💡 A Word from JOBPLOY
Sangjin Polymer Co., Ltd. handles the process of crushing plastic by-products and reproducing raw materials through high-temperature extruders. Since the process involves managing extruder heat, moving heavy raw material bags, and crushing and mixing, wearing protective gear such as safety shoes and gloves is very important. You can adapt smoothly if you are well-versed in simple Korean instructions used on-site and follow safety rules when operating machinery.
