Nanjing Tianyi Automobile Electric Manufacturing Co,. Ltd

Established in 1999, Nanjing Tianyi (TY) is a specialized manufacturer of automobile parts such as ignition coils, ignition cable sets, insulating sleeve and resistor for spark plug. Located in Dongping Industrial Park of Lishui County in Nanjing, just 10, 0.5 and 1 kilometers away from Nanjing Lukou International Airport, Jiangsu Yanjiang Highway and Ninghang Highway individually，TY enjoy convenient access to major transportation networks. 

The company occupies about 17,350 square meters area and owns many advanced facilities. In the factory, workshops for rubber boot and subassembly, resistor, ignition coil, non-framed coil and molding are all established.

The rubber boot and subassembly workshop adopts rubber injection molding machine. The daily production capability has been over 100 thousand. These products are mainly applied in varieties of automobile and motorcycle engines.

With plastic injection molding machine in the resistor workshop, the daily capacity can reach over 80 thousand. These resistors are mainly used in auto engines and boiler ignition system.

TY autonomously produce all components of ignition coil, garantee long life, huge power and stable performance by strictly quality control in each working procedure. Nowadays, the annual production capacities of ignition coil and ignition cable have exceeded 800 thousand and 500 thousand sets respectively. 

Non-frame coil is used for special type of relay, instrument and meter. It has been in military enterprise for 10 years. Now the annual output has been reached 100 thousand. 

Nowadays, the factory established its own machining center, which can develop and produce all moulds for ourselves and our customers. Not only can production period be shortened, but also the company can enjoy higher efficiency and more economy. 

In the testing center, the company has professional equipments to test rubber products such as IC high-voltage balance, high and low temperature aging test box, electronic tensile-testing apparatus, silicone hardness tester, infrared tester and salt fog tester. In order to the quality of ignition coils, there are high-voltage testers, stimulant ignition equipment and scientific devices for testing coil resistance, inductance, number of turns, insulation and short circuit.

TY export products to the Europe, North America, Middle East, Southeast Asia and Taiwan. The company has passed the ISO/TS16949 certification. In the spirit of honesty, the company has won the favor of customers. In the future, the company will continue to progress in order to achieve more achievements.
