Clear polymer materials can be successfully bonded with a new process that combines simultaneous through-transmission infrared laser welding with precision ultrasonic spray deposition technology
Laser welding of plastic parts creates precise, high-quality, particulate-free joints for medical devices, consumer products and other assemblies. However, for the process to work, the laser light must pass through the top part to be absorbed by the bottom part. Welding a clear plastic part to another clear plastic part was not possible.
Now, Emerson has teamed with Sono-Tek Corp. to develop a new laser welding process that can do just that. Laser welds can be successfully created on a wide range of clear polymer materials using a process that combines Branson simultaneous through-transmission infrared laser welding technology from Emerson and precision ultrasonic spray deposition technology from Sono-Tek.
