In the ultrasonic welding process, there are often scars, indentations, fractures or cracks on the surface of the product. At this stage, the ultrasonic plastic welding process has been applied to all walks of life due to its high efficiency, safety, and environmental protection. On the one hand, due to its unique material, when ultrasonic vibration acts on plastic parts, the surface of the product is prone to scalding, and 1m/ Thin plastic columns or holes within m are very easy to crack. These conditions are unavoidable in ultrasonic technology. On the other hand, the ultrasonic spot welding machine is used to repair some difficult welding effects. Therefore, the power output (number of segments), welding time, dynamic pressure and other cooperating factors must be considered to overcome this process defect.

How to deal with the indentation of the welding products of the ultrasonic plastic welding machine?

First, reduce the pressure, reduce the delay time, and reduce the welding time. Reference medium cover (such as PE bag). Mold surface treatment (hardened or chrome-plated). For products that are easy to crack or break, the mold should be cushioned, such as soft resin or covered with cork, etc. (this is to ensure that the welding strength is not affected). These are the problems that ultrasonic plastic welding machines need to solve. Now there are many equipment that use ultrasonic work, such as ultrasonic spot welding machines, spin welding machines, etc., which are all good products in welding machines.

For ultrasonic plastic welding machine, although there are certain advantages, we need to pay special attention to how to solve and avoid the scars on the surface of the product. The same is true for ultrasonic equipment parts. You must understand before using the ultrasonic plastic welding machine How it works.
