Application prospects in the field of plastic laser welding

In recent years, plastic laser welding, as a new type of plastic connection method, has many advantages such as high welding strength, good air tightness, and strong flexibility compared with the traditional plastic connection method. It is widely used in automobile, new energy, medical, consumer electronics, food and other industries, so the plastic laser welding application field has a good application prospect for the huge plastic demand market.

1Application in the field of auto parts

With the society's higher and higher requirements for energy saving, emission reduction and safety of automobiles, automobile manufacturers are seeking lightweight manufacturing processes for automobiles and changing traditional parts packaging processes. Plastic laser welding, an emerging connection process, has the advantages of better strength, sealing, appearance, speed, and stability than ultrasonic and hot plate welding in the manufacture of some auto parts. Cost-effective application technology is gaining rapid popularization in the field of automobile manufacturing.

For example, the plastic laser welding machine using quasi-synchronous welding in auto parts is used in the welding of various combined valve bodies, the welding of valve bodies such as check valves, and the welding of automobile instrument panels; the plastic laser welding machine using sequential contour welding is used for welding. Various fuel lines and plastic joints, as well as high-end car bumpers, automobile welcome lights welding, eddy current fans, automobile rear tail lights, welding of oil and gas separators, etc.

2Application in automotive electronics

Some automotive electronics-related accessories have also been replaced by plastic laser welding from the traditional method of potting and packaging. In the past, most automotive sensors were packaged by potting, which was expensive, heavy, and poor in appearance. Applying the plastic laser welding method to the customer's site can greatly improve the product cost, light weight and appearance of the customer's products. With the popularity of plastic laser welding, most sensors have begun to use plastic laser welding packaging: such as automotive 360 cameras, automotive radar, automatic door locks, electronic parking controllers, head-up displays, etc., using plastic laser welding, all High product quality and economy can be obtained.

3Application in medical devices

Due to the continuous improvement of the medical level in modern society, the requirements for medical devices are constantly increasing, which promotes the application of new technologies to the production of medical devices. Laser plastic welding is a non-contact welding method, which does not generate vibration, noise and dust during the welding process. It is an extremely clean precision welding method and is very suitable for precision welding of medical plastic products.

The medical microfluidic chip welded by mask welding can achieve the advantages of precise control of the weld width, excellent air tightness and zero pollution to the product. The remote control using sequential contour welding has extremely high welding air tightness, which can easily cope with frequent cleaning and disinfection in medical places and ensure that the electronic components inside are not affected. There are also plastic laser welding for sealing and welding of devices with high cleanliness requirements, such as medical hose connections, blood analyzers, hearing aids, and liquid filter tanks.

4Application in Consumer Electronics

Plastic laser welding is applied to the welding of consumer electronics, such as the welding of watch straps and the packaging of VR glasses by plastic laser welding, which can achieve the characteristics of beautiful appearance and high weld strength.

Some companies have applied plastic laser welding to battery packaging and welding. With the development of laser technology and material technology, the technology of plastic laser welding will become more and more mature, and the application field will become more and more extensive.

The domestic research on plastic laser welding technology is relatively late, and most of the research is in academic theory, and the research in the field of practical application is relatively small compared with foreign countries. From the perspective of enterprises, Botel Laser is also one of the first large-scale laser equipment manufacturers to enter the field of plastic laser welding in China.
