What Does A Sewing Machine Go Through Before It Leaves The Factory?

Do you know what a high-quality sewing machine goes through before it leaves the factory?

Market researchers find out the most urgent needs of garment factories based on customers' feedback and market insight every day; R&D personnel continuously analyze and decompose the needs, overall program design, 3D design simulation, drawing, prototype trial installation, debugging and testing; from research feedback, planning to R&D and design, and then to production and acceptance. ......
It seems like a simple sewing machine, but in fact, each process is extremely tedious and meticulous, and there is no room for sloppiness!

At the end of the sewing process, the thread is too long, and it takes a lot of labor and waste of thread to trim it twice;
Thread cutting is cumbersome and easy to injure, making it difficult to recruit thread cutters;
Threads are all over the factory, affecting the working environment ......
After the layers of research, we found out that the thread is too long and the starting seam has a bird's nest is the biggest challenge faced by the current garment factories, and the corresponding solution.
During the research and development period, there were mountains of drawings, boring and repeated experiments, reliable testing of the electronic control program, the selection process of the double knife parts, the development and improvement of the types of presser feet, and so on.

In order to improve product quality and adapt to different garment process requirements, the R&D team has conducted selection and testing again and again.
