What is the best plastic welding method?
Advantages of friction welding: high productivity, easy to realize automation and mechanization; when welding with a material, its joint performance is good, equipment is simple, and operation is convenient. Friction welding technology for a wide range of welding car axle, valve, airbag, turbocharger, gear, gear shaft, a constant velocity universal joint, front suspension etc..
Hot plate welding mainly used similar thermoplastic plastic welding, easy to control the same plastic melting temperature, the temperature control of the heating plate of the same relatively easy, simplify the difficulty of manufacturing the heating plate; for different types of plastic welding, the influence of temperature difference between the two plastic, must increase the difficulty of manufacturing and processing the heating plate, there will be insufficient strength.
The advantages of laser welding of plastics welding seam size precision, firmness, breathable and not Water Leakage closely connected parts of the surface, can rise; in the process of welding, resin degradation debris is produced less; compared with other welding methods, reduce product vibration and thermal stress can be a variety of plastic welding; it is good at products with complex shape; welding; welding to other methods is not easy to reach the area, easy to control, and has good adaptability;
The characteristics of ultrasonic welding, heating concentrated only in the welding part, solid weld appearance, regardless of the polarity of the size of plastic, plastic film almost all melting can be used with ultrasonic welding, especially suitable for welding of thin film materials with high rigid.
It must be welding with ultrasonic wave! Because he doesn't need other additives, and the efficiency and welding effects are not artificial. Unless you're a big plastic product.
