Custom OEM supply to your drawings
REALJET provides custom sheet metal cases to your drawings for OEM and contract manufacturing orders. We review body-to-cover seams, access openings and mounting provisions before confirming the custom manufacturing scope. The manufacturing definition starts with the part's function, its installation space and the components it connects to. We review the requested geometry and delivery condition against those interfaces before defining the supply scope.
For this application, the drawing review focuses on body-to-cover seams, access openings and mounting provisions. Define whether the order covers a bare shell or an assembled case with hardware. A photograph provides a configuration example; your approved documentation defines the material, dimensions, performance requirements and acceptance criteria for the ordered component.
Application fit
Body-to-cover seams, access openings and mounting provisions are reviewed against the equipment arrangement.
Material selection
Review specified sheet steel, stainless steel or aluminum against the design, process route and required delivery condition.
Acceptance focus
Define whether the order covers a bare shell or an assembled case with hardware.
Project specification and quotation inputs
| Item | Information to confirm |
|---|---|
| Component / service | Custom Sheet Metal Cases |
| Material options | Specified sheet steel, stainless steel or aluminum |
| Geometry and interfaces | Body-to-cover seams, access openings and mounting provisions |
| Production scope | Box and case fabrication with agreed secondary operations |
| Inspection focus | Lid seating, corner condition and hardware access |
| Quantity | Prototype, pilot batch or repeat order quantity for review |
| Supply condition | Loose component, part set or assembly as specified |
| Delivery | Schedule, destination and packing confirmed with the quotation |
Working size, thickness, tolerances and lead time depend on the approved design, material, quantity and inspection scope. Identify critical features and the applicable measurement conditions on the drawing so the quotation can confirm a practical acceptance basis.
What is sheet metal fabrication for this application?
A fabricated box uses formed or joined panels to create an internal volume with a defined cover or opening. A useful specification describes both the external envelope and the space left after flanges, seams and hardware are installed.
For this product, the process is applied to provide a formed case around controls or mechanical equipment. The particular review priorities are body-to-cover seams, access openings and mounting provisions; those details connect the manufacturing steps to the equipment's assembly requirements.
REALJET manufacturing advantages for this application
Review before release
The drawing revision, component function and mating interfaces establish a shared manufacturing reference before production begins.
Process matched to the part
The body, lid and fixing details are coordinated to preserve usable space and allow assembly with the selected hardware.
Clear acceptance points
Inspection scope focuses on lid seating, corner condition and hardware access, together with the critical characteristics identified by the buyer.
Controlled repeat supply
Approved samples, material choices and drawing changes are recorded against the part number so subsequent orders can refer to the same release condition.
Fabrication technology and production sequence
- Define internal and external dimensions.
- Cut and form the body and cover.
- Join corners and prepare mounting positions.
- Apply the finish and install agreed fittings.
- Check closure, envelope and accessible space.
The final route is selected during technical review. Additional operations, purchased fittings and testing are included only where agreed in the order scope. Identify whether the requested supply is a shell, a body-and-cover set or a complete box assembly.
Materials, finish and delivered condition
Material selection for custom sheet metal cases can include specified sheet steel, stainless steel or aluminum. The choice must reflect the actual application, rather than relying on the appearance or colour of the example image.
Review coating, plating or a bare-metal finish against the specified material and environment. Identify appearance zones, threads, grounding contacts and fitted surfaces before defining masking and finishing requirements.
Inspection and quality documentation
Define whether the order covers a bare shell or an assembled case with hardware. The inspection plan should address lid seating, corner condition and hardware access, with critical dimensions and test methods identified before production release.
Agree whether the order requires material identification records, dimensional reports, sample approval or additional tests. Any specified certification, qualification or compliance evidence is reviewed for the actual supply scope before order acceptance. Packaging should protect finished surfaces and the geometric features used to install the part.

Questions about custom sheet metal cases
What should I show on the drawing?
Identify body-to-cover seams, access openings and mounting provisions, together with the part number, revision and mating references. Provide a dimensioned PDF and available STEP, DXF or DWG files as appropriate to the component. Identify whether the requested supply is a shell, a body-and-cover set or a complete box assembly.
Which material and finish should I request?
Start with specified sheet steel, stainless steel or aluminum. Describe the operating environment and identify any functional or visible surfaces. The material, manufacturing route and finish are reviewed together before the quotation is finalized.
What needs particular attention on this project?
Define whether the order covers a bare shell or an assembled case with hardware. State the acceptance method for any critical characteristic, and confirm whether the order includes only the component or additional hardware and assembly operations.
Can I order an initial sample before repeat production?
A prototype or pilot batch can be reviewed against the design and requested quantity. Agree sample acceptance, any required test evidence and the revision to be used for the subsequent order. Lead time is confirmed after the scope and material availability are checked.
