Process of Ultrasonic Plastic Welding Machine

Step 1 - Parts in fixture

The two thermoplastic parts to be assembled are placed together, one on top of the

other, in a supportive nest called a fixture.

Step 2 - Horn contact

A titanium or aluminum component called a horn is brought into contact with the

upper plastic part.

Step 3 - Pressure applied

A controlled pressure is applied to the parts, clamping them together against the

fixture.

Step 4 - Weld time

The horn is vibrated vertically 20,000 (20 kHz) or 40,000 (40 kHz) times per second, at distances measured in thousandths of an inch (microns), for a predetermined amount of time called weld time. Through careful part design, this vibratory mechanical energy is directed to limited points of contact between the two parts. The mechanical vibrations are transmitted through the thermoplastic materials to the joint interface to create frictional heat. When the temperature at the joint interface reaches the melting point, plastic melts and flows, and the vibration is

stopped. This allows the melted plastic to begin cooling.

Step 5 - Hold time

The clamping force is maintained for a predetermined amount of time to allow the

parts to fuse as the melted plastic cools and solidifies. This is known as hold time.

(Note: Improved joint strength and hermeticity may be achieved by applying a

higher force during the hold time. This is accomplished using dual pressure.)

Step 6 - Horn retracts

Once the melted plastic has solidified, the clamping force is removed and the horn

is retracted. The two plastic parts are now joined as if molded together and are

removed from the fixture as one part.



Adsvantages of Ultrasonic plastic welding machine



Plastics assembly is a fast, clean, efficient, and repeatable process that consumes very little energy. No solvents, adhesives, mechanical fasteners, or other consumables are required, and finished assemblies are strong and clean.
