A Brazing or
soldering Preform is any solid shape of filler that can be placed
in an assembly prior to the heating cycle.
The
continual upgrade in the automation of metal joining processes
coupled with the evolution of new brazing alloys has stimulated
new growth in perform design. We can manufactures custom stamped
performs from over 1,000 tools already on our shelves. Chances are
we have existing tooling to meet your specific requirement.
However, if we need to develop new tooling, our precision machine
shop keeps cost and lead times to a minimum.
Preforms
are available in the following formats:
Types
of Preforms
Preform
Capabilities
A variety
of styles based on the needs of the application. Examples
include, Lap, Butt End, Gap, Multi-Turn, Segment/Arc, or
Edgewounds.
Ring Coiling Wire
(available in all alloys): .005” to .187” diameter.
Ring Diameters: .030”
I.D. to 13” O.D.
Blanked
Washers, Discs, Shims, Special Shapes - fabricated from
brazing alloy strip and used where joint clearances or
joint design prevent the use of wire forms. Available in
.001” to .100” thicknesses.
The most
economical preform to manufacture. Slugs can be made from
any brazing wire and cut to required length. Available in
.005” to .750” diameter.
Brazing wire can be formed
into an infinite variety of configurations to meet
customer application requirements.
Primarily
spheres and disc shapes. Used in joints of limited access
that require a large volume of alloy.
Brazing preforms improve quality while lowering production costs
by:
Eliminating
costly hand-fed operations,
Accurately
controlling brazing alloy volume for fewer incomplete joints,
Providing
access to automated brazing and soldering systems, and
Demonstrating
uniform wetting and smooth joint appearance.
