Plastic laser welding

Plastic laser welding is a non-contact welding technology.

Compared with other welding methods, it has the advantages of non-contact, air tight, water tight, fast welding speed, high precision, strong resistance, no flash, residual and vibration, minimum thermal stress, easy control, flexibility and adaptability.

Bonding is the key to the wide application of automotive plastics.

The level of plastic welding technology is one of the important symbols to measure the development level of automobile manufacturing technology and new materials.

Laser welding technology has been widely used in automobile industry for its advantages of economy, simplicity, rapidity, reliability and mass production.

The principle of laser welding is to use the heat generated by laser to weld the plastic surface, and then glue the thermoplastic sheet, film or molded parts together, so as to realize cutting, welding and waterproof.

Plastic laser welding is a very professional welding technology.

When high speed welding, precision welding and aseptic welding are required, the advantages of laser welding can be brought into full play.

This process was once affected by the price factor, but with the continuous decline of equipment price, it has a strong competitiveness in many application fields.

Laser welding of plastic parts of automobile fuel system.

With the release of the sixth automotive industry standard, the fuel system of a large number of injection molded parts needs laser welding, such as the most typical fuel injection nozzle, various nozzles and plastic joints, muffler, various combination valve bodies, check valves and other valve bodies.

Two kinds of materials are mainly used in plastic laser welding of various fuel system parts: Nylon plus glass fiber and polyoxymethylene.

These two materials have been used for a long time in various laser plastic welding applications in the automotive industry.

There is no problem of laser welding materials.

Laser welding EPB electronic parking system plastic parts mainly involve EPB electronic parking controller shell and EPB electronic parking mg u plastic shell.

The structure design of EPB controller and MGU shell adopts quasi synchronous welding structure.

The bottom is designed with welding bars.

The laser scans rapidly along the electrode.

After welding, the whole electrode is melted to form a welding bed.

The advantages of quasi synchronous plastic welding process are as follows: on the one hand, the deformation of plastic parts can be compensated by the fracture of welding rib; On the other hand, it can be used as one of the quality control standards to monitor the fracture of welded bars.

3. Plastic laser welding automobile instrument panel.

The traditional instrument panel is plastically welded by vibration friction.

High frequency vibration marking welding instrument panel surface.

Therefore, the vibration friction welding tongs need to be coated with soft materials to prevent scratching the instrument panel during welding.

Another small problem about vibration friction welding is welding slag, which is not conducive to cleaning.

For instrument panel welding, the biggest problem of vibration friction welding is a lot of glue overflow after welding, and the weld or welding area is very poor.

The conventional method is to hide the weld.

However, with the increasing sophistication of automotive interior design, the space left for plastic welding design is less and less.

The visual aspect of the indicator plate weld is completely exposed.

Therefore, looking for a novel and beautiful laser plastic welding process has become a real demand of people.
