WebWelding of transparent polymers is possible using the intrinsic absorption of laser light emitted by Futonics laser systems. This patented technology offers high precision and control of the process. Various thermoplastic materials can be used with this method without the need for additives, leading to a more efficient overall process. WebLaser plastic welding, also often referred to as through-transmission welding, is a process of bonding plastic using focused laser radiation. The process is very much different than traditional metal welding. The concept involves passing a focused laser beam through an upper, laser transmissive part to the interface of the two parts to be ...
