Press forming & deep drawing
Hydraulic presses stretch flat metal into seamless, hollow shapes, which are then trimmed to length.

Proqyur Precision
One partner. Blank to finished part.
One order can cover every step, with one team responsible for the finished part. Six capabilities across two plants. Fewer suppliers, fewer handovers, one point of contact.
CNC machining
Computer-controlled turning and milling, including mill-turn and five-axis work, to ±0.0001″.
Heat treatment
Annealing softens metal so it can be formed again. Induction hardening hardens just the zone that needs it.
Surface treatment
An eight-tank pickling line dissolves the oxide layer (scale) that heat treatment leaves on metal.
Finishing & marking
Lapping for very flat, smooth surfaces. Laser marking for permanent part numbers. Spray painting.
Metrology & QA
Each feature measured against the drawing, with first-article inspection, SPC and lot traceability.
The processes, explained
Ten processes. In plain words.
What each one does to the metal, and the machines we do it on. They are combined in whatever order your part needs.
| Process | What it does | Our equipment |
|---|---|---|
| 01 Cutting | A saw cuts bar and sheet stock to the length needed. | Band saw |
| 02 Press forming | A punch pushes flat metal into a die. The metal stretches into a seamless hollow shape. Nothing is cut away. | 2 × Mankoo and 1 × M.S.S.S. hydraulic presses · 10 T and 20 T presses |
| 03 Trimming | Forming leaves the open rim uneven. Trimming cuts the part to its final length. | Trimming machine |
| 04 Annealing | Forming makes metal harder and more brittle (work hardening). Heating then cooling it makes it soft and workable again. | Continuous annealing furnace · 50 kW induction annealing |
| 05 Induction hardening | An alternating magnetic field heats only the metal inside the coil. Rapid cooling (quenching) locks in hardness there. | 100 kW induction hardening · cooling tank |
| 06 Pickling | A chemical bath dissolves the oxide layer (scale) that heat leaves on metal, exposing clean metal. | 8 tanks · steam heating · overhead crane |
| 07 CNC machining | Computer-controlled cutting tools remove material to the exact dimensions on the drawing. | Ace Designers 540V · 2 × J300 LM · SJE 10 LM slant-bed lathe |
| 08 Lapping | A fine abrasive between the part and a flat plate wears down high spots, leaving a very flat, smooth surface. | Lapping machine |
| 09 Laser marking | A focused laser beam permanently marks numbers or codes into the surface. | Laser marking machine |
| 10 Inspection | Each feature is measured against the drawing. Hardness is tested against the specification. | Profile projector · hardness tester · micrometers · calipers · pitch gauges |
Press forming & deep drawing
Pressure, perfectly applied.
A punch pushes a flat metal disc into a die. The metal flows into a seamless cup. Repeat draws through smaller dies make the wall longer and thinner. Because nothing is joined, there is no weld or seam.

CNC machining
Microns, not millimetres.
Machining more faces in one setup means the part is clamped fewer times, so small errors don't add up. Parts are measured while still on the machine.

Drawn to your drawing
Every dimension, accounted for.
Every size and tolerance on your drawing is a requirement. We machine to each one, then measure and report against it before production starts.
Tolerance
How far a size may vary. ±0.010 means up to 10 µm either way.
FAI
First-article inspection. The first parts are fully measured before production runs.
Cp / Cpk
Statistical measures of how consistently a process holds tolerance, part after part.
Heat treatment
Heat, held to a degree.
A continuous annealing furnace softens whole parts. 50 kW induction annealing softens a selected zone. 100 kW induction hardening, followed by rapid cooling. Heat number, machine cycle and operator recorded for each lot; verified on our in-house hardness tester.
Surface treatment & finishing
Clean metal. Every time.
Pickling dissolves scale in an 8-tank, steam-heated line with overhead crane. Then lapping for very flat surfaces, laser marking for permanent part and lot numbers, and spray painting.
Quality
Quality you can audit.
Every part can be traced back to its material, its machine and its operator.
