1. Cost advantage: in the rotational molding process, only the strength of the frame is required to support the weight of materials, molds and the frame itself, so as to prevent the mold closing force of material leakage; In addition, the material is hardly affected by any external force except the natural gravity in the whole molding process, so it has the advantages of convenient machining and manufacturing, short cycle and low cost.
2. Quality advantage. In the whole manufacturing process, the products with rotational molding process have more stable quality and structure due to no internal stress.
3. Flexible advantages. The machine mold of rotational molding process is easy to manufacture and cheap, so it is especially suitable for the production of multiple varieties and small batches in the development of new products.
4. Personalized design advantages. The products in the rotational molding process are easy to change colors, and can be hollow (seamless without welding). The effects of patterns, wood, stone and metal can be achieved in the surface treatment of products, so as to meet the personalized needs of consumers in modern society.
