The screw feeder is blended and plasticized into extrusion screw pure plasticizing extrusion. During the whole plasticizing process, the screw length-diameter ratio of material plasticizing experience is unchanged and the plasticizing quality is consistent. The plasticization formed by the change of screw length-diameter ratio of material plasticizing experience of conventional screw reciprocating plasticizing injection is overcome by using central feeding system. The defect of uneven quality ensures the consistency of specific volume of materials in melting state and greatly improves the quality of plasticization.
The automatic feeding system can also ensure the consistency of the materials in the injection moulding machine to avoid material moisture regain. Under the action of vacuum negative pressure, some dust of the materials in Cathaysia can be filtered out through the filter (dust collector) system, which is beneficial to improving product quality. Characteristic individualization: The central material supply system can achieve different users, different workshop characteristics, different material application requirements. They can design the best plan according to the need of practice. Establish a modern factory image together: the central feeding system will reduce the pollution of materials and dust to the lowest level, so as to adhere to a clean production workshop, while the central feeding system has a unique centralized dust recovery system, which is faster and more environmentally friendly, reaching the 100,000 class dust-free room operation requirements. In the end, the unmanned automated production workshop can be completed and the image of modern factory management can be established by reducing noise. The control console of central feeding system is simple and clear. The EV color panel is easy to operate. It can show the operation of suction barrel. The PLC can be programmed. It is superior to the traditional one. The circuit can control multiple suction points. By using the central feeding system, the defects of uneven plasticizing quality caused by the change of the length-diameter ratio of the screw used in the conventional screw reciprocating plasticizing injection are overcome, and the consistency of the specific volume of the material in the melting state is ensured, and the plasticizing quality is greatly improved.
