About Us

Ruian Delong Auto Parts Co., Ltd

Rui'an Delong Automotive Parts Co., Ltd. was founded in 2007. Its predecessor was non-standard screw parts. Since 1985, it has been producing various types of non-standard automotive parts. In 2007, it switched to producing automotive temperature sensors. 


Currently, we have a 10500 square meter site and own our own factory. Our annual output is 5-7 million pieces, and the company has been in a period of development and growth. At present, the product series includes water temperature sensors, air temperature sensors, oil pressure switches, and fan temperature control switches. At present, there are approximately over 1000 product categories, all of which are self-made parts with no purchased products. Our company currently has three automatic lines for producing water temperature sensors and fifteen automatic CNC production equipment. In addition, our company plans to invest more funds this year for various equipment updates, experimental equipment upgrades, and software improvements.


 We are currently mainly focused on Europe and the United States, and will vigorously develop categories in these two markets in the future to better meet the variety needs of our customers.
