Punched Metal Components - Sheet Metal Fabrication

Punched Metal Components

Turret-punched parts with formed features, economical from a few hundred pieces upward.

Punching beats laser on volume and adds formed features in the same pass - louvres, countersinks, extruded holes. The tooling is quick to set up, so the crossover is a few hundred parts rather than thousands.

What drives the price of this part

Derived from the callouts on this page. Where a driver is not on the drawing, it is not on this list.

Tolerance
Hole tolerance at ±0.1 mm is the tightest callout this family carries. Tightening a callout is a process decision, not a machining decision: below the standard ±0.005 mm the work moves to grinding or jig boring, and the price moves with it.
Part size
Material thickness at 0.5–6.0 mm decides which machine the part lands on and how many setups it needs. Size is the driver buyers most often leave out of a first enquiry, and it is the one that changes the quote fastest.
Material
The first material listed, Stainless Steel 304 / 304L, rates 4/10 on our machinability scale at 201 HB. On this shop's scale a harder alloy means slower passes and more tool changes, and that is cycle time the quote has to carry.
Order size
Minimum order is 250 pieces, where setup and tooling are amortised across the batch and per-part cost settles around cycle time and material. Below that quantity the same part costs more per piece, not less.

See how cycle time is calculated in the machining time calculator and what else moves a price in the cost driver reference.

How these parts are inspected

Matched to the callouts above and the instruments actually on the floor.

  • Coordinate measuring machine (Zeiss CONTURA G2, two machines, GR&R 8.4% on the critical feature)
  • Dimensional report against the drawing, with a 100% check on critical features rather than a sample
  • Certificate of conformance and the mill certificate with every shipment
  • Bore gauges and an optical comparator for hole position and edge form

The full equipment list, with counts, is on the capability page; the inspection sequence is on quality and inspection.

Questions buyers ask

Punching or laser for 500 parts?
Punching, usually. The tool setup is an hour and the cycle is seconds per part; by 500 pieces the laser has spent more time cutting than the punch spent tooling.
Can you extrude a threaded hole instead of using a rivet nut?
Yes, if the wall is thick enough to form a thread - about 1.2 mm in steel. Below that the extrusion tears, and a rivet nut is the better answer.
