Nanjing Chenming Electronic Technology Co., Ltd. is a private high-tech enterprise with 20 years of experience in the research &development, production, and sales of current and voltage monitoring products. We have obtained ISO9001:2015 and IATF16949:2016 certifications. We provide current and voltage detection solutions for the national power grid, mobile communication base stations, urban subways, intercity high-speed railways, locomotives, and other fields, as well as the aerospace and industrial automation industries. Our products are mainly exported to Asian and European countries.
We currently have 105 personnel, 15 R&D technical teams, accounting for 14%, 70 production personnel, and 12 personnel in comprehensive department. In 2015, Cheemi Technology Co., Ltd. was established in Hong Kong, mainly for international sales of sensors and providing procurement services to global customers.
We have 18 patents, including 3 invention patents. The main products are current and voltage sensors, AC/DC leakage current sensors, proximity sensors, temperature sensors, pressure sensors, etc., and have passed CE and RoSH certificates. The company covers an area of about 20000 square meters, with a production workshop of 10000 square meters. There is a dust automated SMT production lines; Other production lines include two semi-automatic reflow soldering production lines, three conventional product assembly
production lines, two special product assembly production lines, one semi-automatic debugging production line, and one fully automated glue filling production line, a total of 12 production lines to ensure the daily output of about 12000 sensors of various types.
In order to provide customers with better one-stop service, we have established a procurement center, which mainly provides procurement services for electronic components other than sensors, and providing customers with the best logistics and transportation channels, saving logistics time and operating costs, and achieving a win-win situation.
