Gas Assisted Injection Molding

Gas assisted injection molding, also known as gas injection moulding, is a new
gas injection moulding process. It is one of the most important developments in
the injection molding industry since the advent of reciprocating screw
injection machines. Gas-assisted injection molding process is an extension of
injection molding. It is developed on the basis of injection molding technology
and structural foam injection molding. it can also be considered as a composite
of injection molding and hollow molding. In this sense, it can also be called
"Hollow injection molding". The principle is to replace the resin pressure in
the cavity with a relatively low-pressure gas during the pressure holding phase
of the original injection molding. Gas-assisted injection can be achieved by
simply adding an air supply device to the existing injection molding machine.
The gas supply device is composed of an air pump, a high-pressure gas
generating device, a gas control device, and a gas nozzle. The gas control
device uses a special compressor to continuously supply gas, and is controlled
by an electronic control valve to keep the pressure constant. There are usually
3 levels of pressure. A set of gas control device can be equipped with multiple
injection molding machines.To achieve this, whole gas injectino moulding
process required closely connections. 
The gas generally used is nitrogen. Gas pressure and gas purity are determined
by the shape of the molding material and product. The pressure is generally 5 ~
32MPa, the highest is 40MPa.
