Complex patterns. No dedicated tooling required.
We punch sheet metal with CNC turret precision, creating complex patterns of holes, slots, louvres, and forms without expensive dedicated tooling. Fast, accurate, and cost-effective for prototypes through to production volumes – built to work and built to last.
Our CNC metal punching service produces accurate holes, slots, cut-outs, and formed features across a range of sheet materials. Digital programming ensures consistency across single parts and high-volume batches. Dimensional accuracy at this stage underpins everything that follows. Components are produced efficiently, inspected carefully, and prepared for bending, fabrication, or assembly as required.
- Hole punching — Round, square, rectangular, and oblong apertures
- Slotting and notching — Elongated openings and edge cutouts
- Perforation patterns — Ventilation grilles and decorative perforations
- Louvre forming — Pressed ventilation slots with directional airflow
- Countersinking — Recessed holes for flush-fitting fasteners
- Embossing and forming — Raised or depressed features for stiffening
- Multi-stage punching — Complex patterns with multiple tool changes
- Prototype to production — Single sheets to high-volume runs.
Drawings, hole patterns, tolerances, and material specifications are reviewed in detail. We confirm programming requirements and check for potential clash or distortion risks.
CNC punching programmes are created to optimise accuracy and efficiency. Tooling is selected to suit material type, thickness, and feature requirements.
Sheet material is processed under controlled settings to maintain consistency. Hole position, edge quality, and dimensional accuracy are monitored throughout the run.
Completed parts are checked against specification before progressing to the next manufacturing stage. Where required, documentation supports traceability and batch verification.

CNC punching delivers speed that other cutting methods can't match, when you need multiple features across one sheet. Drilling fifty holes individually takes time and risks positional drift, whereas punching creates the entire pattern in minutes with absolute consistency. Traditional press tools can cost thousands and take weeks to manufacture, whereas CNC punching uses standard tooling from our existing library. This makes it economical for prototypes and low volumes where dedicated tooling would never pay back. The process also enables functional features like louvres and embossing that add strength or ventilation without additional assembly steps. Material waste is minimal because holes can be closely nested and scrap falls cleanly away. Punching integrates seamlessly with our bending operations too – we punch the flat pattern, then form it into the final three-dimensional shape. For parts requiring both holes and bends, this combination delivers complete components faster than separate operations at different suppliers. The result is shorter lead times, lower costs, and parts that arrive ready for assembly or installation without additional machining or finishing work.
Your punching questions, answered
Specifying metalwork isn't always straightforward. Here are the questions we hear most often — and the honest answers.
We run an AMADA EMZ 3510, which handles mild steel, stainless steel, and aluminium across a range of gauges. It's set up for standard sheet sizes and can process high volumes without losing accuracy. If you're working with non-standard material or tight tolerance requirements, get in touch and we'll confirm what's possible.
Punching is generally the smarter choice for repetitive hole patterns, forming features that laser can't do, and higher-volume production runs where speed and cost per part matter. Laser tends to win on intricate profile cutting and one-offs. We offer both, so we'll recommend whichever process suits your job rather than defaulting to one.
Yes. CNC punching isn't limited to simple round holes. We can produce louvres, countersinks, embosses, and complex perforated patterns — all programmed and repeatable. If a feature can be achieved with tooling rather than secondary operations, we'll recommend it. It's usually faster and more cost-effective.
