Automotive consoles have been assembled in many different ways. The use of Ultrasonics, Heat Staking, Vibration and Hot plate welders have been used to assemble a large portion of these consoles.

Instrument clusters have long been vibration welded. The clear acrylic is welded to the ABS mask. No marking occurs to this soft lens. Today there are lots of new trim rings (typically chrome plated) that are ultrasonically staked to the IP components.

Principle:

Definition of ultrasonic auto plastic welding: Ultrasonic welding is a high-tech technology of sintered plastic products. The use of this technology can replace past production of flux, adhesives, buckles or other mechanical fixation, thereby improving the production efficiency and reduce costs.The principle of ultrasonic welding is through the ultrasonic generator to convert high-frequency electrical energy into higher frequency mechanical movement, then mechanical movement through a set of amplitude can be changed to the transmission device to the welding head. The welding head transmits the received vibration energy to the joint portion of the workpiece to be welded, in which the vibration energy is converted into heat energy by friction and the plastic is melted. Ultrasonic not only can be used to weld hard thermoplastics, but also can process fabrics and films.

Condition of Ultrasonic Welding:

Ultrasonic automotive plastics as the condition of ultrasonic welding, the most important is the time to apply welding energy (vibration, welding time) length and pressure, of course, other conditions are also very important. Welding temperature ultrasonic welding material viscosity flow temperature. Otherwise the material will not melt.

The welding time varies depending on the material and the shape of the product. The welding time of some molded articles is only 0.2 seconds. Over time will cause excessive welding and produce a lot of flash and bubble, resulting in poor airtight, must pay attention. Cooling (holding) time For crystalline plastic, if the temperature below the melting point, the connection will be solidified, usually the pressure time is maintained between 0.1-0.2 seconds. AMMA plastic).
Ultrasonic implants: the nut screws or other metal into plastic work piece. Ultrasonic energy through the ultrasound machine will be transmitted to the metal. The high-speed vibration and heat, the pressure in the ultrasound machine to make metal objects embedded directly into the plastic inside.
Ultrasonic riveting: the nature of metal and plastic or two different plastic bonding together, can make use of ultrasonic riveting machine, so that the weldment hard brittle, beautiful, strong.
Ultrasonic welding: the use of ultrasound machine small welding head, the two pieces of plastic products into multi-point welding, or welding the first row of teeth on a direct pressure on the two plastic work piece, so as to achieve the effect of ultrasonic welding.

Applications In Automobile:

Ultrasonic Spot Welding is mainly used in automotive interior parts. Ultrasonic spot welding in sound-proof cotton of engine cover, trunk and wheel casing, and hallstand felt. Ultrasonic Riveting Welding can be used in automobile air-conditioning outlet welding, car rear view mirror, car door handles, hand car door and so on.

Automotive plastic parts are mostly welded in non-standard ultrasonic welding equipment, long multi-station design, with PCL program control and LCD operation, large automotive complex workpiece welding, including different directions of the welding surface, in multiple locations.
