Frequently Asked Questions
What is plastic welding?
Thermoplastic “or plastic” welding is a process for
joining pieces of coating or laminated thermoplastic material using heat and
pressure. The surface of the material is heated to its meltpoint and pressed
together until it cools.
Do I need to be welding or seam sealing?
If you have the following requirements then you will
want to look further into welding. If a product needs to be (have) :
-
Waterproof or water resistant
-
Pressurized (positive or negative pressure)
-
Highly abrasion resistant at the seam
-
Resistant to thread rot
-
A new cool look!
Welding can also help reduce cost by:

What types of welding are there?
There are 4 basic categories of plastic welding that
are used for flexible products. There are other types but the one mentioned here
are the most widely used.
-
Hot Air
-
Hot Wedge
-
Radio Frequency
-
Ultra Sonic
Hot Air, Hot Wedge, Ultrasonic are usually
rotary
type welders which means it is a continuous process. The
material is moving through the machine while it is being welded.
Radio Frequency (RF) and Impulse welders are a
stamping type machine. The
material pieces are held in place (not moving) while they are being welded. See
“Dielectric Welding Vs. Rotary Welding”
for more information on Rotary Vs. Stamping.
