The ultrasonic dot-line sealer L-QP-01 welds materials in a dot-line pattern without using adhesives or tapes.
It is used by rotating and sliding the gear tip on the handpiece.
Sealing can be done while drawing dot lines, and can be used for sheet materials such as non-woven fabrics.


 

We conducted welding tests of various plastics with Ultrasonic dot-line sealer L-QP-01.
In general, ultrasonic sealers are able to weld thermoplastic resins.
However, Ultrasonic dot-line sealer L-QP-01 can weld some materials easily and some materials hardly due to the shape of the welding tip.
We have tested various materials and thicknesses of plastic. We hope this information will help you when you consider the purchase of this product.

Ultrasonic dot-line sealer L-QP-01 is very useful when you want to fasten small parts that are difficult to adhere with a normal sealer or when you want to fix them without using adhesives.
However, the seal quality will change depending on the type and thickness of the material.

We offer a seal test service. Please send us a sample of the material you want to seal.
We will report the sealing results and return the sealed sample to you.
Please contact us.
