gas assistant injection molding is one kind of mature technology in our company, which being used in our Gas assistant injection mould for more than 10 years, although gas assistant injection molding system began to be known by people during the two decades.
gas assistant injection molding can reduce and eliminate the sink mark on the surface, improving the quality and performance of the products.
gas assistant injection molding can save the plastic material and also reduce the cost.
Gas assistant injection molding system can fit for much smaller machine.
gas assistant injection molding can reduced molded stress and therefore improved dimensional stability without distortion.
gas assistant injection molding can reduce the cycle time, it is much shorter than the traditional processing.
Gas-assisted injection molding is a process that utilizes an insert gas (normally nitrogen) to create one or more hollow channels within an injection-molded plastic part.
The insert air push the certain volume plastic melt to fill around the cavity, due to the low pressure and high temperature, gas can get in each part of mould along the lowest resistance direction and when the gas through the molded part, which will give a force to push the surface of part close to the mould.
Gas-assist injection molding can full use of the air's flow performance to penetrate the molded part again, compensating for volumetric shrinkage until the part solidifies. This process is mainly keep the pressure around the plastic.
Finally the gas exhausted before mould opens.
Our company usually put Gasassistant injection molding system into chair mould, garbage bin mould etc. if clients have special request on his mold, we will research the possibility, and try our best to satisfy our clients.
