Nanjing Keya Company was founded in 1993. It was a Sino-foreign joint venture in the early stages of its establishment. The investors were Jiangsu Science and Technology Commission, Macau East Asia Industrial Company, and Nanjing Extrusion Machinery Research Institute of the Institute of Chemical Machinery of the Ministry of Chemical Industry. The company's main products are SHL-60 building block type homogeneous twin screw extrusion unit, which is developed by Liu Guangzhi, then director of Nanjing Extrusion Machinery Research Institute. , The project won the National Science and Technology Progress Award in 1990, thus opening the precedent for domestic same-direction twin-screw extrusion units.

In 1999, in line with the development of the domestic plastic compounding industry, Keya took the lead in upgrading the first generation domestic model with a screw speed of 300rpm to a second generation of same-way twin screws with a screw speed of 600rpm, and was specially titled by the People's Daily in 1999. The report says "There is a little giant in Nanjing." By 2003, Keya had grown into a leading enterprise with an annual production of 350 sets of hosts, sales of 130 million yuan, and profits and taxes exceeding 10 million yuan.

Nanjing Keya Company, established in 1993, has experienced storms and has sold more than 8,000 sets of same-direction twin-screw extrusion units of various specifications to the world over more than 20 years (of which 20% of them were sold). The impressive performance not only laid the foundation. Keya’s brand effect on a global scale, and more importantly, Keya’s high-quality and low-priced equipment has promoted the development of my country’s plastic modification industry and promoted the widespread application of my country’s plastic products in all walks of life. The establishment of Nanjing Keya Group will surely be committed to technological innovation, precision manufacturing and perfect services of same-way twin-screw extrusion units, and make due contributions to the foundation and development of China's industry!
