ABS PP Ultrasonic High Frequency Plastic Welder Plastic Welding Machine For PSA Grading Card Plastic Slabs Case Sealing

Specification:

Description:

Ultrasonic welding equipment 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.

Advantage:

1. Ergonomic design

2. Can be controlled manually, or by foot switch

3. The blade is not sharp, safe and durable

Equipment maintenance:

1. Attention should be paid to the following matters when repairing ultrasonic generator (driving power supply).

Turn off the vibration power supply and remove the power plug. Remove the cover and discharge the large electrolytic capacitor. There is also high voltage residual electricity on the transducer. It should also be discharged (directly connected to the positive and negative poles with wires).

2. grounding to be thorough.

3. Confirm whether the power switch is OFF before connecting the power plug.

4. In order to prevent hearing damage during vibration, the processor should use hearing protector.
