Environmental requirements and the trend of lightweight make plastic more and more alternative industrial products in the metal part, and plastic laser welding relative to other welding technology, has more advantages:
Non-contact welding, no physical contact with the workpiece to be welded, no chemical reaction of the thermoplastic, operation in an industrial environment, suitable for medical and food industries requiring hygiene and safety. Medical industry is mainly used for injection systems, medical electronic equipment, a variety of artificial implants and stoma products.
Laser beam shape and size can be controlled, so as to control the size of heat-affected zone and joint area, high flexibility and good flexibility. Not limited to the size and shape of the parts to be welded, to achieve two-dimensional or even three-dimensional welding, to provide a basis for diversified custom parts production.
Welding speed, high weld strength, no flash, no residue, to ensure a good appearance of the welding area. Relevant data show that for ordinary passenger cars, the weight of non-metallic materials accounts for about 1/3, some of the larger proportion of models, plastic is one of the four non-metallic automotive materials. High-end car bumpers using plastic laser welding can achieve the best of both worlds. Other such as automotive filters, gas-liquid separator, car dashboard shell, electronic door openers, gearbox and other laser welding can play a good effect.
Precise and firm, airtight, watertight, can greatly reduce thermal stress and vibration stress, the most suitable for precision electronic components and vulnerable components.
