Introduction to the injection molding industry
What is injection molding
A method of obtaining a molded product by injecting heat melted material into a mold cavity under high pressure and cooling it for solidification.
This method is suitable for batch production of complex shaped components and is one of the important processing methods.
Injection molding process
The injection molding process can be roughly divided into the following six stages:
Mold closing, injection, pressure maintaining, cooling, mold opening, product removal
The above process can be repeated to continuously produce products.
Trends in injection molding processes
Nowadays, the trend of processing technology is developing towards high and new technologies, including:
Micro injection molding, high filling composite injection molding, water assisted injection molding, mixed use of various special injection molding processes, foam injection molding, mold technology, simulation technology, etc.
Model of injection molding machine
Injection molding machines are divided into two types according to mold locking methods.
Vertical mold locking machines are called vertical injection molding machines, and horizontal mold locking machines are called horizontal injection molding machines.
The mold locking force is proportional to the amount of glue injected, and there is no formula to calculate it. The mold locking force of 100g of glue injection is about 25T
Parameters required for the Dongguan mold temperature machine option: temperature control medium: water or oil; The weight of the mold or the locking force of the injection molding machine; Mold temperature, mold inlet and outlet, and size.
