High Precision Inline Color Measurement for Plastics Part Inspection

The colorCONTROL ACS7000 inline color measurement system from Micro Epsilon is used in many different fieldsĀ including use for demanding measurement tasks in the plastics industry. The system is considered to be one of the most precise inline color measurement systems in the world. Different sensor models are available to suit various measurement tasks in the plastics industry, e.g. for structured surfaces and transparent film.

Conventional color sensors struggle to provide accurate measurement results on curved or structured surfaces. The colorCONTROL ACS7000 inline color measurement system is specifically designed for these measurement tasks. Unlike conventional technologies, this system recognizes colors not just by comparing them to reference values, but also by using the reflection spectrum to ensure unique identification. Due to its very high measurement speed, the colorCONTROL ACS7000 is suitable for applications where colors and shades have to be examined on-the-fly and to very high accuracy like in the plastics and textile production, automotive industry and medical engineering. Due to the extremely high measurement accuracy, the system can also applied in laboratories.

In plastic injection molding, the exact color shade of the product is a critical factor. However, the color of the injection-molded part changes during cooling. The colorCONTROL ACS7000 inline color measurement system can, together with the ACS2 circular sensor, 100% inspect the warm, injected part as it is extracted from the mold. The system uses an empirically determined correlation of the color between warm and cold pieces which allows determination of the target color directly on the freshly injected part.

The inline color measurement system is also applied in non-contact monitoring of continuously produced, transparent film. It ensures that each millimeter of strip produced is identical in color. As well as identifying color fluctuations and streaks that can occur during production.
