The main causes of gaps include warpage and shrinkage of the molded product. The laser light is turned into heat energy as.

Welding of plastics presented by. Are you interested in any one of the topics. Download the seminar report for laser beam welding. Leading the potomac ppt effort in laser welding senior technical researcher natalia christensen has recently developed a new process to laser weld clear plastics that are between 50 and 200 microns thick.

The concept involves passing a focused laser beam through an upper laser transmissive part to the interface of the two parts to be joined. Higher joining quality minimal resulting flash or particulates higher quality controls less stress to the component and can weld complex and intricate shapes. The results are shown in figs. Although there are many methods for joining thermoplastics laser plastic welding has a few clear advantages.
