High Strength 20Khz Ultrasonic Welding System for Femcare And
Hygiene Welding
Ultrasonic technology produces strong, repeatable seams and joints,
withstands sterilization processes, and eliminates the need for
solvents or glues, it not only solves medical nonwoven and device
manufacturing problems, but does so while reducing the risks and
sources of potential contamination.New opportunities for
ultrasonics in the nonwovens industry are everywhere, driven in the
short term as manufacturers learn more about the value and
versatility of this process, and in the longer term by changing
demographics. As the number of older citizens in the U.S. and many
western countries continues to grow as a share of total population,
the demand for medical, sanitary, consumer care, bedding, seating,
cleaning, and filtration products will only continue to grow. So
too will the need to produce these products efficiently, with
maximum cleanliness and minimum risk of contamination.
Ultrasonic offers the perfect solution to this growing need because
of the equipment’s’ unique ability to handle a broad scope of
nonwoven product manufacturing, including slitting, cutting,
embossing, quilting and bonding.
ultrasonics is a technology that has become more and more accepted
as time passes. Raw material suppliers understand the benefits of
ultrasonics and often construct their materials with bicomponent
fibers so the end user may join nonwovens with this technology,
thus eliminating the need for consumables such as adhesives, needle
and thread or mechanical crimping devices.
For joining complex injection molded thermoplastic parts,
ultrasonic welding equipment can be easily customized to fit the
exact specifications of the parts being welded. The parts are
sandwiched between a fixed shaped nest (anvil) and a sonotrode
(horn) connected to a transducer, and a ~20 kHz low-amplitude
acoustic vibration is emitted.When welding plastics, the interface
of the two parts is specially designed to concentrate the melting
process. One of the materials usually has a spiked or rounded
energy director which contacts the second plastic part. The
ultrasonic energy melts the point contact between the parts,
creating a joint. This process is a good automated alternative to
glue, screws or snap-fit designs. It is typically used with small
parts (e.g. cell phones, consumer electronics, disposable medical
tools, toys, etc.) but it can be used on parts as large as a small
automotive instrument cluster. Ultrasonics can also be used to weld
metals, but are typically limited to small welds of thin, malleable
metals, e.g. aluminum, copper, nickel. Ultrasonics would not be
used in welding the chassis of an automobile or in welding pieces
of a bicycle together, due to the power levels required.
