What preprocessing should be carried out in Dalian injection molding

Release date:2018-07-19 00:00 Source:http://www.mjaupanda.com Views:

Injection molding is a method to get the molded product by mixing the completely molten plastic material through a screw at a certain temperature and using high pressure into the mold cavity after cooling and curing. Extrusion molding, also known as extrusion molding, is mainly suitable for molding thermoplastic plastics, and also suitable for forming parts with better fluidity and reinforced plastics.


The molding process is to use the rotating screw to heat and melt the thermoplastic raw material, extruded from the head of the required cross-section, and then set the type by the shaper, and then make it cold hard and solidify through the cooler, and become the required section. Before molding, the plastic must be fully dried.


When the material containing water enters the mold cavity, it will make the surface of the workpiece silver and tapelike flawed, even the phenomenon of water decomposition at high temperature, resulting in the deterioration of the material. Therefore, materials must be pre processed before injection molding in Dalian, so that the material can maintain proper moisture.


For an injection molding factory, the energy consumption occupies about 60% of the injection molding process. Therefore, it is an important way to effectively reduce the energy consumption of the injection molding machine. With the continuous improvement of the energy saving technology of the injection molding machine, the reduction of the overall energy consumption of the injection plant needs to be considered from the aspects of production management, processing technology and materials, and the production workshop. Because the melt plasticization and flow modeling of the molding materials are carried out in the barrel and die cavity, the mold can always be in a state that condenses the melt quickly or crosslinking, which is beneficial to shorten the molding cycle.
