At present, the industries involved in rotomolding products at home and abroad include transportation, traffic safety facilities, entertainment industry, dredging of rivers and rivers, construction industry, water treatment, medicine and food, electronics, chemicals, aquaculture, textile printing and dyeing, etc. Rotational molding is the most economical and effective way to produce large hollow plastic products. To promote the application of rotational molding in China, it is necessary to absorb advanced foreign technology, develop more and better rotomolding materials, and improve the automation level of rotomolding equipment. Shorten the mold design and manufacturing cycle.

In order to adapt to the increasing variety of rotomolding products, the increasing scientific and technological content of rotomolded products, and the increasing demand for rotomolding products in various industries, China Plastics Processing Industry Association has established a rotomolding professional committee. It aims to exchange the production technology and experience of rotomolding process, digest and absorb foreign advanced technology and equipment, strengthen technical cooperation, promote the development of China's rotational molding process technology, processing equipment and molds, and develop rotomolding special materials and products.

Container-type rotomolded parts, such plastic parts are widely used in storage and supply tanks, water storage tanks, various industrial chemical storage and transportation containers, such as acid, alkali, salt, chemical fertilizer, pesticide storage tank, chemical Washing tanks, reaction tanks, turnover boxes, garbage bins, septic tanks, domestic water tanks, etc. in enterprises, industrial coatings, rare earths.

Rotomolding parts for vehicles, mainly using polyethylene and polyvinyl chloride paste resin, rotomolding various automotive parts, such as air conditioning elbows, vortex tubes, backrests, handrails, fuel tanks, fenders, door frames and shift levers Covers, battery housings, fuel tanks for snowmobiles and motorcycles, aircraft fuel tanks, yachts and their water tanks, boats, and shock absorbers between boats and docks. The rotomolding process injects the endless imagination of the designers into the product. Designers can choose the best materials for the production process, including the various materials approved by the Food and Drug Administration.

The additives placed in the production process can effectively resist external factors such as climate invasion and static electricity interference. In the design process, the insertion port, the thread, the handle, the inverted device, and the perfect surface design are among the highlights. Designers can also design multi-wall molds that can be either hollow or filled with foam.

It is believed that with the continuous advancement of modern materials industry and machinery manufacturing and automation technology, the rotational molding process will have rapid development in China.
