Optical color sorter date back to the 1930s and were used initally to improve quality and safety of food products. Growth in PET recycling paved the way for their use in plastics—first to remove green and other colors from clear PET in beverage containers, then to remove PVC and other polymers that may be the same color as the clear PET, but exhibit different melt temperatures.
Now, though, optical sorting is a viable option for any processors or recyclers that generate moderate to high volumes of regrind and would like to reintroduce it into their own feedstock or sell it on the market at premium prices. The driving force that has opened this technology to the industry at large is the introduction of compact, user-friendly, full-color, camera-based sorting machines.

Color sorter is a great initiative for plastic industry, to solve the problem of color separation. After the plastic is broken and cleaned, various colors are mixed together, which makes it difficult to reuse. Only by separating the colors can we effectively improve the reuse rate and truly achieve recyclable development.

Plastic color sorter, under the precise program setting, is more efficient than the human eye to continuously carry out precise sorting of small color differences.

GroTech plastic color sorter is used for sorting through the color difference of materials. Optical Sorting With Professional Industrial Wide View Camera Lens,Top Chromatic CCD Sensor,High Reliability And Long Life Source ,American Super Speed FPGA Processor, is a high value utilization technology in renewable resources industry. According to the material customization algorithm, a machine can separate many kinds of materials.

GroTech plastic color sorter can separate each color, select a specific color, and separate transparent and opaque materials. If there is any color difference, they can be sorted.
