designed to provide professionals in the automotive industry
robust, effective and controllable welding equipment and solutions.
Altrasonic plastic welding solutions are designed to help
automotive parts manufacturers to satisfy their customer’s
expectations. We work with you from concept to launch. Beginning
with designing your auto parts according to your criteria.
Continuing to provide low cost, lean manufacturing solutions and
working with you until you meet your customer’s requirements into
production.
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.
