Plastic Balls Manufacturer introduces the main advantages of rotomolding:

1. Suitable for molding large and extra large parts.
The vast majority of plastic molding processing technology, during the molding process, the plastic and mold are under a relatively high pressure (pressure), such as extremely widely used injection molding, compression molding, extrusion. Plastic injection, etc. Therefore, when using these molding processes to produce large plastic parts, not only must you use molds that can withstand a lot of pressure, which makes the molds cumbersome and complicated, but also the plastic molding equipment must be designed and manufactured very firmly. The difficulty of processing and manufacturing increases accordingly, and the cost increases. On the contrary, because the rotomolding process only requires the strength of the frame to support the weight of the material, mold and frame itself, and the closing force to prevent the leakage of the material, even if the rotomolding large and extra large plastic parts, there is no need Using very bulky equipment and molds, machine mold manufacturing is very convenient, with short manufacturing cycle and low cost. In theory, there is almost no upper limit on the size of the parts formed by the rotational molding process. It is impossible to produce such a large plastic container without the use of very expensive and bulky blow molding equipment.

2. It is suitable for the production of multiple varieties and small batches of plastic products.
Since the mold for rotomolding is not affected by external forces, the mold is simple, inexpensive, and easy to manufacture. In addition, the rotomolding equipment also has greater mobility. A rotomolding machine can install a large mold or arrange multiple small chess sets; it can not only mold parts of different sizes, but also at the same time. Products with very different sizes and shapes can be rotomolded at the same time as long as the raw materials used in the rotomolded products are the same and the thickness of the products is the same. Therefore, the rotomolding process has more flexibility than other molding methods.

3. Rotational molding is easy to change the color of products.
Rotational molding adds materials directly to the mold each time, which makes all the materials enter the product and is removed from the mold before adding the materials needed for the next molding. Therefore, when we need to change the color of the product, we will not waste bits and pieces. The raw material does not need to spend time to clean the machine and mold. When we use multiple molds to rotationally mold the same plastic product, we can also add materials of different colors to different molds, and at the same time rotomold plastic products of different colors.

4. Suitable for forming hollow parts of various complex shapes.
In the rotomolding process, the materials are gradually coated and deposited on the inner surface of the mold. The products have a strong replication ability for the fine structures such as the patterns on the mold cavity; at the same time, because the mold is not affected by the outside during the molding process Pressure, you can directly use precision casting and other methods to produce a mold with a fine structure and a complex shape.

5. Save raw materials.
The wall thickness of the rotomolded products is relatively uniform and the chamfers are slightly thicker, so it can give full play to the effectiveness of the materials and is conducive to saving raw materials. In addition, in the rotomolding process, there are no waste materials such as runners and gates. In the production process, almost no charge is returned, so the utilization rate of the process for the material is extremely high.
