The efficiency of plastic-crowding machines is largely reflected in high output, low energy consumption and low manufacturing costs. In terms of functionality, the screwdriver, which has been used not only for crowding out and refining high-molecular materials, has expanded its use to such areas as food, feed, electrodes, explosives, building materials, packaging, pulp and ceramics。
The large size of the plastic extruder can reduce production costs, which is more evident in large double-snail plastic granulation units, membranes, pipe crowding out units, etc. The major technical equipment required for the state-focused construction services and the long-term dependence on imports of the large crowding particle fleet of one of the three key equipments associated with the large ethylene project had to accelerate the process of domesticization to meet the needs of petrochemical industrial development。
