+/-0.05mmTypical tol.
A strap tie is primarily made by Stamping (Progressive Die). Stamping runs sheet metal through a press with progressive dies that blank, pierce, form and coin the part in successive stations at high speed. Below is the full route to make a strap tie, the materials it suits, the tolerances to expect and the main design points. The route is free, from the finder.
Step by step
How a strap tie is made
The usual route, raw material to finished part. The amber step is where the strap tie gets its basic shape.
Material
Select the sheet grade and gauge for the strap tie.
Blanking
Cut the flat blank, by laser for low volume or a blanking die at scale.
Tooling Low (laser) to high (die) Tolerance ±0.05 to 0.3mm Lead days to weeks
Stamping (Progressive Die)
Form the blank into the strap tie.
Tooling Very high Tolerance ±0.05 to 0.25mm Lead 12 to 24 weeks
Secondary features
Punch or drill the holes and cut-outs the part needs.
Tooling None Tolerance ±0.05 to 0.2mm Lead hours to days
Joining
Spot weld, fasten or bond into the assembly where the strap tie is more than one piece.
Tooling Medium Tolerance joint Lead immediate
Finish
Deburr the edges and powder coat or plate for protection and colour.
Tooling Low Tolerance adds 0.05 to 0.2mm Lead days
Inspection
Check formed dimensions, hole positions and flatness.

Cost
What a strap tie should cost
Terminals, brackets, clips at huge volume; the progressive die is everything, piece cost is tiny.
PER-PART COST vs VOLUME
Per-part cost drops as volume spreads tooling and setup over more parts. The exact figures for a strap tie at your volume, in your currency, are in the dossier.
