Because of its unique advantages, laser welding plastic technology is becoming a hot spot in the field of laser welding, and has been widely concerned by the industry, it will replace the traditional plastic welding method. This issue of Ouwei Xiaobian will give you a brief introduction to Ouwei laser plastic welding technology what are the main characteristics?
The main characteristics of EVLaser plastic welding technology
The basic principle of laser welding plastics:The two plastics are clamped together at low pressure. The laser passes through one product and is absorbed by another. Products that absorb laser energy convert light energy into heat and melt on the contact surface of the plastic, forming a welding zone. Most natural plastics and many colored translucent plastics can be laser welded, such as polyvinyl chloride (PVC), polystyrene (PS), polystyrene (PP). The application of plastic laser welding in the automotive industry includes the laser welding of automotive taillights and the laser welding of automotive baffles.
The basic principle of laser welding plastics
The main methods of plastic laser welding are: contour welding, synchronous welding, quasi-synchronous welding and irradiation mask welding.
Plastic laser welding machine features
1. Solid welding;
2. No flash;
3. No vibration technology;
4. Reduce thermal damage and thermal deformation;
5. Power saving, maintenance free, environmental protection, high efficiency, no consumables;
6. High precision welding parts can be obtained;
7. Can produce air tightness or vacuum seal structure;
8. The welding equipment does not need to be in contact with the bonded plastic parts;
9. Resins of different compositions or colors can be bonded together;
10. High degree of automation, very convenient for complex plastic parts processing.
Advantages of plastic laser welding
At present, the most common welding technology in China is friction welding, ultrasonic welding and hot gas welding, etc. Compared with traditional plastic welding technology, plastic laser welding technology mainly has the following advantages:
(1) The heating and cooling speed is extremely fast, which greatly reduces the thermal stress and vibration stress of plastic products.
(2) Laser welding is simple to control, belongs to non-contact processing, strong adaptability, and has strong operability for complex structures or small weldparts.
(3) With the continuous upgrading of laser welding equipment, its cost is further reduced, and its performance is continuously improved, compared with other welding equipment, it has the advantages of easy maintenance, convenient operation, and support for long-term use.
(4) After laser welding, the weldment quality is good, the weld is firm, precise and stable, and the welding process does not produce pollution, which is a very environmentally friendly welding technology.
(5) Laser welding, strong applicability, can be welded under a variety of conditions and can ensure the quality of the weldment, such as in vacuum, air or a medium environment, but also through transparent plastic welding on the contact surface of the weldment.
Laser plastic welding technology can weld a wide variety of plastic parts:
Automotive field: fuel nozzle, shift frame, engine sensor, cab frame, hydraulic fuel tank, filter frame, headlight, taillight, auto door lock, car keyless access equipment and sensors.
Medical field: liquid storage tanks, liquid filtration equipment, hose connectors, ostomy bags, hearing AIDS, implants, microfluidic devices for analysis, etc.
Electronic field: electronic components, mice, mobile phones, connecting devices, microphones, etc.
Waterproof clothing: Laser welded textiles through laser stitching, solid and reliable seams, especially suitable for waterproof clothing and equipment with high air tightness requirements.
Packaging of industrial products: The packaging of some industrial products, the use of plastic film welding technology, can get a solid weld, beautiful appearance of plastic packaging.
These are the main characteristics of laser plastic welding technology introduced by Ouwei Xiaobian. More about the application of laser plastic welding technology, please pay attention to us, we will serve you wholeheartedly.
