Why is laser welding an inevitable new choice for plastic welding?
发布时间:2018-03-08 11:27:35浏览次数: Article source : Editor's release time : 2018-03-08 11: 27: 35Views


At present, there are many methods for plastic welding including ultrasonic welding, hot plate welding, vibration friction welding, and laser welding. As a non-contact welding technology, compared with other welding methods, laser welding has the advantages of non-contact, air tightness, water leakage, fast and efficient, high accuracy, beautiful welding seams, unlimited product appearance, easy control, and strong adaptability. Will become the trend of plastic welding in the future.

[Industry application]

激光焊接塑料技术可用于制造很多汽车零部件,如 燃油喷嘴 、变档机架、发动机传感器、驾驶室机架、液压油箱、过滤架、前灯和尾灯等。 In the automotive industry: Laser-welded plastic technology can be used to make many automotive parts, such as fuel nozzles , shifting frames, engine sensors, cab frames, hydraulic fuel tanks, filter frames, headlights and taillights. Other automotive applications include the manufacture of intake manifolds and auxiliary water pumps. Automotive headlamps processed by laser welding technology use glass spheres that can focus the laser and also serve as a clamping tool.

Laser welding is a vibration-free technology, so it is particularly suitable for processing precision electronic components. The equipment manufactured by laser technology includes a mouse, a mobile phone, and a connecting device. Automotive electronics manufactured by laser technology include automatic door locks, keyless entry and exit devices, and sensors. The laser can also weld plastic films together. It moves along the edges of the film to form a packaging structure through bonding. The operation process can be completed very quickly.

[Major conclusions]

Laser welding plastic technology is a very specialized bonding technology. When high-speed welding is required and precision welding or aseptic welding is required, this can give the best advantage of laser welding. This technology was once constrained by price factors, but with the continuous decline in equipment prices, it has become more competitive than ultrasonic welding and hot plate welding in many applications. The main applications of laser welding technology are medical, automotive, electronics and packaging.

【Plastic laser welding equipment】

At present, domestic plastic laser welding equipment has just started, and most of them are in the exploration stage. The technology of laser plastic welding equipment pioneered by Wuhan Boliant is the first in the industry. At present, it has been maturely applied to customers in the automotive industry and the medical industry, and has been well received by customers.

[Advantages of laser plastic welding]

The advantages of laser welding applied to the welding of plastic parts include: precision welding, firmness and tightness, airtightness and water leakage, less resin degradation and less debris during welding, and the surface of the product can be tightly connected together around the weld. Laser welding does not have the advantages of residues, making it more suitable for medical products and electronic sensors controlled by the State Food and Drug Administration.
Easy to control, can weld workpieces with small size or complicated structure. Because the laser is convenient for computer software control, and the output of the fiber laser can flexibly reach all subtle parts of the part, laser welding can be used to weld areas that are not easily reached by other welding methods.
Compared with other welding methods, laser welding significantly reduces the vibration and thermal stress of the product. This means that the product or the internal components of the device age more slowly and can be applied to products that are easily damaged. Capable of welding many different materials.

As a non-contact, fast and beautiful welding method, laser welding will become the development trend of plastic welding in the future. Therefore, some domestic and foreign material manufacturers have begun to develop materials suitable for laser welding. High-quality laser welding has become an inevitable choice.
