Production
1. Suitable for molding large and super large parts
In most plastic molding processes, during the molding process, the plastic and the mold are under very high pressure (pressure), such as injection molding, compression molding, and extrusion, which are widely used. Therefore, when applying these molding processes to produce large plastic parts, not only must the mold that can withstand great pressure be used, which makes the mold bulky and complicated, but also the plastic molding equipment must be designed and manufactured very firmly. The difficulty in processing and manufacturing of the product is correspondingly increased, and the cost is increased. In contrast, because the rotomolding process of anticorrosive storage tanks only requires the strength of the frame to support the weight of the material, the mold and the frame itself, as well as the closing force to prevent material leakage, even if the rotomolding of large and super large plastic parts , Anti-corrosion storage tanks do not need to use very heavy equipment and molds, the processing and manufacturing of the machine molds is very convenient, the manufacturing cycle is short, and the cost is low. 1. Theoretically speaking, there is almost no upper limit on the size of the parts formed by the rotational molding process. But it is easily restricted by production conditions and road transportation. However, it is impossible to produce such a large plastic container using spit molding without very expensive and huge blow molding equipment.
2. Anti-corrosion storage tanks are suitable for many varieties
Production of small batches of plastic products. Because the mold for rotational molding is not affected by external force, the mold is simple, inexpensive, and convenient to manufacture. In addition, the rotomolding equipment also has greater mobility. A rotomolding machine can not only install a large mold, but also arrange multiple small chess sets; it can not only mold parts of different sizes, but also simultaneously Products with very different molding sizes and shapes can be rotomolded at the same time as long as the rotomolded products use the same raw materials and the same thickness. Therefore, the rotomolding process of anticorrosive storage tanks has greater flexibility than other molding methods. . 3. Rotational molding is very easy to change the color of the product. Rotational molding adds materials directly to the mold each time, so that all materials enter the product. After the product is removed from the mold, the materials needed for the next molding will be added. Therefore, when we need to change the color of the product, we will not waste a bit. The raw materials do not need to spend time cleaning up the machine and mold anticorrosive storage tanks. When we use multiple molds to rotomold the same plastic product, we can also add materials of different colors to different molds, and rotomold plastic products of different colors at the same time.
