Production Process
From brass disc to finished case: a six-stage production flow based on deep drawing.
ProcessDeep Drawing
Deep Drawing
Production Flow
Case production begins with a disc blanked from brass strip being deep drawn in progressive presses. Because each drawing step work-hardens the material, controlled annealing is applied between stages. The final stages cover head pressing, primer pocket machining, mouth trimming and dimensional calibration.
01
Blanking & Cupping
Blanking the disc from brass strip and forming the first cup.
02
Deep Drawing
Wall thickness is reduced in progressive drawing presses to reach the case body length.
03
Interstage Annealing
Annealing in a controlled atmosphere removes work hardening and makes the material formable again.
04
Head & Primer Pocket
Case head pressing, primer pocket and flash hole machining, extractor groove cutting.
05
Calibration & Trimming
Mouth trimming, length calibration and finalising the diameter tolerances.
06
Washing & Quality Control
Surface cleaning, polishing, sample-based dimensional and visual quality control, packaging.
Quality Control
Measurement at Every Stage
Sample-based dimensional and visual inspection is applied at every stage of the production line. Case length, head and mouth diameters, wall thickness and primer pocket dimensions are verified against the tolerances stated in the customer technical drawing.
- Stage-based sample measurement and record keeping
- Surface quality and burr inspection
- Dimensional tolerance verification
- Final visual inspection and sorting before packaging
