Ultrasonics Assemble Automotive Sensors & Switches
The flexibility and reliability of
ultrasonic welding has seen the process being adopted for a wide range of
applications within the automotive industry to produce a variety of different
component parts and sub assemblies.
The latest suite of ultrasonic welding
systems from Telsonic UK draw on the precision characteristics of the process to
produce a series of exterior and interior components, including sensor housings
and switch bezels, for a number of current JLR models.
When assembling interior trim components it
is essential that the high quality of the “A” surface is maintained at all
times. This of course requires attention to detail when considering materials
and finishes for the component fixtures to maintain “A” surface integrity.
Equally important however is the selection of the joining technology to be used
to ensure that the welding process itself does not distort, discolour or
otherwise damage these critical surfaces and finishes.
Ultrasonic welding offers precise and
repeatable control of the joining process and these characteristics were
instrumental in the selection of the technology to produce complete car sets of
interior window control housing bezels for the X760 Jaguar. Each bezel
comprises of a chrome surround and a painted facia which has the apertures for
the window switches. These two individual parts are joined with six (passenger
side) or nine (drivers master unit) staking tabs depending upon variant.
