How to solve the problem of indentation when ultrasonic plastic welder welding

There are more and more types of ultrasonic plastic welding machine on the market now. In the ultrasonic welding operation, it is common for the product surface to produce scars, indentation, fracture or crack at the joint. So the use of ultrasonic plastic welding machine to work also will be more and more, because of its unique qualitative material, so ultrasound hair up for plastic products, product surface is prone to burn, and less than 1 m/m thick meat thin plastic column or hole, also easy to produce fracture phenomenon, this is ultrasound homework precedent phenomenon is inevitable. On the other hand, the Ultrasonic spot welder is used to repair some difficult welding effects. At this time, power output (number of segments), welding time, dynamic pressure and other matching factors must be considered to overcome this lack of operation.

First, reduce the pressure, reduce the delay time, and reduce the weld time. Reference media cover (such as PE bag). Surface finish of die fixture (hardened or chrome plated). For products that are easily cracked or broken, the fixture should be made of cushioning, such as soft resin or covered cork, etc. (this shall not affect the welding strength). These are the problems that need to be solved by ultrasonic plastic welding machine. There are many existing equipment that use ultrasonic work, such as ultrasonic spot welding machine, rotary welding machine, etc., which are good products in welding machine.

Therefore, for ultrasonic plastic welding machine, although there are certain advantages, but also need us to pay attention to is how to solve the surface of the product scars, how to avoid, for ultrasonic equipment parts is also the case, ultrasonic spot welding machine before use also want to understand its working principle to use.
