There are many methods of plastic molding. Injection molding is one of them. Injection molding is also called injection molding, which is called injection molding for short. It is a main molding method of thermoplastic. Because it has the advantages of wide application, short forming cycle, high production efficiency, good production conditions, easy mechanization and automation, it plays an important role in the whole plastic forming process.Injection molding refers to injecting granular or powdery plastic from the hopper of the injection machine into the high-temperature barrel, heating, melting and plasticizing to make it a flowing melt, and then under the high pressure of the plunger or screw of the injection machine, it passes through the nozzle at a large flow rate and is injected into the mold cavity. After a period of pressure maintaining, cooling and shaping, When the mold is opened, the Plastic Parts with certain shape and size can be detached from the mold cavity. In this way, the time required to complete an injection cycle can range from a few seconds to tens of seconds, which mainly depends on the size and thickness of the workpiece.

Anqing Petrochemical Electric Instrument Department to take a number of measures to take the initiative to do a good job in the control valve of acrylonitrile production plant maintenance work over the past year, the Ministry of instrument three workshops a total of 116 cases handled a total of 116 to repair 12 units, not only to meet the urgent need for plant production, It also saves about 300,000 yuan for enterprises to save money on maintenance. Because of the need of internal reform, after the cancellation of the original fitter's class, Anqing Petrochemical Electric Instrument Department will be responsible for the maintenance of instrumentation and equipment, such as regulating valves, into the scope of maintenance of other classes. Instrument three workshops assume the second largest number of regulating valve, the full range of control of the process medium both corrosive substances, but also toxic and harmful substances, all forms of control valve can be found here. To this end, a meter three workshops take the initiative to take the initiative on the one hand, to increase the control valve maintenance efforts, on the other hand workers learn from each other fitter knowledge and improve the technical level. The recovery valve more direct and corrosive acid and alkali process media contacts, the occurrence of more frequent problems, team members work overtime, ready to solve the problems that arise, to ensure the safe operation of the device.
