Can We Build Your Enclosure or Casing?
These are practical industry-range guidelines for early project screening, not universal guarantees. Final capability, tolerance and price follow the drawing, material, geometry and quantity review.
Mild steel, galvanized steel, stainless steel 304/316 and aluminum
Selected according to material, enclosure structure and project requirements.
Built to customer drawings, equipment dimensions and installation requirements.
Reviewed around doors, mating parts, hardware, openings and assembly interfaces.
One production-intent sample, pilot quantities and repeat production
STEP / STP, DXF / DWG and PDF files accepted for review
Powder coating, wet paint, plating, anodizing, brushing, polishing and specified masking
Inserts, studs, hinges, rails, seals, brackets, panels and specified hardware
Need a tighter tolerance, thicker structure or larger body? Mark the critical features on the drawing and we will review the route instead of rejecting the project from a generic table.
Five Enclosure Details We Check Before They Become Rework
Door & Panel Alignment
Door gaps, panel position and closing interfaces are checked against assembly requirements.
Hole & Cutout Position
Holes, ventilation cutouts and connector openings are checked against approved drawings.
Edges & Openings
Cut edges, openings and fabricated features are checked before finishing and assembly.
Critical Contact & Masking Areas
Grounding, contact and masking areas are controlled according to project requirements.
Surface Protection Before Shipment
Finished surfaces are checked and protected before packing to reduce handling damage.
Three Finished Products. Three Different Assembly Risks.
The photographs below are Yishang-manufactured customer projects. Customer names and proprietary dimensions remain private.
OEM Equipment Kiosk Enclosure
OEM equipment manufacturer · Customer name confidential
Powder-coated sheet-metal body · Framed trim · Doors, fasteners and silkscreen
Keep the tall body visually clean while protecting access-door fit, deburred handling edges and accurate control-panel graphics.
We reviewed access-door interfaces, edge finishing, fastener positions and silkscreen locations as one assembly.
The finished enclosure combined formed panels, service access, installed details and durable graphics in one assembly-ready body.
Custom Chassis enclosure
Electrical equipment manufacturer · Customer name confidential
Powder-coated steel · Hinged doors · Ventilation and raised base details
Repeat the door, hinge, ventilation and base relationships consistently across a production batch.
We kept the approved hinge, ventilation and raised-base relationships consistent through production and inspection.
A repeatable cabinet configuration was delivered with consistent visible finish and installation-related details. No unverified IP rating is claimed.
Compact Electronics Enclosure
Electronics equipment buyer · Customer name confidential
Formed steel panels · Powder coating · Vent cutouts, rivets and removable cover
Control hole edges, panel straightness, rivet alignment and coating appearance around dense ventilation features.
We controlled deburring, panel flatness, rivet positioning and surface preparation around the dense openings.
The finished chassis was prepared for downstream component and hardware installation without leaving burr and finish correction to the customer.
Not Sure Whether the Current Drawing Is Production-Ready?

Questions Before You Send an RFQ.
What is the MOQ?
One production-intent sample can be made first. Production MOQ is reviewed around enclosure size, tooling, finish, purchased hardware and repeat demand rather than one fixed number.
How quickly will I receive a quotation?
We respond within 24 hours with initial feedback or clarification questions. A formal quotation follows once the manufacturing scope is clear.
Can I request a quote without complete drawings?
Yes. Early-stage drawings, marked-up PDFs, sketches, reference photos and samples can start the review. We will identify the missing details that affect fit, finish and quotation.
Can you sign an NDA?
Yes. An NDA can be arranged before detailed drawings and confidential project information are reviewed.
Which files can I send?
STEP or STP, DXF or DWG and PDF are preferred. Photos, marked-up sketches and physical samples can support an early review.
Can you meet tighter tolerances?
Often yes on selected critical features. Mark the functional dimensions and datums so the route can be reviewed around material, size, forming, welding and inspection.
Do you install hardware and assemble related parts?
Yes, when included in scope. Inserts, studs, hinges, rails, seals, brackets, panels and specified hardware can be coordinated with the enclosure.
Do you supply standard or semi-standard enclosures?
Yes. Standard-style, semi-standard and fully custom B2B enclosure projects can all be reviewed when the specifications and order requirements are clear.
Do these enclosures automatically have an IP, NEMA or UL rating?
No. A rating is only stated when the design, components, production controls and required testing or certification have been agreed for that project.
Send Your Enclosure Project Before Production Problems Reach Assembly
