Advantages of rotational molding processing technology in production and processing

Suitable for large, medium and giant rubber products
The vast majority of plastic forming processes involve the plastic and molds being subjected to extremely high working pressure (gas pressure) throughout the entire forming process, such as the widespread use of injection molding, shrinking rubber products, and extrusion When using this forming processing technology to produce large and medium-sized Plastic Parts, such as injection molding, it is necessary to not only use molds that can bear very high work pressure, making the molds increasingly heavy and complex, but also design and manufacture plastic forming machinery and equipment that are very sturdy. The difficulty factor of production, processing, and manufacturing of the molds is relatively increased, and the cost increases.

On the contrary, because the rotational Molding Process only specifies that the compressive strength of the sound card frame is sufficient to support the net weight of the raw materials, molds, and sound card frame itself, as well as the closing force to avoid material leakage, even for large, medium, and giant plastic parts that are rotational molded, there is no need to use very heavy machinery and molds. The production, processing, and manufacturing of machine molds are very convenient, with a short production cycle time and low cost.

In theory, there are basically no restrictions on the specifications of parts formed by rotational molding processing technology. It is unlikely to produce such large Plastic Containers without expensive and huge injection molding machines and equipment, if injection molding is used.

Suitable for the production and manufacturing of various types and small batches of plastic products

Because the molds used for rotational molding are not subjected to external forces, the molds are simple, of high quality and low cost, and easy to manufacture. In addition, the rotational molding machine equipment also has great maneuverability. One rotational molding machine can install one large and medium-sized mold, as well as allocate multiple small and medium-sized chess sets; It can not only produce parts with different sizes of rubber and plastic products, but also shape products with extremely different sizes and appearances. If the raw materials used for the rotational molding mold are the same and the product thickness is very thin, it can be molded separately. Therefore, the rotational molding processing technology has higher controll ability compared to other forming methods.

Rotomolding is very easy to change the color tone of the product
rotomolding immediately adds raw materials to the mold each time, which ensures that all raw materials are fed into the product. After the product is removed from the mold, the necessary raw materials for the next molding are added. Therefore, when we need to change the color tone of the product, we do not have to consume bits and pieces of raw materials, nor do we have to spend time clearing equipment and molds. When we apply multiple molds to roll mold the same plastic product, we can also add raw materials of different colors to different molds and roll mold plastic products of different colors.

Suitable for forming various complex hollow parts
During the entire process of rotational molding, raw materials are slowly applied and accumulated on the inner surface of the rotational molding mold. The product has strong copying ability for fine structures such as patterns on the mold concave mold; In addition, because the mold is not subjected to external working pressure during the entire forming process, it is possible to immediately use precision casting and other methods to produce molds with fine structures and complex appearances.

Economize raw materials
The thickness of the rotational molding product is relatively uniform and slightly thicker at the rounded corners, so it can fully utilize the efficiency of raw materials and is beneficial for saving raw materials; In addition, during the entire process of rotational molding, there are no waste materials such as flow channels or inlet ports. Once adjusted, there is basically no waste material returned to the furnace during the processing, so this processing technology has a very high utilization rate for raw materials.
