Product Description

15KHz 2000W ultrasonic welding generator transducer is

the horn ear with mask welding machine

Ultrasonic generator welding system comes with various protective functions for the greatest operational reliability, such as the intelligent cooling system and protection against short-circuiting, no-load operation and overloading.

Standard ultrasonic welding machine Non-woven standard mask machine, 20KHZ1200W-2000W, 15KHZ2600W-4200W ultrasonic welding machine Non-woven welding, plastic welding, welding, PVC leather spot welding, ribbon cutting, heat sealing and other multi-functional welding equipment, outer ear tape The mask machine fuses the elastic bands on both sides of the mask body in an ultrasonic manner to complete the finished earband mask. Only one operator needs to place the mask body on the conveyor belt fixture, and the rest of the subsequent actions until the finished product is completed The machine operates automatically, and the output of this machine is higher than that of ordinary earband machines.

Plane mask machine, automatic mask spot welding machine, ultrasonic mask machine, plane mask spot welder, disposable mask machine, non-woven mask machine, ear band mask machine, N95 mask machine, FFP2 mask machine and other mechanical equipment are required It is equipped with an ultrasonic generator. This supporting equipment is aliased as an electric box and an ultrasonic control box.

The main functions of the ultrasonic generator:

Used for welding and welding of non-woven masks, welding of front-end breathing valves of cup-shaped masks, welding of nose bridge line of cup-shaped masks, spot welding of ultrasonic ear bands, cup-shaped mask ears

Ultrasonic welding generator:-

Ultrasonic processing transducer stack is an industrial technique whereby high-frequency ultrasonic acoustic vibrations are locally applied to workpieces being held together under pressure to create a solid-state weld. It is commonly used for plastics, and especially for joining dissimilar. materials,embossing etc. In ultrasonic welding, there are no connective bolts, nails, soldering materials, or adhesives necessary to bind the materials together. SANDI new ultrasonic generators adopt international leading technology , which more stable and more intensive. adopt the imported international leading power tube drive, greatly enhance the stability of the product.
