Ultrasonic welding at 40kHz is particularly
suited for smaller, precision plastic assembly applications
that require gentler action. The tooling of 40 kHz welders
is one-half the size of units operating at the more common
20 kHz frequency range. This results in a lower amplitute
of horn vibration and consequently less stress on the parts
being assembled.
The gentler action of 40 kHz ultrasonic welding
is fast, precise and virtually inaudible. 40 kHz welders and
componentsare smaller in size and are more readily accomodated
where space is a premium in automated assembly systems.
Typical assembly applications using 40 kHz ultrasonic
welders include microelectric components, printed circuit
boards, high-precision assemblies such as intricate medical
devices, and plastic parts in which class “A”
surface marking is undesirable.
40 kHz is also well suited for ultrasonic staking
or riveting, where the controlled flow of the molten plastic
is used to captureor retain another component, usually of
a dissimilar material.
All of PAS’s 40 kHz ultrasonic welding
equipment can be configured to meet the particular requirements
of a wide rangeof applications.
*For extremely high presicion, close tolerance
depth of weld applications, PAS’s MP Welder with stepper
motor drive and SSE power supply is recommended. to find out
more about the SMP Welder, call to request a brochure.
