20khz Piezoelectric Ceramic Ultrasonic oscillator For Ultrasound welding

Advantages of Plastic welding vs. Adhesives

• Plastic welding generally does not require using any consumables. Adhesive joining does, which consumables are messy and often hard to contain.
• Plastic welding generally does not require intensive surface preparation steps, which adhesives often do.

Advantages of Plastic Welding vs. Mechanical Fasteners

• A weld is permanent, which prevents tampering with the internal components.
• Plastic welds are much lighter than mechanical fasteners.
• Welding can provide a leak tight, air tight seal, mechanical fasterners cannot (unless an o-ring is also used).​

Advantages of Plastic Welding vs. Snap Fits

• Welding works on a greater variety of materials. Snap fits are generally only for very flexible materials.
• Welding can provide a leak tight, air tight seal, snap fits cannot.

20Khz transducer Parameter datasheet

Description:

Ultrasonic Transducer for Welding, Drilling and Polishing High-power ultrasonic drilling machine, welding machine, polishing machine vibrator have small machinery loss, high efficiency electricity and sound transfer, big swing and less heat.

The transducer converts high-frequency electrical energy into high-frequency mechanical vibrations. And it contains several piezoelectric ceramic discs sandwiched under pressure between two metal blocks. Between each disc is a thin metal plate, which forms the electrode. When a sinusoidal electrical signal is fed to the transducer via the electrodes, the discs expand and contract, producing axial vibrations.

15Khz transducer widely used in high power welding&sealing system.Piezoelectric transducer is the electric charge that accumulates in certain solid materials in response to applied mechanical stress. It is key point of all ultrasonic equipment.The transducer decide the property of the machine.We can supply transducer, also transducer with house and booster.​

To design and fabricate the transducers according to customers' requirements.
