Anything that generates heat inside an enclosed space has to vent it somewhere. Motors, drives, engines, pumps, compressors, batteries, transformers, switchgear, lighting, ovens and hydraulic packs all do it, and the housing around them has the same job every time: let the heat out, keep the weather and the debris outside.
A punched louvre does both. It is formed straight into the panel by a forming tool on our punch press, so there is no separate part to buy, fit or fasten.
Where louvres earn their place
We punch louvred panels for:
- Switchboards, control cabinets and battery or inverter enclosures
- Generator, pump and compressor housings
- Plant room panels, transformer kiosks and comms cabinets
- Machine guards, gearbox and motor covers
- Mining and agricultural equipment panels and canopies
- Vehicle and trailer body panels, toolboxes and service bodies
- Commercial kitchen and refrigeration casings
- HVAC casings, ducting covers and roof plant screens
If the build has a heat source in a box, on a skid or under a canopy, it is the same job for us.
What you get
Faster turnaround. The louvres go in during the same run as the holes, cut-outs, tapped holes and the outer profile, in one setup on one machine. There is no second operation, no separate louvre part, and nothing waiting on another supplier.
A better result. The hood over each opening is angled, so falling rain runs off the outside of the panel instead of through it, and wind-driven dust, leaves and insects are kept out. It also blocks the direct line of sight into the enclosure.
Lower cost per part. One setup, one machine, one handling step. Across a production run that is the difference between a panel that is competitive and one that is not.
Formed on the punch, cut by the laser, in one setup
A laser removes material, so it can cut an opening but it cannot form the hood that makes a louvre work. A louvre has to be pressed by a forming tool on a punch press.
On the TRUMPF TruMatic 6000 combo machine we run at Yatala, both happen on the one machine: the laser cuts the profile and any complex geometry, the punch head forms the louvres and every repeating feature, and the sheet never leaves the table in between. Part one and part two hundred come off the same way.
FAQs
Can a laser cut a louvre?
No. A laser removes material, so it can produce the opening but not the formed hood. Louvres are pressed by a forming tool on a punch press, which is why we form them on the punch head of the TruMatic 6000.
Can louvres be punched into stainless and aluminium?
Yes. Mild steel and zinc-coated steel are the most common, aluminium is common on lightweight covers, and stainless runs well with the right form radius.
Louvres or perforation?
Louvres suit anything exposed to weather, because the hood sheds rain and blocks wind-blown debris. Perforation suits sheltered and indoor panels where maximum airflow is the priority. We run both on the same machine, so you can specify either, or both on the one panel. See perforation patterns and open area for how we set a perforated field.
