01 / What We Fabricate
Fabricated Subrack Metalwork, Not a Complete Electronic System
This route covers custom sheet metal components around an OEM's modular equipment architecture. It is distinct from a catalog subrack, a complete server or an electrical backplane assembly.
Industrial Computing
Sheet metal interfaces around defined compute, I/O and service modules, with the equipment configuration supplied by the OEM.
AI Hardware Integration
Custom trays, support brackets and covers reviewed against released component envelopes and integration responsibilities.
Platform Variants
Common metalwork and separately identified module fillers or front panels where the approved population and compatibility rules are explicit.
Supply boundary: custom sheet metal parts and quoted mechanical kits
The page does not offer an unspecified complete server, electrical backplane or universal standards-compatible subrack. Purchased components and integration can only be included when identified in the quotation. The responsible equipment team defines system thermal, electrical, EMC and safety requirements and the verification scope. Applicable quality and compliance documentation is available for project review.
02 / Drawing-Defined Components
Specify the Parts and Interfaces You Need
The configurations below illustrate fabrication scopes, not stocked models or dimensional standards. Identify purchased rails, guides, handles and connectors separately from the metalwork to be manufactured.
Structure Folded Side Plates
Formed side plates with drawing-defined flanges and mounting patterns for the selected guide supports or crossmembers.
- Reference Shared datums
- Form Released geometry
- Interfaces OEM pattern
Module Face Front and Blanking Panels
Module front plates and solid filler panels with specified apertures, fastening, overlap and finish zones.
- Population Variant-linked
- Cutouts Component-led
- Finish Defined faces
Internal Support Mounting Brackets and Plates
Bent supports and rear interface plates reviewed against mating-component references and agreed installation access.
- Attachment Approved BOM
- Location Defined datum
- Supply Metalwork scope
Enclosure Parts Covers and Lower Trays
Formed covers, ventilated panels and shallow trays with specified fasteners, opening zones and removal paths.
- Access Service-led
- Openings OEM design
- Delivery Parts or kit
03 / Technical Capabilities
Subrack Metalwork RFQ Inputs
| Supply boundary | List manufactured panels, brackets, covers and trays; identify purchased rails, guides, hardware and any included mechanical assembly separately. |
|---|---|
| Mating architecture | Module outline, guide and connector references, mounting pattern, installed envelope and applicable standard or catalog-part revision. |
| Materials and finish | Drawing-specified aluminum, coated steel or stainless steel; grade, thickness, coating, cosmetic zones and masked features reviewed against the design. |
| Panel variants | Population matrix, front-panel identifiers, blanking rules, fasteners and the allowed interchangeability of configurations. |
| Service interfaces | Module and tray withdrawal direction, cable disconnection, tool access, retention and the approved service sequence. |
| Electrical and thermal inputs | OEM-defined bonding features, connector envelopes and opening requirements; assign system performance and compliance verification explicitly. |
| Inspection state | Released datums, finish and restraint condition, reference components or gauges, and the records included in the quotation. |
| Pilot and repeat orders | Quantity by configuration, drawing and BOM revisions, approved substitutions, packaging and requested schedule for review. |
04 / Manufacturing Process
Release a Coherent Mechanical Package
01
Separate the Supply Lines
Distinguish fabricated parts, bought-out components, assembly labor and verification deliverables before comparing quotations.
02
Fix the Mating References
Review module, guide, connector and mounting interfaces against one controlled assembly configuration.
03
Review Service and Variants
Connect each front panel or filler to the equipment population, removal path and retention method.
04
Agree Finish and Acceptance
Identify mask boundaries, visible surfaces, finished-state dimensions and any reference fit check.
05
Fabricate the Quoted Scope
Cut, form, finish and assemble the included metalwork, with agreed inspections and records.
06
Identify Repeat Kits
Link delivered components to drawing and BOM revisions, distinguish variants and protect mating surfaces in packout.
05 / Why It Matters
Interfaces Matter More Than the Subrack Label
An outer size alone does not define module compatibility. Review the specific geometry and reference components that the finished metalwork must meet.
Guide-to-Connector Relationship
Agree how guide supports and rear interfaces are located; a fabricated bracket does not establish connector alignment on its own.
Populated and Empty Bays
Identify which configuration requires a solid filler, a vented panel or another closure. Thermal behavior remains a system-level verification task.
Service Removal Path
Check the actual module, cable and tool envelope in the stated installation, including the retained position of removed parts.
Coated and Contact Surfaces
Specify mask limits and surface condition at mating or bonding features without treating a bare patch as proof of electrical performance.

A B2B Fabrication Route for Controlled Equipment Programs
01
OEM Scope Rather Than Retail Accessories
The quotation follows a released equipment configuration and supply boundary, not a universal consumer PC upgrade.
02
Pilot and Repeat Requirements
Reference parts, fixtures, records and configuration quantities are reviewed explicitly; there is no assumed universal MOQ or lead time.
03
Quality Documentation
DRAmetal / Shenzhen Shixin holds ISO 9001 certification. Applicable certification documentation is available on request, with order-specific inspection records agreed before release.
04
Clear Variant Ownership
A change to a guide, module, fan or connector can affect the metalwork. Keep the revised interface and approval boundary visible in the BOM.

09 / FAQ
Subrack Metalwork Questions
Do you supply a complete catalog subrack or backplane?
This page covers custom sheet metal components and the mechanical assembly explicitly included in a quotation. Rails, guides, electronics, backplanes and other purchased items must be identified separately; they are not implied by the product name.
Can parts be made for a 19-inch subrack arrangement?
Yes, drawing-defined metalwork can be reviewed for that architecture. A 19-inch mounting designation does not define all guide, module or connector interfaces. Provide the applicable dimensional references, mating parts and acceptance requirements.
Which files should an OEM send?
Send released CAD and drawings, module and guide references, material and finish, hardware BOM, population variants, service constraints, quantities and the required inspection records. List unresolved interfaces so they are visible in the quotation.
Can the same frame use different module front panels?
It can be reviewed as a controlled variant family. Define which interfaces are common and which panels, fillers or hardware change. Similar external dimensions alone do not establish interchangeability.
Can I request a small enterprise pilot before repeat production?
Yes. Share the actual pilot and repeat quantities and their different verification needs. Reference parts, fixtures, finish and records are scoped with the quotation rather than assumed from quantity alone.
Does a perforated cover or masked pad prove thermal or EMC performance?
No. Those are specified mechanical or surface features. The responsible equipment team must define the complete system configuration, acceptance criteria and verification scope; relevant certification and compliance documents can be provided for project review.
