Injection Molding
Tooling and molding for your repeat plastic parts.
YOUR CHASSIS. YOUR RAILS. YOUR SERVICE SPACE.
Custom Data Center Hardware for Your Server & Rack Interfaces
Review your chassis, mounting brackets and cable-support parts around the installed assembly. When choosing a custom server chassis manufacturer, share the released drawing, mating hardware and acceptance requirements together.
4 Interfaces to Confirm Before You Release Your Chassis
01 · Rack envelope
State the allocated U height and actual usable depth.
02 · Rail & mounting
Identify mating rail kits, rack ears and fastening access.
03 · Air & cables
Reserve openings, connector space and service access.
04 · Finish & records
Define protected contacts, appearance and sample evidence.
For your data center rack hardware manufacturer review, distinguish the fabricated component from complete server, rack and electrical-system approval.
Choose the Hardware Scope for Your Assembly
Chassis trays & covers
Review formed edges, removable covers, standoffs and cable openings.
Your input: assembly envelope, material, thickness and released revision.
Custom server mounting brackets
Match rack ears, locating slots and fastening faces to the actual mounting hardware.
Your input: mating rail model, hole pattern and installed loading requirements.
Cable & power supports
Identify cable-management brackets, support plates and protected connection areas.
Your input: routing, bend clearance, insulation interfaces and assembly sequence.
Manufacturing scope is confirmed from your part. Rack load, EMC, electrical safety and thermal performance need their own defined approval.
Compare Rack Height Without Losing Sight of Depth
U height tells you the nominal vertical allocation. It does not confirm your chassis depth, rail-kit range, rear connector clearance or door access.
Nominal rack-space height
1U = 44.45 mm · zero baseline, 0–180 mm
Height = U × 44.45 mm. These are rack-space references, not finished chassis dimensions or LK MFG tolerances. Allowances and mounting details follow your selected equipment specification.
4 Dimensions Your Drawing Still Needs
- Front-to-rear mounting-plane spacing.
- Rail kit adjustment and extension range.
- Chassis body depth plus rear cables and plugs.
- Service clearance and door/PDU interference.
A nominal 19-inch interface does not establish the outside width of a cabinet or guarantee compatibility.

Match Your Rail Kit Before You Add Mounting Holes
For custom server mounting brackets, identify which surfaces locate the chassis and which fasteners only clamp it.
- Confirm front and rear rack mounting positions.
- Review slot travel, hole access and tool clearance.
- Check insertion, removal and full-extension service access.
- Keep critical mounting faces clear of unintended coating buildup.
Share the mating rail drawing or approved interface dimensions. A product name alone may not define the installed geometry.

Compare Processes Around Your Geometry & Quantity
For server chassis sheet metal fabrication, review bend access, formed dimensions and joining before choosing the production route.
| Your part feature | Route to review | Decision for your drawing |
|---|---|---|
| Thin trays, covers and mounting ears | Laser cutting and forming | Thickness, bend orientation, hardware and edge requirements |
| Locating blocks or close mating faces | CNC machining | Datums, tool access and critical dimensions |
| Repeated lengthwise rail or support section | Extrusion plus secondary machining | Existing/new profile, cut length and end features |
| Multi-part frame or bracket group | Joining and assembly | Fixtures, distortion control and final mating checks |
Tooling investment, economical quantity and lead time require your geometry and order scope; no universal break-even quantity is implied.
Define Finish, Contact Areas & Electrical Scope Together
Sheet-metal grade & condition
State the governing material specification, thickness, finish and cosmetic faces. Confirm substitutions before manufacture.
Coating & bonding faces
Mark masked contacts, threads and mating surfaces. Define the required bonding verification with the assembly owner.
Copper busbars for data centers
Review grade, bend geometry, hole pattern, coating and insulation interfaces. Ampacity, temperature rise and electrical safety cannot be inferred from a material certificate or appearance.
Material properties alone do not establish an assembly rating. Define electrical and mechanical acceptance separately.
Approve the Assembled Fit & the Records You Need
01 · Drawing
Released revision, mating dimensions and assembly configuration.
02 · Sample
Rack ears, cover fit, fastener access and selected interfaces.
03 · Finish
Agreed appearance sample, protected contacts and packing.
04 · Report
Required dimensions, sampling and agreed inspection records.
A dimensional report does not validate complete server performance, EMC, electrical safety or rack loading.
Review inspection documentation →6 Inputs for Your Hardware Review
- CAD and controlled drawing revision.
- U allocation, usable depth and mating rail details.
- Material grade, sheet thickness and final condition.
- Coating, masked contacts and appearance sample.
- Sample quantity and expected repeat demand.
- Inspection, assembly and packing requirements.
Answers Before You Specify
Do standard U heights guarantee that my chassis fits?
No. Compare the nominal allocation with the actual chassis dimensions, rail kit, hole pattern and required clearances. Use your released interface specification.
What information is needed to quote custom server hardware?
Provide the CAD model, controlled drawing and revision, material and thickness, finish and masking requirements, trial and repeat quantities, mating hardware and required records.
Can coating affect rack and chassis fit?
Review the specified coating on mounting faces, holes, threads and bonding contacts. Confirm masking and final-condition acceptance before sample approval.
Does LK MFG supply a complete certified data center rack or server?
This page concerns manufactured components reviewed to your drawing. Complete-system design, ratings, certification and approval remain a separately defined project scope.
