The effect of Gate type on Injection Molding of Automotive Bumper

자동차 범퍼금형에서의 게이트 형상이 제품 성형에 미치는 영향

Injection molding process is one of the processes that can mold plastic product as low cost. However, manufacturing process of automobile bumper mold has lots of trial and error. Especially, desiging of a huge mold such as bumper mold is needed to establish a design standard for runner system. In this study, CAE was conducted to observe the variation of melt-flow by changing runner and gate type in automobile bumper mold as preceding study for a standard design of runner system.
