01 / What We Fabricate
Medical Chassis Bases, Frames and Mounting Trays
Choose this route for the base or frame carrying equipment mounting interfaces. Local cosmetic covers belong on our housing-components page; a coordinated outer frame and panel system belongs on the complete-enclosure page.
Module Support Frames
Internal rails, crossmembers and brackets coordinated around released module interfaces.
Mounting Trays
Fixed or removable trays with controlled attachment points and service-clearance requirements.
Mechanical Chassis Kits
Bases, rails, trays and approved hardware delivered as loose parts or a quoted mechanical subassembly.
Supply boundary: the internal sheet metal structure
DRAmetal fabricates the released chassis metalwork. This is not a complete medical device, a retail equipment base or an automatically load-rated assembly. Provide the applicable load cases, mounting requirements and verification scope. The OEM or responsible design authority retains final design approval and device validation; any additional engineering or test support must be agreed in writing.
02 / Chassis Supply Scope
Four Internal Structure Configurations
These are representative fabrication scopes, not stocked models or rated-load products. Material, geometry, joining and verification are confirmed for the released design.
Base Benchtop Instrument Bases
Folded bases and mounting platforms for diagnostic or laboratory equipment, with interface pads and attachment features defined by the OEM.
- Interface OEM datums
- Finish Drawing-defined
- Delivery Base or kit
Frame Internal Module Frames
Formed rails and crossmembers supporting the specified module layout. The OEM supplies loads and acceptance requirements; structural verification is separately scoped.
- Layout Released assembly
- Joints Welded or fastened
- Records As agreed
Service Serviceable Mounting Trays
Removable sheet metal trays and support features, coordinated with the customer's slide, hardware and service-access requirements.
- Movement OEM-defined
- Hardware Approved BOM
- Check Quoted fit-up
Assembly Reinforced Base Assemblies
Base structures with drawing-defined returns, reinforcement and mounting features. No generic payload or stability rating is implied.
- Loads Buyer inputs
- Condition Final assembly
- Packout Protected interfaces

Inputs That Make a Medical Chassis Quote Comparable
| Fabrication scope | Internal bases, rails, frames, trays, mounting plates and reinforcement; identify excluded outer covers and electronics. |
|---|---|
| Materials | Project-specified stainless steel, aluminum or coated steel; grade, thickness and condition reviewed with the geometry. |
| Load inputs | OEM-defined masses, mounting reactions, transport and operating conditions where applicable; no default payload rating. |
| Critical interfaces | Mounting patterns, datum references, controlled pads, module clearances and service paths. |
| Inspection state | Define free, supported or fastened condition, final finish state and the approved mating reference. |
| Joining and hardware | Drawing-defined welds or mechanical joints; included hardware and customer-supplied items listed separately. |
| Documentation | Agreed dimensional, material, first-article and configuration records; certification documentation available on request for the applicable scope. |
| Delivery | Loose structural parts, welded or bolted subassemblies, or revision-identified mechanical kits as quoted. |
| Datum and fixture agreement | Identify the functional locating surfaces and features, then specify free-state or restrained inspection, support points and the reference fixture revision. |
| Hole patterns across folds | Control mounting-hole relationships from the assembly datum system. Distinguish position, face orientation and mating clearances instead of tightening every dimension. |
| Profile and angular interfaces | Identify which cover or mounting surface needs profile or perpendicularity control and the extent of the controlled area. Agree the finished state and measurement method. |
| Tolerance-stack decision | Use worst-case limits where required; use statistical models only with stated distribution, centering and independence assumptions. Confirm which team owns assembly acceptance. |
| Tab-slot and joining review | Define intended locating clearance, weld access, joint sequence and final inspection. A self-locating tab does not remove distortion or dimensional verification needs. |
04 / Manufacturing Process
From Released Interfaces to a Controlled Chassis Delivery
01
Define the Boundary
Separate internal structure, outer housing, bought-out hardware and OEM integration tasks.
02
Review Geometry and Loads
Review the supplied drawing, load requirements, joining route and manufacturing access; resolve missing design inputs.
03
Confirm Inspection
Agree datums, support conditions, critical features, records and any customer reference fixtures.
04
Fabricate the Structure
Cut, form, join and finish the approved metalwork; hardware and assembly follow the released scope.
05
Verify Agreed Interfaces
Check specified mounting features and quoted fit-up conditions without treating them as complete device validation.
06
Release by Configuration
Identify parts or kits by the agreed revision, preserve interfaces during packout and document approved deviations.
05 / Why It Matters
Control the Interfaces Hidden Behind the Cover
Internal metalwork determines how modules locate and how a device can be assembled and serviced. Cosmetic approval of the outside cover does not verify the chassis interfaces.
Mounting Surfaces
Specify the functional areas and their inspection state instead of relying on an undefined general flatness request.
Assembly Access
Check hardware and tool paths with relevant module obstructions and the intended sequence.
Finish at Interfaces
Define masked pads, contact areas and final finished dimensions where they affect assembly.
Configuration Changes
A changed module or tray can affect frame stock, fixtures and mating panels; review the complete affected configuration.
Inspection Matrix Before Pilot Release
Connect each critical mounting interface to its datum, tolerance, measurement state, method and report field. Mark unresolved inputs rather than leaving acceptance to an informal fit check.
Mating Parts and Revision Control
Identify the OEM module or approved surrogate used for fit review. Preserve that reference with the chassis drawing, fixture and hardware revisions when repeat orders are released.

A Defined Fabrication Route for Enterprise Equipment Programs
01
Medical OEM Scope
The RFQ centers on drawing-led components for equipment manufacturers and their integration partners.
02
Prototype and Repeat Orders
Enterprise pilot quantities and repeat batches are both reviewed against their actual deliverables, not a generic volume promise.
03
Interface-Led Review
Manufacturing and inspection are scoped around the mounting features, assembly state and records that the project requires.
04
Clear Responsibilities
Design authority, structural testing, electronics integration and final device validation are assigned explicitly in the project scope.

Medical Chassis Fabrication Questions
How is a medical equipment chassis different from a housing?
This page covers internal bases, frames and mounting structures. A housing covers or protects a module or equipment exterior. They may be supplied together, but their interfaces and acceptance requirements must be defined separately.
Can you quote an enterprise prototype or pilot?
Yes. Send the released drawings, intended quantity and pilot objectives. Sample, fixture, inspection and repeat-order requirements are reviewed separately; no universal minimum quantity or schedule is implied.
Do these chassis have a standard rated payload?
No standard payload is stated for these drawing-defined structures. Supply the required loads and mounting conditions. Design approval and any structural verification must be assigned and agreed for the actual equipment.
What should the chassis RFQ include?
Provide the assembly and component drawings, CAD files, material and finish, load inputs, mounting datums, relevant module references, hardware BOM, inspection conditions and delivery format.
Can you supply the outer covers as well?
Cover and housing components can be included as a separately defined part of the mechanical scope. Identify shared interfaces and the assembly acceptance criteria so the two scopes do not overlap or leave gaps.
Does chassis fabrication establish medical-device approval?
No. Applicable certification documents and project support can be discussed during RFQ, but manufacturing the metal structure does not itself approve a finished device. The responsible OEM retains final device design and regulatory validation.
