The team that the founder Leo ho worked with was initially doing hardware and electromagnetic research and development, and later the technology was applied to electromagnetic locks, electromagnets, and we applied electromagnets to industrial sewing machines, which is what you see that our products are based on technical research and development rather than simple assembly, of course, other parts and accessories are from stable and reliable supplier support.
