A die block is primarily made by Open-die Forging. Open-die forging hammers or presses hot metal between flat or simple dies, shaping it by repeated blows while the smith manipulates the workpiece. Below is the full route to make a die block, 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 die block is made
The usual route, raw material to finished part. The amber step is where the die block gets its basic shape.
Material
Cut billet or bar stock to size for the die block.
Heating
Heat the billet to forging temperature so the metal flows.
Open-die Forging
Force the metal to shape between the dies: the grain follows the form and gives the die block its strength.
Tooling Low Tolerance ±1 to 6mm Lead 2 to 6 weeks
Trimming
Trim the flash and pierce any webs the dies leave behind.
Heat treatment
Normalise, quench and temper to the final mechanical properties.
Tooling n/a Tolerance can distort Lead days
Machining
Machine the bearing surfaces, threads and precise features to tolerance.
Tooling None Tolerance ±0.125mm, to ±0.025mm Lead 1 to 10 days
Inspection
Dimensional check plus crack detection on safety-critical parts.

Large, strong shafts/rings/blanks at low volume; shape is rough so plan generous machining stock.
PER-PART COST vs VOLUME
Per-part cost drops as volume spreads tooling and setup over more parts. The exact figures for a die block at your volume, in your currency, are in the dossier.

What does a die block cost?
It depends on size, tolerance and volume. As a rough ballpark it starts around $2165 to 3675 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 die block made from?
Common choices are Carbon/alloy steel (4140/4340); Stainless 304/316; Titanium.
What is the main process for a die block?
Open-die Forging. Large, simple, high-integrity shapes like shafts and rings where grain flow and strength matter.
