Why Gas Assisted Molding?
GAM is increasingly successful in providing molders and end users substantial benefit - both technical and economic - compared with conventional injection molding. To find out more about how GAM has revolutionised the plastics industry click here.
Gas Assisted Molding Process Methods
There are 3 alternative methods of applying internal gas molding, all of which use nitrogen gas as a medium for applying pressure to molten plastic in the mold - nitrgoen gas is used as it is chemically inert and therefore does not react with the molten plastic.
The three methods are detailed below:
All molding methods use the nitrogen gas as a medium for applying pressure to the plastic in order to improve the product surface finishes and to eliminate sink marks. Also the plastic is not subject to lamina flow whilst cooling, resulting in much reduced molded-in- stress, which otherwise can cause molding distortion of the product.
