Summary
Processing technician who molds hollow products by placing resin in a mold, heating it while rotating.
Description
Rotational molding workers charge resin powder or pellets into molds and manufacture hollow plastic products by heating and rotating. They perform mold attachment and replacement, material weighing, machine operation, temperature control, and rotation speed adjustment. After molding, they handle post-processing such as cooling, demolding, trimming, and quality inspection. They are also required to maintain equipment, adjust operations based on production plans, and participate in 5S activities.
Future Outlook
Demand for hollow products such as plastic containers, tanks, and automotive parts remains stable, with moderate growth expected due to expansion in new markets like IoT device cases and fuel tanks. However, skilled worker shortages are a challenge, and equipment automation and multi-skilling are anticipated to advance.
