Injection Machine: Important role in the process of injection molding machineby Richard Smith Plasticmoldingline
An injection molding system plays an important role in the process of the injection molding machine. Heating system will affect the molding temperature directly for a good plastic product. Injection molding is an engineering technology. It may change in the plastic material into useful products to the original performance plastic.
Injection molding process is one of the important factors that affect the rate of melting and cooling temperature, pressure and duration of each corresponding action. Then check the temperature during the injection molding process is very important. We can analyze the temperature in three parts. They are the injection machine screw temperature, nozzle temperature and the mould temperature. Screw temperature and the nozzle temperature mainly affect the ability to laminate plastic and moving. And the mold temperature primarily affects the movement and cooling plastic. Nozzle temperature is generally lower than the screw temperature. Mold temperature affect more on the plastic inner product performance and apparent quality.
The pressure of the injection process is to laminate the pressure and the injection pressure. They are directly affect the plastic laminate and product quality. Generally, the holding pressure is smaller than the injection pressure. We should do depend on the plastic used to achieve better physical performance and appearance.
