In this study, we investigated the possible use of an aluminum alloy mold for high-cycle production in injection molding by carrying out comparative tests on an aluminum alloy mold and an S55C mold. The ABS resin used during injection has lower temperatures when using the aluminum alloy mold. However, the difference in mold material does not affect the amount of temperature increase during injection. The pressure in the mold is lower and the weld depth is larger when using the aluminum alloy mold. The aluminum alloy mold showed smaller warpage. When comparing warpage, the aluminum alloy mold achieved a smaller warpage at shorter cooling times. It is clarified that the aluminum mold is a good candidate for reducing cycle time.
