+/-0.3mmTypical tol.
A tank end is primarily made by Metal Spinning. Metal spinning forms a rotating disc over a mandrel with a roller or tool, flowing the metal into an axially symmetric shape. Below is the full route to make a tank end, 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 tank end is made
The usual route, raw material to finished part. The amber step is where the tank end gets its basic shape.
Material
Select the sheet grade and gauge for the tank end.
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
Metal Spinning
Form the blank into the tank end.
Tooling Low (mandrel) Tolerance ±0.1 to 0.5mm Lead 1 to 4 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 tank end 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.

Axisymmetric parts (cones, dishes, nozzles); low tooling, great for low-to-mid volume round shells.
PER-PART COST vs VOLUME
Per-part cost drops as volume spreads tooling and setup over more parts. The exact figures for a tank end at your volume, in your currency, are in the dossier.

What does a tank end cost?
It depends on size, tolerance and volume. As a rough ballpark it starts around $97 to 275 per part at 1 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 tank end made from?
Common choices are Aluminium 1100/3003; Stainless 304; Copper/brass.
What is the main process for a tank end?
Metal Spinning. Cones, domes, bells and dished heads at low to medium volume with low tooling cost.
