What factors need to be considered for ultrasonic welding design?

In life, the production of electronic products such as automobiles, home appliances, toys, and mobile phones that we see is indispensable for ultrasonic welding.

Ultrasonic welding refers to the use of high-frequency vibration waves transmitted to the surface of two objects to be welded. Under pressure, the surfaces of the two objects rub against each other to form a fusion between the molecular layers. Plastic welding refers to the welding of two separate plastic parts. Ultrasonic welding is suitable for all thermoplastics, amorphous plastics and semi-crystalline plastics. Also suitable for non-woven fabrics such as thermoplastic fabrics, polymeric materials, coated paper and hybrid fabrics.

The general applications of ultrasonic welding are:

Automobiles: Welding of large and irregular workpieces such as bumpers, front and rear doors, lamps, brake lights, etc. can be implemented by computer program control.

Home Appliances: Appropriate adjustments can be used for portable fluorescent shades, steam ironing doors, TV housings, recording, transparent panels for sound machines, power rectifiers, washing machine dewatering tanks, etc. that require sealing, firmness and aesthetics.

Packing: Sealing of hoses, connection of special packing belts.

Toys: Due to the use of ultrasonic technology to make products clean, efficient and strong, eliminating the use of screws, adhesives, glue or other ancillary products, reducing production costs and enhancing the competitiveness of enterprises in the market.

Electronics: The use of automation solutions allows users to achieve large-scale production while ensuring the quality of the products.

Ultrasonic welding design considerations

1. Ultrasonic welding methods: such as spot welding, embedding, riveting, welding, etc. In addition to ultrasonic welding, other welding processes are not available in MP3 or mobile phones.

2. Ultrasonic metal welding advantages:

1) The welding material does not melt and is not fragile.

2) Good electrical conductivity after soldering, very low or nearly zero resistivity.

3) The welding metal surface is required to be low, and the oxidation or electroplating can be welded.

4) The welding time is short and does not require any flux, gas or solder.

5) Welding without sparks, environmental protection and safety.

6) Low cost of mold and single piece process

8) Suitable for small batches or large batches

9) The welding node is very tightly sealed

10) Have a fast and efficient production cycle (less than 1 second)

Due to these advantages of ultrasonic metal welding and ultrasonic plastic welding, it is greatly convenient for manufacturing, and has an unusual effect, enriching various necessities in life.
