Type
Machine housings, guards, cabins and covers
The sheet metal around a machine: a cladding set with louvred vent panels, a closed cabin of flat panels with lifting handles, a housing of thick plate with bolted liner plates, a guard enclosure with rounded hoods, a door frame with three openings, a cover with ventilation slots, a machined housing full of bores. Thinner material and tighter tolerances than a frame, so folds replace welds wherever the geometry allows.
The gallery holds housings and guards from a cover of a metre to a cladding set of five and a half metres.
What the drawing must show
A part like this is priced from the drawing. The quotation is fastest when it carries:
- The flat pattern or the folded part drawing with the sheet thickness and the material grade
- Which welds are seen and must be ground flush, and which are left as laid
- Openings, louvres and slots with their positions, and the hardware fitted to them
- For a machined housing, the bores and faces with their tolerances
- The finish inside and outside, and the colour

Each model is rendered from its own geometry in raw steel, without paint, and is shown as a still. Customer names, machine designations and drawing numbers are not published; part lists and files are not offered. The interactive model above this section is a parametric example, not one of these.
How a part like this goes through the hall
Sheets are laser cut on a 2 000 x 4 000 mm bed with bend reliefs and tab and slot location, folded on a 400 t press brake over 6 050 mm, and welded with the seen welds ground flush. A housing with bores is machined after welding on a boring mill. Painting is in house in a booth of 7 900 x 5 000 x 4 890 mm, cured at 75 to 80 °C; stainless from 3 to 16 mm where the drawing asks for it.
