Ultrasonic Assembles Medical Device

Ultrasonic welding is widely used in medical equipment worldwide, including drug delivery equipment, orthopedic surgical instruments, thoracic drainage devices and catheters. As the equipment becomes more and more complex and precise, the ultrasonic assembles medical device plays an increasingly important role in the medical industry

The successful application of ultrasonic plastic welding technology in the medical device industry depends on the strict high cleanliness requirements of the medical industry for product grids. Another factor is the increasing miniaturization of medical products. The accuracy required for medical microfluidic and diagnostic equipment can only be achieved through ultrasonic technology.

FAQ:

Q：Analysis of the reasons why ultrasonic welding achieves water tightness and air tightness

Sometimes when the ultrasonic plastic welding machine is welding products, the welded products do not meet the standard, and the water tightness and air tightness do not meet the standard during the test. When analyzing the reasons, the product structure design is reasonable, and the power of the ultrasonic plastic welding machine is enough. What is the reason?

1： The falling speed and buffer of ultrasonic plastic welding machine are too fast: this forming speed will make the dynamic pressure plus the gravitational acceleration flatten the ultrasonic waveguide fuse line, so that the fuse line can not play the role of fuse guide, forming a false phase fusion.

2： The fusion time of the product is too long: plastic products receive too long heat energy, which not only melts the plastic material, but also causes the coking phenomenon of plastic tissue, resulting in sand holes, from which water or gas infiltrates, which forms the phenomenon

that the water tightness and air tightness do not meet the standard.

In short: when we weld plastic products, if the welding effect is not up to standard, on the one hand, we can find the reason from the ultrasonic plastic welding machine itself, and achieve the welding purpose by adjusting the parameters of the ultrasonic plastic welding machine and the ultrasonic mold. On the other hand, we can find the reason from the material, structure and fuse line of the product.

Q：What are the common misunderstandings of Ultrasonic Assembles Medical Device?

Misunderstanding of ultrasonic output power; The size of ultrasonic output power is determined by the diameter, thickness, material and design process of piezoelectric ceramic sheet. Once the transducer is finalized, the power will be finalized. Measuring the size of output energy is a complex process.

It is not that the larger the transducer, the more power tubes used in the circuit, the greater the output energy. It requires a quite complex amplitude measuring instrument to accurately measure its amplitude. Because most users know too much about ultrasonic knowledge, coupled with the misleading of some salespersons, it gives consumers a wrong understanding.

The amount of electric energy consumed does not reflect the size of the output excess power. For example, the low longitudinal energy produced and the high consumed current can only indicate the low efficiency of the equipment and the high useless power.

Misunderstanding in the selection of ultrasonic welding machine: how much output power, oscillation frequency and amplitude range should be used should be considered according to the material of the workpiece, the area of the welding line, whether there are electronic components in the workpiece, whether it should be air tight and other factors. Mistakenly believe that the greater the power, the better. This is also a misunderstanding.

If you don't know much about ultrasound, consult the engineering and technical personnel of a regular ultrasonic manufacturer.
