A Proportion-Air QB2 pilots a high pressure ratio regulator for gas assist in this injection molding application. A polymer is introduced into the mold and the pressure control assembly forces the polymer into the mold and it then cools into the shape of the mold.
piloting a high pressure ratio regulator and a DST pressure transducer
control the pressure of a gas-assisted injection molding
. Gas pressures up to 7,500 PSI follows a partial polymer fill to create hollow channels and cover all the internal surfaces. The part has stiffness without additional weight.
Injection moulding (molding) is a very common process employed by numerous industries including: Glass, Plastics and Metals. Some of the products produced by this process include: bottles, bottle caps, automotive components, chairs, storage containers, gears and many other items we use on a daily basis.
This process requires repeatable and accurate pressure control – both, Proportion-Air specialties!
