CNC Punching Parts
CNC punching parts produced by blanking and piercing on progressive tooling, for high volume components with accurate hole patterns.
- Press range20 to 200 tons
- Material thickness0.25 mm to 6 mm
- Linear tolerance+/-0.01 mm
- Minimum spacing between holes1 to 0.5 x material thickness
- Edge to feature0.4 mm

Product Overview
Punching parts are produced by shearing material with a punch and die, either blanking the outer profile or piercing holes and slots within it. On a progressive tool, the strip advances through several stations so a part is blanked, pierced, formed and cut off in a single press stroke sequence.
Once the tool is proven, punching is one of the fastest and most economical ways to make a metal part in volume, which is why it dominates hardware, electrical and appliance components.
Key Benefits
High Production Speed
Progressive tooling produces a finished part on every press stroke.
Low Piece Cost At Volume
Once the tool is amortised, the per part cost is low and stable.
Accurate Hole Patterns
Hole positions are set by the tool, so they repeat exactly across the whole run.
Combined Operations
Blanking, piercing and forming combined in one tool rather than several processes.
Application Scenarios and Who It Is For
- Electrical contacts and terminals
- Appliance and hardware components
- Automotive clips and brackets
- Furniture and machinery hardware
- Shielding and mounting plates

Manufacturing Process and Quality Control
Drawing Review
Our engineers review manufacturability, confirm tolerances and raise anything in the drawing that would cause a problem before production starts.
Sample Approval
Free samples are offered prior to mass production, with first piece inspection recorded against your drawing.
Production Control
In-process inspection at a set frequency during the run, using the coordinate measuring machine and gauges in our inspection room.
Surface Treatment
Anodizing, sand blasting, polishing, electroplating and powder coating applied in house after deburring and cleaning.
Final Inspection
The finished lot is checked against the drawing before packing, with certification issued for the stages you require.
Packing and Delivery
Protective packing appropriate to the part, dispatched within the agreed delivery date.
Customization Options
- Material — specify a grade from our catalog, or describe the function and our engineers will recommend one.
- Tolerance — standard machining tolerance is 0.005 to 0.01 mm; tighter callouts are discussed at quotation.
- Surface finish — anodized, sand blasted, polished, electroplated, powder coated or as machined.
- Marking — laser engraving and CNC engraving for part numbers and logos.
- Quantity — from a single prototype through to long production contracts.
- Certification — certification provided at each stage on request.

Product FAQ
How close can holes be to each other or to an edge?
Minimum hole spacing is one to half of material thickness, and edge to feature distance is 0.4 mm. Tighter than that risks tearing.
What quantity justifies a punching tool?
It depends on part complexity and material cost. Send your annual volume and we will compare tooling plus piece price against laser cut alternatives honestly.
Do you make the tools in house?
Yes, dies are made in our own machining factory, which is how corrections are handled quickly.
How do I order this part?
Do you offer free samples?
Yes, free samples are offered prior to mass production so you can confirm the part before committing to a run.
