Leister (www.leisterlaser.com) has developed various laser welding concepts to offer solutions for every application. Leister Laser Plastic Welding offers laser systems for frequently used techniques to laser weld thermoplastics including contour welding, GLOBO welding, and mask welding. In contour welding, two pieces of plastic are clamped together and a laser beam is guided sequentially along a predetermined welding pattern. Our mask welding technique uses a chrome mask to protect areas that should remain untouched when a curtain of laser light is moved across the part -- fast and efficient! With GLOBO welding, a laser beam is focused at a point on the joining plane via an air bearing, freely rotating glass sphere which also serves as a mechanical clamping tool. This process allows welding 3D patterns or 2D patterns that are difficult or impossible to clamp.
