01 / What We Fabricate
The Chassis — Precise Housing for Your Electronics
A rackmount chassis is the precise sheet metal box that holds a single piece of equipment in a 19-inch rack. We fabricate that chassis — accurate, EMI-shielded, and built around the boards and components you'll integrate.
Front & Rear Panels
Front panels (fixed or removable) with cutouts for displays, connectors, switches, and ergonomic handles, plus rear panels with I/O and power-entry openings.
PCB Guides & Mounts
Internal PCB guides, card rails, mounting plates, and standoff provisions — locating the boards, drives, and power supply exactly where they belong.
EMI Shielding & Ventilation
EMI/RFI containment — seam construction, gasket and finger-stock provisions — plus fan mounts and vent perforations for thermal management.
Our scope: the sheet metal chassis
We fabricate the chassis — body, covers, front and rear panels, PCB guides, mounts, and shielding/ventilation features — laser-cut, formed, welded, and finished, ready for integration. Bought-out components such as the motherboard and PCBs, CPU/GPU, power supply, drives, fans, connectors, and electronics are integrated by you or your assembly partner. This is a build-to-print manufacturing service, not a complete server or retail PC case offering. Share the chassis drawings and assembly interfaces so cutouts, guides, and mounting features can be reviewed against your equipment layout.

04 / Manufacturing Process
From Sheet to Precision Chassis
A rackmount chassis lives or dies on dimensional precision, EMI containment, and fit. Our process delivers a chassis that fits the rack and the boards exactly.
01
DFM & Layout
Review your boards, components, U-height, and EMI needs — confirm material, panel cutouts, PCB guide layout, and thermal plan.
02
Laser Cutting
Fiber laser cutting and CNC punching of body, panels, and covers — with precise cutouts, vent perforations, and mounting holes.
03
Forming
CNC press-brake forming to tight tolerances — accurate bends so the chassis fits the 19-inch standard and the boards locate precisely.
04
Welding & Hardware
Seam welding for EMI containment and rigidity, plus self-clinch standoffs, PCB guides, and hardware for board and component mounting.
05
Finishing
Anodizing, sandblast paint, or powder coat, with silkscreen or graphics for labeling — a clean, durable, professional chassis.
06
Inspection
Dimensional inspection of the 19-inch fit, panel cutouts, and board-mount positions, plus finish check before delivery for your integration.
05 / Why It Matters
What Makes a Rackmount Chassis Right
The chassis determines whether the equipment fits, runs cool, and meets EMC. Four things separate a precise chassis from one that causes problems.
Dimensional Precision
A chassis that's off-spec won't fit the rack or the boards. Tight-tolerance forming to the 19-inch standard is what makes the unit slide in cleanly and the components mount right.
EMI Containment
Electronics must meet EMC requirements. Seam construction and gasket/finger-stock provisions contain EMI/RFI cost-effectively — designed in from the start, not bolted on later.
Thermal Management
High-density CPUs and GPUs generate serious heat. Fan mounts, vent perforations, and airflow paths keep the components within temperature limits for reliability.
Board Integration
Boards, drives, and power supplies have to mount precisely. PCB guides, standoffs, and mounting plates sized to your components make assembly clean and reliable.

OEM Procurement & Repeat Programs
Release the Chassis Scope Before Comparing Prices
For AI hardware makers, industrial equipment OEMs and system integrators, the first order and the repeat order need the same controlled interface definition. Enterprise development quantities are welcome for review; this is not a stocked retail PC case.
Pilot and Fit-Up
Identify board and module reference revisions, rack interfaces, connector openings, service paths and the checks required before repeat release. A metalwork fit check does not replace system thermal or EMC validation.
Comparable Quotation
Separate chassis bodies, covers, installed hardware, finish masking, fixtures, inspection records and protected packout. List electronics and bought-out assemblies that remain with the OEM.
Repeat-Order Configuration
Confirm the drawing, BOM and approved deviations at reorder. Material or hardware alternatives need the designated approval; a prototype concession must not silently become the production specification.
Changes After Release
Review affected blanks, formed parts, welded assemblies and finished stock separately. Agree disposition, verification, commercial impact and the first order using the revised configuration.
Enterprise Server Integration
Release the GPU, Rail and Board Interfaces Together
For enterprise computing and AI inference programs, we fabricate chassis bodies, trays, covers, front panels and mounting structures to the released mechanical package. Include the selected components and acceptance setup so the metalwork can be reviewed in its assembled condition.
Rail and Support-Ear Connections
Provide rail part numbers, rack-side attachments, functional datums, finished side clearances, populated mass and service-extension conditions. Agree reinforcement, fasteners and load checks for the specified assembly; there is no universal load rating based only on chassis size.
