20Khz LCD Screen Ultrasonic Plastic Welding Machine
Description:
Ultrasonic welding equipment can be easily customized to fit the exact specifications of the parts being welded. The parts are sandwiched between a fixed shaped nest (anvil) and a sonotrode (horn) connected to a transducer, and a ~20 kHz low-amplitude acoustic vibration is emitted. (Note: Common frequencies used in ultrasonic welding of thermoplastics are 15 kHz, 20 kHz, 30 kHz, 35 kHz, 40 kHz and 70 kHz). When welding plastics, the interface of the two parts is specially designed to concentrate the melting process. One of the materials usually has a spiked energy director which contacts the second plastic part. The ultrasonic energy melts the point contact between the parts, creating a joint. This process is a good automated alternative to glue, screws or snap-fit designs. It is typically used with small parts (e.g. cell phones, consumer electronics, disposable medical tools, toys, etc.) but it can be used on parts as large as a small automotive instrument cluster.
Applications:
Toy industry: such as toy gun, water gun, telephone and rag baby etc.
Electronic industry: The gum case of watch, nylon watch band, calculator, sound box wraps hull, cell phone battery etc.
Car industry: Car light.
Pack an industry: Disguise box, PVC packing box, toothpaste tube etc.
General business ware: The typewriter color take, video cassette rack, tape box, computer disk etc.

Advantages
It can be applied to miscellaneous combination of material welding and allows welding of thick and thin sections.
Simplified welding of high and heat conduction materials such as copper, gold, aluminum, silver, etc.
he pressures used for welding are low along with low consumption power.
The time taken for welding is less and the width of deformed areas are thinner than that for the cold welding.
Disadvantages
Ultrasonic metal welding needs more power with the work piece as width and hardness increase exponentially.
This welding process is limited to lap joints.
It is dependent on material deformation under tooling.
It might create audible noise from the part resonance.
Ultrasonic welding is largely used in microelectronics devices and finishing technology and incorporated circuit element of interconnection.
