Custom Mounting & Backing Plates
A component, a thin panel, or an enclosure opening needs a flat face that holds a hole pattern and stays true. K-Display makes mounting, backing, gland, and cable entry plates cut to your hole pattern, delivered loose, with hardware installed, or kitted with an enclosure or bracket set.
The plate is a face and a hole pattern
A mounting plate carries components at a hole pattern. A backing plate sits behind a thin panel at a fastener location and spreads the clamp load. A gland plate bolts over an enclosure opening and carries the holes for glands and conduit.
Two relationships decide fit. The hole pattern has to match the component or panel it mates with, and the mounting or sealing face has to stay flat and, where it bonds or gaskets, bare metal. The hardware pressed into the plate and the coating both act on one or the other.
The backing plate sits behind the thin panel at the mounting holes. It gives the fasteners a broader clamping surface, so the equipment is secured through the panel and plate together.
Plates we make
- Mounting plates
- Flat plates, or plates with a stiffening return edge, with the hole pattern, slots, and cutouts the components need and self-clinching nuts, studs, and standoffs installed.
- Backing plates
- Plates that sit behind a thin panel or enclosure wall at a fastener location, so the fastener clamps against the plate and not only the sheet. Matching hole patterns, with captive hardware where the fastener needs thread engagement.
- Gland and cable entry plates
- Bolt-on plates that close an enclosure opening. Round holes for glands and conduit, rectangular or D-shaped cutouts for connectors and entry frames, and a bare pad with a hole or stud for a bonding lug.
- Adapter and cover plates
- Plates that convert one hole pattern to another, and blank-off or access plates that close an opening, cut to the pattern with any hardware installed.
What has to be right on the plate
- Hole pattern and hardware
- The mating component’s mounting drawing sets the pattern, so we cut from it or a template, not an earlier plate. Self-clinching hardware depends on sheet material, thickness, and distance from edges and holes, and installs from one face, so we confirm hardware and material together before cutting.
- Cutouts and entries
- Gland, conduit, and connector holes are sized to the accessory that goes in them, and plate thickness sets how much thread the accessory engages. A backing plate’s holes follow the fastener it takes and the panel it sits behind, so we set both from those parts.
- Datum face and flatness
- The face that mounts or seals is the datum, and a thin plate can move when it is cut, formed, or welded. We identify that face at review and sequence cutting, welding, and coating around it.
- Hole sizes and bare faces
- Coating adds thickness inside every hole and over every unmasked face, which cuts thread engagement and can spoil a fit. We size holes that take a fastener, a pin, or a mating fit for the finished plate, and mask the mounting face, gasket land, bonding pad, and threads.
From cut pattern to coated plate
Hardware, masking, and coating all run in our shop, so hole sizes and masked faces are settled at review, while the pattern can still change.
Review the plate against its mating parts
Check the hole pattern against the component and structure drawings, confirm hardware and material together, and identify the datum face and cosmetic face.
Cut and install hardware
Laser cut or punch the plate and its cutouts, form any return edge, install the nuts, studs, and standoffs, and weld any joined features.
Mask, coat, and unmask
Mask the bare faces and threads, powder coat, unmask, and check the hole pattern and hardware against the mating drawing.
Review each mating interface
Supply the mounting pattern and the accessory cutout drawings together. Mark the face that must sit flat, any gasket or bonding area that stays bare, and whether the hole dimensions apply before or after coating.
Accessory cutouts follow the glands and connectors; the perimeter follows the enclosure opening. Keeping that mounting face flat and preparing the specified bare areas lets the plate fit its hardware and sealing interface.
What the plate has to match
A model, a flat pattern, or a plate to copy is enough to begin.
- Model or plate
- STEP, DXF, or PDF, or an existing plate to match, with material, thickness, hole pattern, cutouts, and the datum face.
- Tolerances
- Hole position and flatness, where the assembly depends on them.
- Hardware and accessories
- Captive hardware part numbers, gland or connector part numbers, and the panel thickness behind a backing plate.
- Finish and bare faces
- Coating color and gloss, the cosmetic face, whether hole sizes are before or after coating, and the faces and threads to leave bare.
- Quantities and delivery form
- Order quantity, delivery date, and loose, hardware installed, or kitted.
