How to weld medical filters with ultrasonic welding machines  

Ultrasonic Welding Machine can be used for air filter, medical liquid filter, photo machine ink filter welding.

Such products are generally MADE OF PP, and the two pieces of plastic are filled with PTFE diaphragm or unidirectional air filtration membrane or high-density steel mesh. The plastic box diaphragm needs to be welded together at the same time, and the welding around the diaphragm is firm, and there is no leakage of water and air.

According to the nature of the use of plastic shell materials have PP, PC or PE, welding such products, because the plastic material is relatively difficult to weld, the welding time should not be too long, the amplitude should not be too large, a long time will cause product surface scars, welding time is too short, then the internal welding is poor; At the same time, the amplitude of ultrasonic waves should not be too large, and too large the amplitude will cause the interface column of the filter to break. In summary, to find a suitable power, amplitude suitable ultrasonic welding machine. DIZO 15k, 20K Ultrasonic Welding Machine can complete the welding of the filter of PP material in a small amplitude and a short time, and the product after welding has good sealing, no water leakage, the product surface is not rotten, and the inlet and outlet joints are not broken.
