Ultrasonic Welding / Cutting / Sealing / Sewing / Weaving
Ultrasonic Blades / Knives are designed and produced for the use of phase angle controlled generators without frequency variation that involves geometrical restrictions related with high costs because:
– The height of the knife has to be tuned to the resonance frequency
– The sonotrode can only be built up to around 450mm length, without losing amplitude uniformity
– The sonotrode width at the top face has to be about 20mm to deliver a large enough contact area to the converter and to generate the amplitude amplification needed.
These Blades / Knives can be adjusted to particular applications, resulting in a simplified design for the manufacturers of cutting machines.
– Sandwiches, etc.
