+/-0.2mmTypical tol.
A flashlight is primarily made by Deep Drawing. Deep drawing pushes a sheet blank into a die with a punch to form a seamless cup or box far deeper than the sheet is thick. Below is the full route to make a flashlight, 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 flashlight is made
The usual route, raw material to finished part. The amber step is where the flashlight gets its basic shape.
Material
Select the sheet grade and gauge for the flashlight.
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
Deep Drawing
Form the blank into the flashlight.
Tooling High (die set) Tolerance ±0.1 to 0.5mm Lead 10 to 20 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 flashlight 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 flashlight should cost
Cups, cans, enclosures at high volume; expensive multi-stage tooling, cheap per part once running.
PER-PART COST vs VOLUME
Per-part cost drops as volume spreads tooling and setup over more parts. The exact figures for a flashlight at your volume, in your currency, are in the dossier.

What does a flashlight cost?
It depends on size, tolerance and volume. As a rough ballpark it starts around $0.83 to 1.8 per part at 1,000 off and falls with quantity. The dossier gives should-cost at your exact volume and currency. A model estimate, not a quote.
What material is a flashlight made from?
Common choices are Deep-draw steel (DC04/DC06); Aluminium 1100/3003; Stainless 304 DDQ.
What is the main process for a flashlight?
Deep Drawing. Cans, sinks, pots, battery cans and pressure housings in volume.
