Component Weight & Wall Thickness for component Manufacturing in GAIM

Gas assist injection molding (GAIM) has been developed to save material, shorten cycle times and to improve the surface aspects of thick-walled injection-molded parts. To control gas and using in plastic molding is impossible because gas gets burnt and blast at high temperature and pressure. But Nitrogen as inactive gas which rich available in environment made it, conceptuality to live.To check the Quality of Gas Assist Molded Part very difficult, because it depends on its Gas Channel Geometry and uniform wall thickness. These can be check only after cross section cut and those parts will be rejected. In GAIM, Part weight is very important criteria and now we need to established relation with part wall thickness. The GAIM study, trials, result, analysis and our experiment provides part weight have proportional related with part wall thickness. In the process of making components through Gas Injection Molding, it is noticed that part quality and strength is always a matter of concern when its wall thickness is not uniform or uncontrolled.
