Plastic machinery is a general term for all kinds of machinery and devices used in the plastics processing industry. At present, plastic machinery has obvious qualitative changes: the process is more complicated and highly automated technical equipment. Therefore, the requirements for the mathematical model of the process and its consistency with the actual conditions of the polymer processing are improved. In the process of producing the film, the structure of the traditional machine used to prepare the melt, such as the screw extruder, has a fundamental change, using a new type of filter, head and film heat treatment and traction device, etc. structure. Improvements in the process and equipment for producing the film can increase the productivity of the line by 0.5-1.0 times, and the film thickness difference is reduced by 50%.
In the current machine manufacturing, the principle of combination is widely used in the construction of equipment, that is, each major mechanism in the process can independently perform the maximum possible function. This can be used not only to improve the uniformity of the equipment, but also to modernize the production line in a timely manner and to create favorable conditions for replacing outdated devices and institutions. For example, the use of a multi-segment screw with shearing and mixing elements, as well as a grooved barrel inside, can increase the productivity of the extruder by a factor of 0.5 to 1 and maintain the necessary melt temperature and uniformity.
Therefore, with the continuous development of the social economy, plastic machinery is also undergoing such a huge change. I believe that this change will bring more and more benefits to everyone.
