High Frequency Ultrasonic Sewing Machine Low Noise And Seamless

High frequency ultrasonic sewing machine low noise and seamless

Description 

The “cold” ultrasonic sealing technology also eliminates the need to clean hot sealing jaws. By reducing the issue of film sticking to the heated jaws, ultrasonic technology ensures that there is less material residue after sealing and fewer defective packages, all of which can help to reduce equipment downtime. As a result, manufacturers can see significantly increased operating times and a reduction in waste material.

Ultrasonic sealing

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 and include radii or small plateaus. 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.

Basics Ultrasonic sealing

Ultrasonic sealing is particularly well suited for:

Thermoplastic films (pouches and bags) Tubes, trays, and cups

Tubes, trays, and cups

Cardboard packaging with thermoplastic coating

Valves and vents on films / filter materials

Screw caps on coated cardboard packaging / films

Function

Raw material - Bag mouth fold - thermal bonding - side fold - bottom sealing - loop handle fix - thermal bonding - edge cut - bag cut - collection

Applications

Usually used in clothing industry is the ultrasonic lace machine, which is mainly used in cutting and welding cloth. Owing to its transmit horn is a plane, so it only can turn its own geometric center and cant turn the same direction with the cloth. Which make the sewed point of the cloth is unevenness. The transmit horn of Seamless sewing part is a circumference horn, and can turn around. For the cloth, it is jointing with the cloth and working at the same time. The ultrasonic seamless sewing part advance ultrasonic lace machine and its market prospects are very bright.
