35kHz Or 20kHz Ultrasonic Sealing Machine Ultrasonic Solution
Various Quilting Patterns
Description:
With ultrasonic sealing, the heat required for melting is only generated inside the
thermoplastic sealing layer. For localized conversion of vibrations
to friction heat, the anvil or sonotrode profiles are mostly
linear. These profiles ensure focusing of the energy input and
therefore short sealing times between 100 and 200 milliseconds.
With ultrasonic sealing heat is generated at the inside of the
film, not by heat input from the outside as is the case with heat
sealing, for example. The tools (sonotrode and anvil) that come
into direct contact with the packaging material, remain cold during
the entire weld process. The support layer remains almost cold and
upon termination of energy input, the heat dissipates faster to the
outside due to the temperature difference between the support layer
and the sealing layer so that the hot-tack resistance is
significantly higher.

Application:
Apply to lace clothing, ribbon,trim,Filter, Lacing and
quilting,decoration products, handkerchief, tablecloth, curtain,
bedspread, pillowcase, quilt cover, tent, raincoat, disposable
operating coat and hat, disposable mask, non-woven fabric bags and
so on.
Principle:
Ultrasonic lace sewing machine used ultrasonic vibration and steel
moulds, the above processing will be finished together with
pressure.
Function:
Raw material - Bag mouth fold - thermal bonding - side fold -
bottom sealing - loop handle fix - thermal bonding - edge cut - bag
cut - collection
Advantages:
1. There’s no fog and spark in produce processing, won’t cause
damage to fabric edge,
and also can avoid deckle edge.
2. Chang of the ultrasonic cutting die is very easy, and the design
of themoulds can
also made according to customer’s requirement.
3. Without pre-heating, and continuous operation is possible.
4. Machines can be combined to one set of equipments in order to
sew large width
products once, for instance, guilt cover, gingham, etc.
5. The cutting moulds (cutting die) that be made of special alloy
steel which has been
treated with special heat treatment technology, so the moulds with
high wear resistance
and gains a longer service life.
