Time-Saving Ultrasonic Ultrasonic Sealer Machine For PVC / PET Barrier Foils
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.
