01 / What We Fabricate
Fabricated Aluminum Housings for Enterprise Equipment
This manufacturing route starts with aluminum sheet and drawing-defined cutting, forming and assembly. It suits equipment programs that need custom openings, accessible covers and controlled mounting features. Extruded or die-cast housings are different routes and are not implied by this page.
Industrial Electronics
Formed enclosures with released board supports, connector plates, internal brackets and defined assembly responsibilities.
Removable Equipment Modules
Sheet-metal module shells coordinated with guide surfaces, retention features and the buyer's mating-component references.
Controlled Panel Kits
Common enclosure parts and separately identified panels for equipment variants, with drawing and hardware revisions linked to the kit.
Quote the finished interface, not only an unfinished enclosure size
Provide the mating references, anodizing and masking requirements, selected hardware and appearance criteria. Thermal, electrical and complete-equipment approvals remain defined by the responsible equipment team and the agreed project scope.
02 / Build-to-Print Configurations
Choose the Enclosure Architecture Around Its Interfaces
These are fabrication configurations, not catalog models. Dimensions, material grade, finish and inspection are reviewed from the OEM's requirements.
Two-piece housing Folded Base and Cover
A formed base with a removable cover, attachment flanges and specified hardware. Review installation access and finished mating clearances together.
- Geometry Released CAD
- Access Removable cover
- Finish Project-defined
Instrument enclosure Display and Connector Housing
Fabricated panels and shells with drawing-defined windows, connectors and internal mounting features. Identify cosmetic faces and post-finish fit checks.
- Openings Component-led
- Inspection After finish
- Appearance Approved criteria
Equipment module Removable Aluminum Module
A sheet-metal housing around an OEM module envelope, with specified guide interfaces, fastening and service-removal path.
- Mating Shared datums

03 / Technical Capabilities
Aluminum Enclosure RFQ and Acceptance Matrix
| Material and forming | Specify alloy, temper, sheet thickness, grain-sensitive cosmetic requirements and any bend constraints. Material and tooling suitability are reviewed against the actual geometry. |
|---|---|
| Critical interfaces | Identify display, connector, internal mounting and cover-fit datums. Distinguish individual part dimensions from assembled clearances. |
| Finished-state dimensions | Mark dimensions accepted after anodizing or other finishing. Agree how treatment allowance is determined instead of applying one universal growth value. |
| Masking and contacts | Define thread protection, electrical or thermal contact zones, mask boundaries and the applicable surface condition. Selective masking must be on the released drawing. |
| Threads and hardware | List tapped, inserted or self-clinching hardware with selected part references, installation sequence and inspection. Review minimum sheet and edge requirements from the hardware catalog. |
| Appearance | Identify visible zones, color reference, inspection lighting and acceptance criteria. Define whether multiple parts must match within one assembly or across later lots. |
| Mixed-metal interfaces | Identify stainless fasteners or other dissimilar metals, exposure and the approved isolation or protection arrangement. |
| Commercial package | Provide pilot and repeat quantities, drawing and BOM revisions, required records, packing expectations and requested schedule for review. |
04 / Manufacturing Process
From Equipment Drawing to Repeatable Housing Kit
01
Confirm the Manufacturing Route
Check that the enclosure is intended for sheet fabrication. Separate extruded, cast or machined purchased parts and their supply responsibilities.
02
Review the Formed Geometry
Assess bends, reliefs, hardware access and assembly sequence against the specified alloy, temper and thickness.
03
Release Finish Interfaces
Identify finish type, coating requirements, mask zones, cosmetic faces and the final dimensions that control assembly.
04
Agree Pilot Acceptance
List mating references, measurement state, hardware checks and appearance criteria. Resolve open dimensions before manufacture.
05
Fabricate and Coordinate Finishing
Cut, form and assemble the quoted scope, with treatment and handling aligned to the approved requirements.
06
Inspect and Protect the Kit
Check the agreed final interfaces, identify variants and protect visible faces and mating edges during packing.
05 / Why It Matters
The Finished Enclosure Must Fit the Equipment
An aluminum enclosure is accepted at its functional interfaces, not solely by the dimensions of an unfinished blank.
Anodizing and Mating Features
Treat the finishing allowance as a project input. Small windows, sliding interfaces and threaded features need a defined post-treatment acceptance method.
Thread Installation
Select hardware for the sheet and service task. Define whether installation occurs before or after finish and how protected threads are verified.
Color and Surface Zones
Review appearance with an agreed reference and inspection condition. A color name alone does not control visible variation across different parts or lots.
Service and Replacement
Keep tool access, cover removal and replacement-panel compatibility in the interface review, especially for later equipment variants.

The Customer Challenge
Variable dimensional growth during anodizing changed window and connector fits; lot-to-lot color variation and obstructed threads added assembly problems.

Custom Aluminum Enclosure Questions
Do you make folded aluminum enclosures or catalog extruded boxes?
This page covers custom fabricated aluminum sheet-metal enclosures and the assembly scope identified in the quotation. An extrusion, casting or machined component must be identified separately if it is part of the equipment.
Which aluminum alloy and thickness should I specify?
Provide the application's requirements and released design. Alloy, temper, thickness, bend geometry, finish and hardware compatibility are reviewed together. There is no single grade or thickness suitable for every enclosure.
Can critical openings be inspected after anodizing?
Yes, specify those characteristics and their acceptance method in the RFQ. Treatment allowances, protected threads and mating references should be agreed before the final manufacturing package is released.
Can I order a pilot before production?
Yes. Send the pilot quantity, anticipated repeat quantities and any differences in inspection or documentation. Pricing and timing depend on the geometry, finish, hardware and agreed deliverables.
Does anodizing guarantee electrical insulation or corrosion performance?
A finish specification alone does not establish complete-equipment performance. Provide the required treatment, exposure, contact interfaces and verification scope for review by the responsible engineering team.
What should purchasing send for an accurate quote?
Send CAD and drawings, alloy and temper, thickness, finish and masking details, hardware BOM, mating references, cosmetic acceptance criteria, quantities and required inspection records.
