Ultrasonic welding process: 

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 15.000 (15 Khz) 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.

 

 

 

Advantages of plastic file folder making 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.

Plastic file folder making machine: samples

 

 

One of the key factors to successful ultrasonic welding is good component design, in particular the shape of the surfaces to be joined ie the joint design. There are a variety of joint designs possible, each with specific features and advantages. The choice of design depends on the following factors:

1. Type of thermoplastic

2. Part geometry

3. Weld requirements

4. Aesthetics

One of the basic requirements of any joint design for ultrasonic welding is a small, uniform initial contact area. This can be achieved using a projection joint or a shear joint. plastic file folder making machine
