Anhui Zhongke Optic-electronic Color Sorter Machinery Co., Ltd.

Anhui Zhongke Optic-electronic Color Sorter Machinery Co., Ltd. calls Hefei, China home, and they’ve really made a name for themselves in the world of intelligent sorting equipment. You’ll find their massive operation spread across 100,000 square meters, backed by a $20 million investment. Inside, there’s a high-tech production workshop—27,000 square meters of it—plus a 25,000-square-meter research building. That’s a lot of space dedicated to coming up with new ideas, building at scale, and staying ahead in the industry. After more than 23 years in the business, Zhongke isn’t just another factory. They’ve grown into a major player with over 900 employees and annual sales topping $150 million.

Quality runs right through everything they do. Zhongke has bagged all the big certifications for quality, environmental, and occupational health management. Their popular “AMD” series has even earned the European Union’s CE certification, which just underscores their drive to meet international standards. With tight quality control and strong service, Zhongke has pushed the AMD brand out into markets all over China and beyond. Their motto says it all: “Optical sorting, we are everywhere.” And they back it up—AMD color sorters consistently rank among the top three in the market and have made their way to over 100 countries and regions.

Innovation is a big deal here. Zhongke set up a dedicated R&D center and got recognized as both the “Anhui Enterprise Technology Center” and a “Postdoctoral Scientific Research Workstation.” They’re not going it alone either—they teamed up with Hefei University of Technology to launch the Intelligent Identification and Sorting Engineering Technology Center. With nearly 48 patents to their name, a bunch of high-tech products, and a hand in setting local industry standards, Zhongke isn’t just following trends—they’re setting them. The AMD brand has picked up big awards, like “China Famous Trademark” and “Famous Trademark of Anhui Province.” The government and industry groups have honored the company more than once, and since 2015, Zhongke has been listed on the Shanghai Stock Exchange under stock code 603011.
