Abstract

Gate is an important part of the injection molding process which has the main objective of transferring liquid plastic into the mold chamber. There are various types of gates, one of which is the edge gate. The most simple and flexible gate of other gate types. However, in the production process, the mold uses the edge gate type, the part that comes out of the injection molding machine is still attached to the runner. Thus, rework is required by the operator to separate the plastic parts and runners which can extend the cycle time and can cause product defects in the form of overcuts. This research was conducted to determine the function of mold modification which can make runners and plastic parts separate automatically after leaving the injection molding machine and its effect on the cycle time in achieving the target output. This research was conducted through a process of observation and interviews before making designs and autodegating modifications to mold doors. The results of this study indicate that the autodegating modification of the mold door can cut the plastic part and the runner apart automatically. In the production process, the rework process by the operator is no longer there, the part after leaving the injection molding machine is immediately packed by the operator. The production process cycle time was reduced from 34 seconds to 30 seconds so that the output target was quickly achieved.
