Injection molding is a process for producing parts made of thermoplastics or thermosets. In injection molding, the plastic is heated and melted in the barrel of the injection molding machine, and when it is in a flowing state, the plastic is compressed and moved forward under pressure by a plunger or screw. injection molding services Under the pressure of plunger or screw, the molten plastic is compressed and moved forward, and then injected into the closed mold with low temperature through the nozzle at the front of the barrel at a fast speed. This molding method is an intermittent operation process
. What is injection molding?
Injection Molding is a method in which hot melted material is injected injection molding manufacturer into the mold cavity at high pressure and then cooled and cured to obtain a molded product. This method is suitable for mass production of complex-shaped parts and is one of the most important processing methods.
The injection molding process can be roughly divided into the following six stages at injection molding factory.
1. Closing the mold
2. Injection
3. Holding pressure
4. cooling
5. mold opening
6. Product removal
