A color masterbatch assistance system for optimizing product color by masterbatch addition in injection molding of post-industrial recyclates
Abstract
In injection molding, ensuring consistent optical part quality, in particular achieving identical color across the parts produced, is crucial. In the context of processing recycled materials, variations in the input material streams can pose challenges, requiring color masterbatch content to be adapted inline if a predefined reference color is to be achieved. This study presents a color assistance system that uses a sensor to measure the color of injection molded parts and to determine the optimal amount of masterbatch to be added for achieving a specified color for a defined material input stream. Testing of the system focused on post-industrial recyclate which had a color in the second color quadrant in the CIELAB color space. The system proved effective in regulating masterbatch contents to improve color consistency and can be employed for quality assurance in the injection molding process, particularly when using recycled materials.
