This model is specifically developed for hardware components (movable corner brackets). For manual assembly of movable corner brackets, one needs to manually install nuts, screw rods, and finally use an air or electric wrench to tighten the screws. All of this is done manually, making the process cumbersome and inefficient. Our company, in response to customer requirements and market demands, has invented and designed an automatic screw machine. It has a wide range of applications and can process 95% of the corner bracket products on the market. This machine realizes automatic feeding, automatic arrangement, and automatic tightening of screws. The tightening force can be adjusted. It can process 30-40 movable corner brackets per minute. This is a patented product. Counterfeiting will be prosecuted!
