Instrument & Portable Cases

Desktop instrument housings, handheld and portable cases, transit enclosures and carrying frames — light enough to move, stiff enough to survive being moved, and finished so the product looks right on a bench.

Product Category

Small Parts, Tight Tolerances

A small enclosure amplifies every error. On a 300 mm instrument case the panel gap, the corner radius and the position of a single connector are all visible at arm's length, and there is no structure behind them to hide a poor fit.

We build small cases with the same process as large ones: laser-cut flat patterns, press-brake forming with radiused corners, dressed welds where they show, and hardware fitted before delivery. Where a case has to be carried, handles, corner protection and transit protection are part of the build rather than an afterthought.

Production Route

How This Moves Through the Workshop

Small housings are reviewed for corner radii, panel gaps and service access before cutting, because these are the details that show. Flat patterns are laser cut and formed with radiused corners, visible joints are welded and dressed, and the case is checked for squareness and gap before finishing. Front panels and bodies are finished separately, printed where required, then hardware, handles and fittings are assembled and the case is inspected against the drawing.

  • Drawing review with DFM feedback before production release
  • Fiber laser cutting of the complete flat pattern in one set-up
  • CNC press-brake forming, welding and grinding
  • Coating applied before gaskets, hardware and glass are fitted
  • First-article and sample inspection recorded for each batch

FAQ

Common Questions

Yes. Laser cutting and press-brake forming do not need a die, so a first-off case can be produced as a single unit and the same program then runs the production batch. Tooling cost is limited to any special press-brake tooling the geometry requires.

Corners are formed with a radius, or built from a folded and welded joint that is dressed flush where the corner is visible. Very small radii on thick material are limited by the press-brake tooling, and we confirm the achievable radius at drawing review.

We provide the mechanical provision — recess, flat land, aperture and legend printing — so a membrane or overlay can be fitted. The membrane switch itself is usually handled by you or a specialist supplier, and we confirm the recess depth and tolerance to suit it.

Aluminum is the usual choice where weight matters, with 1.25 to 2.0 mm wall thickness giving a good stiffness-to-mass balance. Coated steel is chosen when cost leads and the case is not carried far. Stainless is used when the environment is corrosive or the case is treated roughly.
