Introduction to multi-domain application of plastic laser welding
In recent years, plastic laser welding, as a new type of plastic connection, has many advantages such as high welding strength, good air tightness, strong flexibility and so on compared with the traditional plastic connection, and with the continuous development of technology and market, it is widely used in automobile, new energy, medical treatment, consumer electronics, food and other industries, therefore, the application field of plastic laser welding has a good application prospect for the huge plastic demand market.
Application in the field of auto parts with the society's higher and higher requirements for energy conservation, emission reduction and safety of automobiles, auto manufacturers are looking for lightweight manufacturing technology of automobiles and changing the packaging technology of traditional parts.
Plastic laser welding, a new connection process, has better strength, tightness, appearance, speed, stability and other advantages than ultrasonic and hot plate welding in the manufacture of some auto parts, as a high-end and cost-effective application technology, it is being popularized and applied at a high speed in the field of automobile manufacturing.
For example, the plastic laser welding machine with quasi-synchronous welding method in auto parts is applied to the welding of various combined valve bodies, the welding of valve bodies such as one-way valves and the welding of automobile instrument panels;
The plastic laser welding machine with sequential contour welding is used to weld various fuel pipelines and plastic joints, as well as high-end car bumpers, car welcome lights, Eddy current fans, car rear taillights, oil and gas separators, etc.
Application in automotive electronics some accessories related to automotive electronics have also changed from traditional glue filling and packaging to plastic laser welding: In the past, some automotive sensors were mostly packaged by glue filling, high cost, large weight, poor product appearance, etc.
The application of plastic laser welding to the customer site can greatly improve the product cost, light weight and appearance of the customer's products.
With the popularity of plastic laser welding, now most sensors have begun to use plastic laser welding package: such as car 360 camera, car radar, automatic door lock, electronic parking controller, head-up display, etc, using plastic laser welding can obtain high product quality and economy.
Application in medical devices due to the continuous improvement of the medical level in modern society, the requirements for medical devices are constantly improving, prompting new technologies to be applied to the production of medical devices.
Laser Plastic welding is a non-contact welding method, which will not produce vibration, noise and dust during the welding process. It is an extremely clean precision welding method, it is very suitable for precision welding of medical plastic products.
The medical microfluidic chip welded by mask welding can realize the advantages of accurate control of weld width, excellent air tightness and zero pollution to products.
The remote controller with sequential contour welding has extremely high welding air tightness and can easily cope with frequent cleaning and disinfection in medical places to ensure that the electronic components inside are not affected.
There are also sealed welding of devices with high cleanliness requirements, such as medical hose connection, blood analyzer, hearing aid, liquid filter tank, etc. , which are all used in plastic laser welding.
Application in consumer electronics plastic laser welding is applied to the welding of consumer electronics, such as the welding of watch watchband and VR glasses by plastic laser welding, can achieve beautiful appearance, high weld strength and other characteristics.
At present, some enterprises 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 it is in academic theory. The research in practical application field is relatively less than that in foreign countries.
If from the aspect of Enterprise, the laser can be regarded as the first batch of domestic large laser equipment manufacturers entering the field of plastic laser welding. Welcome to call information. . . . . .
