*必 must will gate design in thick most large 区域. * gate can in high force 区域附近. * for/regarding long parts, especially is reinforcement type mixed material, electrical machine can can, 应该沿纵 toward is toward or in in 心设置 gate. * if in or above type 腔, parts and gate and 沿注道 for 称布置. *轴 toward for parts, gears, 盘, sheet/slice and other, most good use sheet/plate gate and in in 心设置 gate, or in sheet/plate injection molding parts mold upper more gate, obtain good flow features. * has 一体式铰接 parts in gate 时, make combined 线远离铰接点. in 任何情况 lower. 都应避免 will material flow separation design in 铰接点附近. *杯形 parts (例如 small housing/shell 体, electrical container and other) gate design in base/seat 附近, 以避免 generate gas gas 穴. * for/regarding tube/pipe parts, make material filling 一端 圆周, rear again filling tube/pipe full long separation. this 样, can make material flow front 沿避免 generate for 称形状. * in 塑孔栓, type and its it metal parts 周围镶嵌模塑时, resin can in parts flow, can can decrease/reduce parts 位置 不准确. * for/regarding can defect (例如 gate 痕迹) outer surface, can will gate in internal, use 遂道式 gate material elastic upper. * in complex parts and tool has different more type injection molding parts mold upper, gate 位置应尽 can can make material flow front in filling process in generate short 暂停止. this 建议显然并不 can cover/cap has application 情况, in 实际情况 in is need 妥协以求 balanced, this 取决于 specific made process complex degree.