GPU Modules and PCIe Location
Release the board or riser revision, bracket envelope, mounting-hole groups, standoff heights, guide pins and lead-ins. Identify what locates the module, what retains it and what supports its mass. Check seating before retention hardware is tightened.
Short-Depth Packaging
Include the populated board, drive cage, connector backshells, cable bend guidance and service-tool envelopes. Review installed, assembly and removal paths. A shallow outside dimension alone does not establish component or rack compatibility.
Mixed-Gauge Parts and Preassembly
Specify base, cover, front panel and rail material separately, with their joining and finish requirements. Define subassemblies, inspection stages and supplied hardware. Record any design alternatives before they enter a repeat-order configuration.
Drawing Inputs for a Comparable OEM Quotation
Send a STEP assembly and released 2D drawings, component envelopes, rail and hardware datasheets, finish and masking requirements, critical datum features, prototype and batch quantities, and the agreed inspection plan. Identify who supplies electronics, trial-fit components and fixtures. Separate dimensional sampling, load validation and populated-system compatibility testing.
Our enterprise server chassis customer project documents rail reinforcement, GPU guide features and a revised short-depth layout. Its recorded loads and assembly results apply to that project, not every chassis configuration.
09 / FAQ
Rackmount Chassis FAQ
Can you fabricate a custom GPU server chassis rather than a retail PC case?
Yes. We review enterprise OEM chassis metalwork against the released board and module envelopes, rail interfaces, PCIe references and assembly requirements. Scope can include trays, guide features, front panels and specified installed hardware. Electronics and system integration responsibilities are agreed separately.
How are rail and rack-ear load requirements quoted?
Provide the populated mass, load distribution, selected rail arrangement, support points and service or handling conditions. We review the fabricated attachment scope and agreed validation method. Sample count, deflection limits, unloading checks and test-piece disposition should be stated in the purchase specification.
What is needed to check a short-depth server layout?
Include the actual motherboard or riser, expansion cards, drive cage, connectors, cables and their service envelopes. A trial fit should follow the intended assembly sequence using the selected components or approved surrogates. Mechanical fit does not replace the equipment team's thermal, electrical or EMC validation.
Do you supply complete servers or just the chassis?
We fabricate the sheet metal chassis — body, covers, front and rear panels, PCB guides, mounts, and shielding/ventilation features. The motherboard, PCBs, CPU/GPU, power supply, drives, fans, connectors, and electronics are integrated by you or your assembly partner. We build the chassis with cutouts, guides, and provisions sized to your boards and components.
How is this different from your server rack?
Our server rack is the large cabinet that houses many units. A rackmount chassis is the individual enclosure (1U–6U) for a single piece of equipment — a server, industrial PC, or instrument — that mounts inside that rack. We fabricate both, at their respective scales.
What sizes and standards do you support?
We build to the 19-inch standard in 1U through 6U heights, conformant with DIN 41494 and IEC 60297-3, in depths from compact to deep-body (for storage and GPU builds). We also fabricate custom widths and non-standard sizes where your equipment requires.
Can you provide EMI/RFI shielding?
Yes — we design EMI/RFI containment into the chassis through seam construction and provisions for gaskets and finger-stock, which is more cost-effective than retrofitting shielding later. EMC should be considered at the design stage, and we build it in from the start.
Can you match our board and component layout?
Yes — send us your board dimensions, mounting points, connector and I/O layout, and thermal requirements, and we'll fabricate the chassis with PCB guides, cutouts, standoffs, and fan provisions sized exactly to your components.
Do you support OEM prototypes before production?
Yes. A small prototype order can support an OEM equipment program before pilot or repeat production. Share the intended application, drawings, prototype quantity, and anticipated production batches. MOQ, tooling, pricing, and delivery timing are confirmed for the specific design; there is no universal order threshold.
What should an OEM include in a chassis RFQ?
Include a STEP model and released 2D drawings with the revision, U-height, chassis depth, rack rail or bracket interfaces, board-mount positions, and connector cutouts. Specify material, finish, hardware part numbers, and required inspection points. List prototype and production quantities separately, with the requested delivery schedule and any planned design changes.
For server and AI hardware integration, include the equipment team's component envelopes and airflow requirements. We review the sheet metal features; system thermal and EMC validation remain with the equipment team. Our 19-inch rackmount chassis design guide covers the mechanical interfaces to review.
For modular card or instrument bays, compare custom subrack metalwork. Our AI hardware chassis RFQ guide separates fabricated parts, purchased components and integration responsibilities.
