Laser plastic welding, also often referred to as through-transmission welding, is a process of bonding plastic using focused laser radiation. The concept involves passing a focused laser beam through an upper layer of a laser transmissive material to the interface of the two parts to be joined. The laser light is turned into heat energy as it is absorbed by the lower joining part. The heat created at the interface creates a molten weld seam and the two plastics are fused together. This process relies on four main factors: a laser transmissive layer, a laser absorbing layer, plastics material compatibility and good contact with no gap between the parts.
PW 2000 series laser plastic welding system can easily handle complex three-dimensional designs with a great economic advantage including, low TCO (total cost of ownership), short cycle times and high flexibility. Use of the PW 2000 series significantly reduces engineering and assembly time delivering higher margins and profits to the users. It comes with a solid state diode laser, high precision delivery optics, clamping mechanism, XYZR-stages and welding software for ease of use.
