Infrared welding, a non-contact assembly method, uses localized radiant heat from
contour-adopted, broadband metal foil emitters to melt the mating surfaces of
the parts to be assembled. This permits greater freedom in designing parts such
as complex curved joints and internal walls. The technique produces strong,
airtight welds with a solid, homogeneous bead and very good flash quality.
Compatible with most thermoplastics, infrared welding is particularly appropriate
for higher-temperatures processing, and is effective on semi-crystalline resins
such as polyethylene and polypropylene. In addition, the infrared heat source is
precisely controlled, important when dealing with heat-sensitive parts.
Infrared Welding
Laser Welding
Laser welding joins materials not easily welded by other thermal assembly
methods. This innovative technique is based on the STTIr™ (Simultaneous
Through Transmission Infrared) principle, where laser energy passes through
one plastic component and is absorbed by the second component. This
results in heating/melting of the interface, where controlled clamp force is
applied and the parts are joined.
The technique heats the entire weld surface simultaneously and has a rapid
cycle time, making it well suited to high-volume applications. Minimal flash and
no particulate produce parts with excellent cosmetic properties. Laser welding also permits preassembled parts to be
joined without affecting internal components, allowing for 3-D joint configurations and more flexible part design.
Hot plate welding utilizes a heated platen that directly contacts the mating surfaces of the
parts to be joined. This technique is cost-effective and compatible with most thermoplastics.
Greater latitude in parts design is possible, since the hot plate method can weld parts and
internal walls, and assemble thin-wall parts, complex geometries, large/multiple small parts
and parts with loose internal components.
