What is gas assist injection molding? The most effective method of apply- ing pressure to an injection molded part during cooling. Gas assist injection molding is a low pressure process which reduces the clamp tonnage required for molding. Gaseous nitrogen is applied internally, either directly into thicker sections of. What is Gas Assist Injection Molding? Gas Assist injection molding is a process enhancement to conventional injection molding, involving the injection of high pressure nitrogen gas into the resin melt stream immediately . injection molding machine into a fully capable MuCell molding machine. The upgrade consists of two In the plastics processing arena, gas-assist injection molding is a relatively new process that is experiencing rapid Figure 1.6 Gas injection through the machine nozzle .

Gas assist injection molding is a variation of conventional injection molding that can be easily retrofitted to an existing injection press by the addition of an auxiliary gas unit. The usual injection of molten plastic is assisted by the introduction of pressurized gas( usually nitrogen ) into the mold. The gas produces a bubble Designers can use gas-assist molding to create thin-walled parts. Such parts can be molded with low clamp tonnage, which reduces both tooling cost and required injection mold- ing machine size. The gas-assist technique is ideal for adding thick, hollowed-out sections to otherwise thin-walled parts. The process improves NitroJection Corp. is pleased to introduce an expanded product line now including recertified gas assist injection molding controls. These products PDF Product Sheet.
