4.  Point-of-Cast Identification Methods

5. SAND MOLD CASTING OF DATA MATRIX
 Pre-Encoded high temperature stencils are
manufactured to the size that will survive repeated
overhaul processes during post manufacturing
processes
Pre-Encoded stencil is placed on the drag side of the casting
Using the head pressure to keep the stencil in place during poor
Stencil materials is made up of clay
binders and with stands 3000 F
 Stencils can be used
when pouring any type of
metal. Steel Casting,Brass
 Sand casted
valves

6. CASTING DATA MATRIX USING PERMANENT MOLD TOOLING
 Pre-encoded clay binder stencil
 Stencils are placed into the mold with a activated
adhesive that gets tacky at 200 F
Stencil falls out during shake
out.
Revealing a unique Barcode
Pouring the molded part

7. INVESTMENT CASTING
 Pre-encoded stencil is pressed into Freedom
wax. Making a duplicate of the Data matrix
barcode
Duplicate of barcode on the Freedom Wax ready to be
Applied to the wax mold
Pre-encoded stencil is applied to wax mold
And applied to tree . Trees are dipped in a
Ceramic slurry
Investment casted barcode on the side of a runner
In a foundry in Fort Worth

8. Thermal Spray Direct Part Marking
 Electric Arc Spray
 High Velocity Oxygen Fuel (HVOF)

9. Data Matrix Marks By Electric Arc Process
Electric Arch Diagram
Thermal Spray Gun
Uses Shop air and 3 phase Basic Principals of Thermal Spray
Power.
Sprayed Substrate With
 Electric Arch Process
Substrate is grit blasted and stencil is rolled down
Stencil will turn blue when rolled down completely
.
Electric Arch
Spray De-masked Electric Arc Mark

10. Using HVOF To Create Data Matrix Symbols
 The stencil is applied to the part after grit blast.
The part and stencil are shot using The HVOF or
plasma process.
 Part Is Shot using a
Plasma or a HVOF
Process
 Pseudo Alloy was applied to
line Pipe. Pre grit blast before
) FBE was applied. Mark went
through 3 shot blasts
Stencil was sprayed and went through mill

11. Epoxy Direct Part Mark
 Pre-encoded Teflon stencil with Silicon adhesive
 Teflon Stencil Being rolled down
White epoxy being Silk screened through
stencil
Stencil being de-masked , no residue

12. Responsibilities
