35KHZ, 30KHZ, 28KHZ, 20KHZ, 15KHZ ultrasonic welding dies, welding head, the die is different depending on the product made into a mold, mounted on the respective frequency matching of welding machines, and with the use of ultrasonic welding machines. Ultrasonic die main functions: 1. Depending on the shape of products, designed to make sure welding mold different specifications. 2. Small space and easy changeover. 3. The one-piece upper and lower dies separated design and optimization of mold caused due to product obsolescence debugging. Specifications: Model YJM-15KHZ, 20KHZ, 30KHZ, 35KHZ dimensions of non-standard ultrasonic welding can be applied to all products.
