Various situations of ultrasonic welding method for acrylic (PMMA)

There are many kinds of welding methods for PMMA, including ultrasonic welding and hot plate welding. What is the welding effect under different conditions? The test results of Lingke ultrasonic plastic welding research laboratory are as follows:

Ultrasonic welding:

Close up - very good welding

Long distance - very good welding (welding line is recommended on the welding surface)

Embedded connection - very good welding

Riveting - good welding

Spot welding - good welding

Hot plate welding:

Low temperature contact - good welding

Contact with high temperature - welding is very good

No contact - welding is acceptable
