💡 A Word from JOBPLOY
Yushin Synthetic Co., Ltd. is a stable company specializing in plastic injection molding that supplies plastic food containers to large corporations such as Daesang Chungjungone. The main tasks consist of inspection, finishing, loading, and packaging of plastic containers coming out of the injection machine. Due to the nature of the injection process, heat and noise from the machinery may occur, so wearing basic safety gear and following workplace rules are important. Since the process is standardized and automated extractors are introduced, it is a suitable environment for foreign workers to adapt quickly and work long-term if they have diligence and a meticulous attitude toward quality inspection.
