Sheet metal solutions

Electrical cabinet manufacturing

Make cabinet doors, side panels and trays with cutouts and bends that fit the assembly. Compare laser cutting, CNC press brakes and panel benders for your product mix.

Start with the parts you make

Start with a representative cabinet assembly, then separate its panels from the brackets and internal fittings.

Doors and covers

Review return flanges, corners, hinge positions and the clearance needed to form and remove the part.

Side and rear panels

Consider long bends, joint locations and how each panel will be supported without damaging its visible face.

Mounting plates and trays

Relate cutouts and mounting holes to the final folded shape and to the equipment fitted inside.

Brackets and supports

Check short flanges, tool access and the range of shapes that share a setup.

Connect the part to the process

Assembly fit

Use the finished drawing and flat pattern together. Hole locations, bend allowances and the order of bends affect how the enclosure comes together.

Surface protection

Specify the visible faces and protective film. Tool contact, handling and stacking all belong in the sample-part evaluation.

Product variety

Compare the usual door and tray families with the difficult exceptions. Batch size alone does not describe tool changes or handling effort.

Choose the equipment for each task

Cut the flat geometry, choose a forming method for each part family, then check the interfaces to welding, finishing and assembly.

Cut blanks and openings

Use laser cutting for the panel outline and openings. Material, thickness, small features and the finish needed before bending determine the cutting setup.

Form changing geometries

Consider a CNC press brake for the range of panel and bracket shapes. Review bend sequence, tooling clearance, backgauge access and operator support.

PB-M press-arm panel bender representative configuration

Bend suitable panel families

Evaluate PB-M or PB-A against the panel envelope, flanges, interference and loading. PB-A automatic tool change is relevant when the required tool lengths change across jobs.

Compare panel benders

Panel bending and press-brake bending can serve different parts in the same enclosure. Confirm the proposed machine against representative drawings before assigning the whole cabinet family to one process.

Check the machine against the panel

Compare CNC press brakes and PB-M/PB-A panel benders by model and configuration. Use sample parts to check difficult bends, critical dimensions and surface finish.

Questions before choosing equipment

Which cabinet parts suit a panel bender?

Evaluate the complete panel: material, dimensions, flange heights, return bends, clearances and the way it is loaded and removed. A cabinet label by itself does not establish compatibility.

When is automatic tool change useful?

Compare the tool lengths and combinations required across the planned jobs. PB-A offers automatic tool change; the value of that function depends on the actual panel mix and changeover work.

How should we evaluate cosmetic surfaces?

Identify the visible faces, finish and protective film on the drawing. Include handling, tool contact, corners and stacking in the sample evaluation.

What should we send for a first discussion?

Send a finished-part drawing and flat pattern where available, material and thickness, typical and largest panels, batch pattern and destination. Include the parts that are difficult today.

Prepare a useful production brief

Share a door, side panel and tray from the same cabinet family, including the difficult return flange or corner. Add material, thickness, batch pattern and destination.
