Industry & Occupation
Classification
Summary
This occupation involves blending pigments or dyes into plastic raw materials to produce uniform colored mixtures. It manages product color unevenness and quality, and performs adjustments before feeding into the molding process.
Description
Plastic coloring workers are dedicated personnel who uniformly mix colorants into raw materials before molding in molding machines. They measure pigments or masterbatches, operate mixers or agitators to blend them, and manage and record hues and concentrations. They perform color matching for prototypes and quality inspections (color difference measurement) for mass-produced items to prevent color unevenness and foreign matter contamination. In the work environment, handling dust and chemicals requires wearing protective gear, safety management, cleaning, and maintenance.
Future Outlook
With the introduction of automation and IoT, the precision of mixing control improves. Demand for coloring technologies for environmentally friendly materials and high-function plastics is expected to expand.
