability to copy the fine structure such as the pattern on the mold cavity. At the same time, since the mold is not affected by external Pressure, you can directly use precision casting and other methods with fine structure, complex shape of the mold. The company is located in:Save raw materials The company is located in:Rotational plastic products, the wall thickness is relatively uniform and slightly thicker chamfer, it can give full play to the effectiveness of the material is conducive to saving raw materials; In addition, the rotomolding process, there is no runner, gate and other waste, once commissioned after , Almost no back to the production process, so the process for the utilization of materials is extremely high.
