Much faster than conventional adhesives or solvents.
Drying time is very quick.
The pieces do not need to remain in a fixture for long periods of time waiting for the joint to dry or cure.
The welding can easily be automated, making clean and precise joints.
The site of the weld is very clean and rarely requires any touch-up work.
The low thermal impact on the materials involved enables a greater number of materials to be welded together
Flexible and versatile with little tooling changeover or fixture modifications, consistent and repeatable, very rapid weld time confined to the bonding or joint area, can replace fasteners and adhesives.
It has 16 weld programs which include parameters like Trigger pressure, Weld pressure, Amplitude etc.
Part design –Ultrasonic Weld Joint
Energy director: Define a place to start the weld
Sonotrode contact: Allow the ultrasound to have a direct path to the joining area
Support: Allow the bottom weld-part to resist deformation
Melt encapsulation: Prevent the melt from leaving the joint
Centering: Ensure a consistent alignment
Volume and part travel: Allow the part to move freely and the melt to go somewhere
Prevent hard stop
Let the part sink into the melt during holding
The most commonly utilized joint designs that AMTEC recommends
Step Joint (chisel)
Tongue and Groove Joint
These designs all utilize the most important design rules. The use of each design is subject to the specific application and requirements of the weld.
