At present, the industries involved in rotational molding products at home and abroad include transportation tools, traffic safety facilities, entertainment industry, river channel dredging, construction industry, water treatment, medical food, electronics, chemical industry, aquaculture, textile printing and dyeing, etc.  However, rotational molding is the most economical and effective method to produce large hollow plastic products. To promote the application of rotational molding in China, it is necessary to absorb foreign advanced technologies, develop more and better rotational molding materials, improve the automation level of rotational molding equipment, and shorten the mold design and manufacturing cycle.

In order to adapt to the new situation of increasing varieties of rotational plastic products, increasing scientific and technological content of rotational plastic products, and increasing demand for rotational plastic products from all walks of life, China Plastics Processing Industry Association has established a rotational plastic professional committee.  The purpose is to exchange rotational molding production technology and experience, digest and absorb foreign advanced technology and equipment, strengthen technical cooperation, promote the development of China's rotational molding technology, processing equipment and mold, and develop rotational molding special materials and products.　

Containers are rotational molded parts, which are widely used in storage and feeding boxes, water storage tanks, storage and transportation containers for various industrial chemicals, such as acid, alkali, salt, chemical fertilizers, pesticide storage tanks, washing tanks, reaction tanks, turnover boxes, garbage cans, septic tanks, domestic water tanks, etc. in chemical enterprises, industrial coating, rare earth production, etc.

Rotational molding parts for vehicles mainly use polyethylene and polyvinyl chloride paste resin to rotationally mold various automobile parts, such as air conditioning bent pipes, vortex tubes, backrest, handrails, oil tanks, fenders, door frames and gear lever 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.  Rotational molding technology injects endless imagination of designers into products.  Designers can choose the best materials in the manufacturing process, including various materials approved by the Food and Drug Administration.

Additives put into the production process can effectively resist the invasion of climate, electrostatic interference and other external objective factors.  In the design process, the insertion opening, screw thread, handle, inverted device and perfect surface design are all one of the highlights.  Designers can also design multi-wall molds, the interior of which can be either hollow or filled with foam.

Boxes made by rotational molding process are all in accordance with the standard of military boxes in terms of thickness and strength, so the military also chooses boxes made by rotational molding process as the material boxes for purchase.  The thickness of the box wall made of rotational molding is uniform, the thickness at the corner is the thickest, and the structural strength is reasonable to prevent falling and smashing.  Shanghai Canggu Plastic Technology Co., Ltd. specializes in making military rotoplastic boxes.

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