Discussion on the Continuously Expanding Application Fields of Rotational Plastic Processing Products
Rotational molding is a branch of plastic processing technology, which has advantages such as less equipment investment, low mold cost, flexible and diverse product design forms, and integrated molding compared to other plastic processing processes. In recent years, in developed countries in North America and Europe, the rotational molding industry has developed rapidly, with a development speed higher than the average development speed of the entire plastic industry. The development of the entire rotational molding industry is also relatively complete. In addition to rotational molding machine manufacturing factories and rotational molding product production factories, there are also a considerable number of other professional auxiliary factories, such as rotational molding mold manufacturing factories, release agent production factories, rotational molding specialized pigment production factories, milling machine manufacturing factories, embedded parts manufacturing factories, and mixing equipment manufacturing factories suitable for rotational molding, as well as numerous rotational molding specialized raw material supply factories, and so on. The rotational molding equipment manufactured in developed countries is also becoming increasingly sophisticated, constantly developing towards higher levels of automation control.

An important factor driving the development of the rotational molding industry is the automation and high-performance of rotational molding equipment, improving processing efficiency, reducing production costs, shortening rotational molding time, increasing output, and further improving product design freedom. Industry insiders believe that to achieve this goal, one is to develop new polymers, additives, and colorants that can directly enter the automatic feeding system of the rotational molding mold at any location, making it possible to form multi-layer rotational molding components and high-performance fiber reinforced plastic, and automatically control the cooling inside the mold; The second is to shorten the processing cycle through automatic feeding, heating, cooling, demolding and other processes, reduce the internal stress of polymers, improve the dimensional stability of products, and open the door to the application of high value-added engineering plastic rotational molding.
At present, improving the level of automation in production has become the goal pursued by rotational molding processors, driving the development of rotational molding production equipment towards automation. This production line can independently complete operations such as feeding, mold opening, and product removal. The products that can be produced include water tanks, fire extinguisher boxes, rowing boats, toys, roofs, and pallets. The Italian plastic and rubber industry has decades of rich experience in rotational molding technology. The shuttle type of rotational molding is characterized by its flexibility and efficiency improvement. Fully automatic electric heating rolling forming technology to meet the high-performance rolling processing of different materials.
The application scope of rotational molding products is constantly expanding, involving industries such as agricultural machinery, transportation vehicles, traffic safety measures, entertainment industry, river and waterway dredging, construction industry, water treatment, medical food, electronics, chemical industry, aquaculture, textile printing and dyeing, etc.
