The new electric heating is generally required to reach the set temperature 30 minutes before operating the screw. If the machine stops for more than half an hour each time, it is best to close the blanking port and shoot clean the material in the cylinder, and set the insulation Avoid foreign matter falling into the barrel and damaging the screw and barrel. Prevent metal debris and debris from falling into the hopper. If the recycled material is processed, magnetic hopper should be added to prevent iron filings from entering the barrel.

What is an injection molding machine? It is the thermoplastic or thermosetting material using plastic molding mold to make plastic products of various shapes of the main molding equipment. Divided into vertica l, horizontal, full electric. The injection molding machine heats the plastic and applies high pressure to the molten plastic, causing it to shoot out and fill the mold cavity. History of injection molding machine. The injection molding machine was invented in the United States in 1872 and has a history of 130 years, but the screw injection molding machine has been developed in the past 50 years and become the most commonly used injection molding machine in the industry today. At present in the engineering plastics industry, 80% of the use of injection molding. The

Shrinkage rate Forms and calculations of thermoplastic molding shrinkage As mentioned above, the factors affecting thermoplastic molding shrinkage are as follows: 1.1 Thermoplastics In the molding process, due to the volume change from crystallization, strong internal stress, large residual stress frozen in the plastic parts, strong molecular orientation and other factors, thermoplastics have a larger shrinkage rate, wide shrinkage range and obvious directivity compared with thermosetting plastics. In addition, the shrinkage rate after forming, annealing or humidification treatment is generally larger than thermosetting plastics. 1.2 Characteristics of plastic parts During molding, the molten material contacts the surface of the cavity and the outer layer is cooled immediately to form a low-density solid shell. Due to the poor thermal conductivity of plastic, the inner layer of plastic parts

For the traditional injection molding machine, how to expand the space of energy saving? The energy consumption of the machine is mainly reflected in the following parts: (1) Electric energy consumption of hydraulic system oil pump; (2) The power consumption of the heater; (3) Power consumption of circulating cooling water pump. The power consumption of hydraulic oil pump accounts for more than 80% of the total power consumption of injection molding machine. So, what are the energy-saving transformation methods of injection molding machine?
