Based on the example of a front shell of LCD television,according to the request of rapid heat cycling molding(RHCM) technology,coupling with the software of Moldflow,the injection processing technology determined the number of gates was analysed,and the gating system design was optimized.

The basic ideas of designing plastic product and molds with gas-assisted injection molding technology are demonstrated with the mold designing of a color TV cabinet taken as an example for analysis.

Taking the processes of TV shell as an example, the essentiality is introduced by combination of new techniques(RPM) and traditional processes.
