The stringer product includes three series: CHS/D conventional type, MS multi-functional type and CHR shingled type, all of which share the features of high production capacity, strong compatibility, short mechanism switching time and good accuracy. With development of new PV module technologies and changes in customer requirements, new functions are incorporated into the stringer machine, such as the LRF laminator, which, using a leading technology in the market, can increase the output power of module by 1.5-2%; the string detection system, which, using line camera technology in this field for the first time, can greatly improve the imaging resolution and get a strong detection stability; the EL detection system, which, using deep learning algorithm, can effectively improve the detection accuracy and reduce batch production failure.

In 2017, ATW extended business to upstream of the PV industry chain, and successfully launched the automatic wafer sorting machine, which broke the long-term monopoly of imported products and was superior to the imported machines in measurements of wafer thickness, saw marks, etc. due to its pioneering use of 3D vision and other new technologies in this field.

In 2019, ATW introduced a light induced annealing furnace, which can repair inner defects of the P- or N-type cells with LED injection technology and improve cell efficiency.

In 2020, ATW developed an up-to-date model of automatic PV cell stringer which achieved 6400 cells per hour output and accommodated 156 to 230 mm PV cells. The unqualified ratio is lower than 1% in average. ATW has remained stable growth based on the advanced technology and the updated products.

From the very beginning of foundation, ATW has been working hard on technology development and market expansion in the PV industry. ATW's mission, building smart factory with new technology, is continuously motivating ATW staff to make unremitting endeavor and to achieve sustained excellence on the cause.
