Cylinder Type Hand Welder Ultrasonic Assembly Spot Welding System 35kHz 1000W ABS PP
Dscription:
The ultrasonic waves vibrate 10's of thousands of times per-second.
This oscillation is transferred to a contact surface that is
directly in contact with the plastic parts. Since the boundary of
the welding area has a large acoustic impedance, it produces high
temperatures. Plastic is a pretty poor conductor of heat and can't
dissipate the heat before it changes the state of the plastic from
solid to liquid. With a bit of pressure applied, this makes the two
parts blend together as if they are a single piece of plastic. Once
the ultrasonic signal is stopped, the parts become solid again.
This is the magic that creates a weld between the two parts that is
clean and very strong. The weld will have a strength that is close
to that of the raw materials being formed together in an injection
molding process.

Advantage:
1. Ultrasonic is the fastest, most repeatable and economical
assembly method available to the industry today.
2. With ultrasonic, most thermoplastics can be assembled without
heat, mechanical fasteners, or hazardous consumables such as
adhesives or solvents.
3. Ultrasonic can join parts - small or large, simple or complex -
with lower reject rates than any other method.
4. Using ultrasonic, labor - both as a skill factor and as a time
factor - is significantly reduced. And since the equipment can
readily be automated, any non-technical operator can be trained in
minutes to produce high volume, high integrity assemblies.
Application:
Ultrasonic plastic welding is also utilized in the medical
industry, primarily because it doesn’t introduce contaminants.
Items such as anesthesia filters, blood filters, IV catheters,
dialysis tubes and face masks can be made using ultrasonic plastic
welding. Another important application in the medical field is the
construction of such textile wear as hospital gowns, surgery
garments, and transdermal patches, just to name a few. These items
can be sewn and sealed using ultrasonic plastic welding to avoid
and reduce the risk of infection.
Ultrasonic plastic welding is frequently used in the packaging
industry. Everyday items, ranging from butane lighters to food
containers, are created or packaged with ultrasonic plastic
welding. Ultrasonic plastic welding is also found in the packaging
of dangerous explosives, such as fireworks or dangerous chemicals.
These items can’t be subjected to high temperatures, yet must be
contained in an airtight container that can withstand stress and
high pressure.
The food industry relies on ultrasonic plastic welding because it’s
fast and sanitary while producing airtight seals. Milk and juice
containers are prime examples of products sealed with an ultrasonic
plastic welding machine. To complete the task, paper cartons are
coated with sheer layers of plastic that are then welded together.
