Custom Control Panel Enclosures

A control panel enclosure holds a subpanel of drives, relays, and terminals behind a door that has to close on its gasket and clear every device mounted on it. K-Display builds the cabinet body, door, and subpanel from your drawings, for wall or floor mounting.

Control panel enclosures we build

Indoor control cabinets, wall-mount or floor-standing, cut and formed from carbon steel, galvannealed steel, galvanized steel, stainless steel, or aluminum. Each has a hinged door cut for disconnect handles, pilot lights, and an HMI, and a flat subpanel held on studs in the body. A cabinet leaves the dock bare, powder coated, or assembled with the door hung and the hinges and latches installed.

Field wiring lands in the junction boxes we make, and an HMI moved off the door goes in an operator console.

Control panel enclosure parts we make

Wall-mount and floor-standing bodies: Formed or welded shells with door returns, gasket lands, and mounting feet or a floor base.
Doors with device cutouts: Doors cut for disconnect handles, pilot lights, and HMI, with the hinge and latch mounting points.
Subpanels: Flat mounting panels for the drives and relays, cut to the component layout.
Gland plates: Removable plates punched for cable glands and conduit fittings.

Door seal, subpanel, and ground faces

Gasket land: A door seals only where the gasket land stays flat. Weld heat can bow a land or a door return, and the gasket then stays uncompressed at that spot.
Subpanel and door clearance: Device depth, wire duct, and door-mounted devices share one interior. A device that clears with the door open can foul it closed, and the door then stops short of the body.
Subpanel removal: A subpanel that slides out through the door opening can be wired on a bench. A fixed subpanel is wired inside the cabinet, where the door swing limits the room to work.
Bonding faces: Powder covers every surface it reaches. A ground stud face left unmasked is coated, and a coated face does not make electrical contact.

Body, hardware, then the door

Hardware installation and powder coating run in one shop, so studs and clinch nuts go into bare metal before the powder does and the ground faces are masked first.

Cut and form
We laser cut the body, door, and subpanel, punch the device cutouts, and form the door returns and gasket lands.
Weld and stud
We weld carbon steel, stainless steel, and aluminum bodies and hinge brackets, then install the studs and clinch nuts.
Coat, then assemble
We powder coat the shell with the ground faces and stud threads masked, then hang the door, fit the latches, and set the subpanel for an assembled cabinet.

Check the mounting-panel removal path

A mounting panel can fit inside the cabinet yet be difficult to remove once populated. The opening returns reduce the passage available, while components and wire ducts add depth to the plate. Check the complete assembly through that opening, with the door in its removal position.

In the assembly review, follow the panel from its rear mounting points until it clears the enclosure. Account for releasing the mounting hardware and for any connections that cross from the panel to the cabinet. A bare-plate fit check cannot show these constraints.

The populated panel must pass through as a complete assembly, so its removal path needs room for component depth as well as plate size.
