Is the front bumper of the car solderable?
The front bumper of a car is a plastic weldable plastic. The welding method uses a heating method to simultaneously melt the contact faces of two plastic parts so that they are combined into a unitary connection method.
It can be welded or not used when welding. When using the electrode, the end of the welded end should be made into a shape (such as U-shaped, X-shaped, etc.), the molten metal of the electrode is filled in the seam, and the two parts are welded. Continuously integrated; when the electrode is not used, the welding surface is heated and melted, and then vertical pressure is applied to the surface to be welded until it is tightly integrated.
Plastic welding, hot plate machine, and rotary melting machine can be divided into softening by external heating source, softening by mechanical movement, and softening by electromagnetic action according to the different heating and softening methods used.
The front bumper of the car is plastic welded.
After the plastic welding is completed, it is very strong. However, to weld the inside of the bumper, the outer surface cannot be welded, because the plastic welding rod cannot be polished after the welding is completed.
Plastic welding, hot plate machine, and rotary melting machine can be divided into softening by external heating source, softening by mechanical movement, and softening by electromagnetic action according to the different heating and softening methods used. For car companies, the most direct effect is to save manufacturing costs. In addition, the plastic bumper can also protect pedestrians. At the beginning of the car, the speed of the vehicle is not fast. The general speed is 30-40 km/h, so it happens between the car and the pedestrian. The probability of an accident is also very low. But now with the continuous improvement of people's quality of life, the number of cars has increased, causing a significant increase in the probability of accidents involving vehicles and pedestrians. Pedestrians who are disadvantaged groups are often the most direct victims of accidents with cars. Therefore, in the current vehicle design, the protection of pedestrians has been raised to a high position. The appearance of plastic bumpers, the protection of pedestrians is quite obvious (provided that at a certain speed).
