What Are The Differences Between Ultrasonic Plastic Welding Machines With Different Frequencies?

There are many brands of ultrasonic plastic welding machines in the market, including domestic and foreign. At present, foreign equipment and technology are relatively advanced. Different brands of ultrasonic welding machines have different welding effects due to different equipment structures and materials. Ultrasonic automatic welding machines of the same brand have different welding effects due to different equipment structures and materials. Among them, different frequencies of ultrasonic plastic welding machines will bring obvious differences.

The common frequencies of ultrasonic plastic welding equipment are 15KHz and 20kHz. Today, we can understand the differences of welding machines with different frequencies through these two models:

1. Different shapes: the sensor of 15KHz ultrasonic welding machine is generally inverted cone type, and the specification of screw hole is m16x1 The sensor of 0-tooth, 20kHz ultrasonic welder is generally cylindrical with small diameter, and the empty specification of screw is 24 teeth at 3 / 8 of the British system.

2. Different noise: when the frequency of ultrasonic plastic welding machine is lower than 20kHz, the noise during ultrasonic welding will become larger.

3. Different ultrasonic molds: 15KHz ultrasonic welding molds are generally about 17cm long, and 20kHz ultrasonic molds are about 12.5cm long.

4. Different welding time: the welding time of 20kHz ultrasonic plastic welding machine is relatively short, which can speed up the welding speed of products.

5. Different welding products: ultrasonic plastic welder with 20kHz or higher frequency is suitable for precision, ultra-thin and fragile plastic parts, such as SD card and crystal products. 15KHz ultrasonic plastic welding device power is more suitable for larger workpieces.

Generally speaking, the higher the frequency of ultrasonic welding machine, the better the welding quality and the higher the sales cost. However, in the actual production and processing, the higher the frequency, the better. We should choose the ultrasonic welding equipment with appropriate frequency according to the production situation of our own factory, so as to save the procurement cost of equipment on the premise of ensuring the welding quality. If the frequency of some ultrasonic welding machines is too high and the welded workpiece needs low-frequency welding equipment, the welding quality can also be ensured by adjusting relevant parameters, so that the high-frequency ultrasonic plastic welding machine can also have the effect of low-frequency welding.
