polypropylene plastic folder Ultrasonic welding technology

The plastic materials of our common  folders are polypropylene, and there are two kinds of conventional welding positions. One is that the inner page and the middle seam of the cover are welded as follows, and the texture is clear and does not stick to the ultrasonic welding horn:

The other is the folder of the organ file package, which uses the double head welding technology. Compared with the middle seam, the welding tooling and equipment are relatively complex, and the design requirements of the welding joint are also high. The product to be welded by ultrasonic welding is manually assembled and placed on the welding bottom mold → the product is installed on the bottom mold for pressing, Manual pressing (optional) → the whole set of welding process is automatically controlled by the module after pressing the work button → the welding time is not more than 30 seconds (start action, welding, cooling and curing, mold rising) →

After welding, the products shall be combined beautifully and welded firmly → after welding, the finished products shall be unloaded manually.

This machine is equipped with 2 sets of equipment to independently adjust the welding state. It can be operated in a standing or sitting position. After adjusting the number of transducers, it can be used for welding similar (within the range) products. It is convenient to modify the program

To sum up, different plastic folders need corresponding production processes and mechanical equipment, and their welding plays an absolute role in the production process, which is very practical and simple.
