Background: A well-known motor enterprise in China produces new energy vehicle drive motors. 100 motors per line per day by 2020.

The wiring link of enameled wire adopts solder process, and the lead size is between 30-70 square. The steps are as follows: remove the patent leather - dip the flux - apply the tin - hit the terminal, which requires three manual workers.

Due to the hidden danger of instability in the case of high temperature or jitter, and in order to save labor, improve efficiency and expand production capacity, the motor company learned that the resistance welding process has more advantages in the problem of enameled wire wiring and has been verified by the market, so it contacted the major resistance welding equipment companies, played samples, and did a series of tests and small batch production.

Our company Jianhua precision stands out among the equipment manufacturers, and has the honor to become the supplier of the motor enterprise.

After welding the enamelled wire of the new energy drive motor with the resistance welding process:

one) Compared with the previous soldering process, the efficiency is increased by 30%-50%

two) The production capacity has been improved, and at present, a line can welder about 300 motors per day

three) There is no need to remove patent leather and tin, saving 2 labor and saving costs for the enterprise.

four) The quality is better, and the hidden danger of tin removal under high temperature or shaking existing in the original soldering process is got rid of. More market competitiveness.

We also thank the company for our trust and cooperation, so that we can make greater progress and development in the field of motor lead welding!
