ACM provides a variety of value-added services, including Ultrasonic Welding,
to help complete your project. Ultrasonic Welding is used to bond two pieces of plastic together.
Ultrasonic welding of plastics has many advantages over other
plastic-joining processes, including:
Lower cost - eliminates the costs of consumables, produces
repeatable, error-free results
Higher speed - welding usually occurs in less than a second.
Cleaner process - no consumables required, less risk of
contamination
Greater
reliability - adaptable to clean-room environments as well as
high-volume production situations
Ultrasonic Welding: Applications & Uses
Ultrasonic
assembly is ideal for assembling all types
of medical products, such as:
Filters
Instruments
Fluid vials
Masks
Surgical garments
Ultrasonic welding has a wide variety of additional uses and applications, including:
Sealing containers and bags
Attaching plastic components
Inserting metal components into plastics
Corrugated containers - eliminates need for staples or adhesives
Plastic Tubes and pumps - will not contaminate contents
Ultrasonic Welding: Safe, Fast Process for High Volume Production
Ultrasonic welding is probably the most commonly used
thermoplastic welding process.
Very fast
(fractions to a few seconds)
Usually produces welds that
are relatively free of flash
Suitable for high volume production
Unlike most other methods of plastics joining, ultrasonic welding uses
no caustic chemicals and produces few fumes.
The only restriction on
welding plastics is that the parts must have relatively close melting
points, or else one will melt completely before the other begins to soften.
Ultrasonic Welding: A Brief Explanation
Ultrasonic welding uses the potential energy within the plastic
itself, converting it to heat and sound.
Parts are vibrated toward and away from each other
Continued motion heats and softens the plastics
Vibrations mix softened plastic surfaces together
Forms a physical as well as chemical bond if the plastics are selected correctly
A sonic horn oscillates vertically and
delivers the energy where it's needed by contacting the plastic
part at a variable distance from the projection point, depending on the
application
The part on the other side
of the joint area rests on an energy-dampening anvil, ensuring the sonic
energy remains in the weld zone
Tongue & groove joint design and location is very important in ultrasonic
welding
Interference, or shear types of joints, involve
welding a slightly larger part into a smaller one
Shear joint designs are commonly used for semi-crystalline polymers,
or when watertight seals or high joint strengths are needed
Rapid development of the ultrasonic welding machine has
occurred in the last ten years. Basic functions are now
computer-controlled for greater accuracy and reliability, such as:
Weld energy
Collapse
Trigger force
Pressure
