What does MSTFAB manufacture?

MSTFAB is the international brand of Guangzhou Maisituo Sheet Metal Manufacturing Co., Ltd. It makes drawing-defined sheet metal parts and empty mechanical enclosure shells for OEM buyers, using laser cutting, CNC bending, welding and mechanical assembly. Surface treatments such as powder coating may be coordinated with external partners depending on the order.

Which materials does MSTFAB work with?

Common options include carbon steel, galvanized steel, stainless steel and aluminum. Grade, thickness, dimensions, critical tolerances, hardware, finish and inspection criteria are specified per project on the approved drawing.

What are the MOQ and lead time for custom sheet metal parts?

There is no single MOQ or lead time that applies to every part. MOQ, price, achievable tolerances, lead time, finishing route and inspection deliverables are confirmed in the project quotation and purchase order after the drawing is reviewed.

Does MSTFAB supply electrical components or certified finished equipment?

No. The normal supply scope is fabricated metalwork and empty mechanical housings. Electrical components, wiring, software, system integration and final equipment certification remain with the buyer unless a written quotation or contract explicitly includes them.

How do I request a quote?

Send STEP, STP, DXF, DWG or PDF files with the drawing revision, material and thickness, quantity, critical dimensions, hardware, finish, inspection needs and delivery destination through the RFQ page at https://mstfab.com/contact/.

Custom Electrical Control Enclosure Fabrication for Compact OEM Panels reference manufactured from customer drawings by MSTFAB

Not every electrical enclosure is a floor-standing cabinet. Many OEM projects need compact control housings, operator boxes or equipment-mounted enclosures. These parts look simple until the connector cutout is 2 mm off and everyone suddenly becomes very interested in tolerances.

This page is for smaller electrical control enclosures and housings, not large control cabinets or broad metal cabinet procurement.

Need production capability? This article focuses on compact control enclosure layout and access checklist. For manufacturing scope, process capability and drawing-based quotation support, review MSTFAB’s control cabinet enclosure fabrication.

What OEM buyers should check first

Control cutout positions for switches, screens, connectors and cable glands.
Use realistic bend radii and flange lengths so small boxes close properly.
Plan PEM inserts, studs or threaded bosses before coating.
Define grounding points and masked areas if electrical contact is required.
Check lid fit, gasket seating and screw access during prototype review.

Decision table

Decision area	What buyers should check
Operator boxes	Need accurate HMI openings and comfortable service access.
Terminal housings	Need cable entry and grounding details.
Equipment-mounted panels	Need vibration-resistant hardware and clean mounting.
Control covers	Need cosmetic finish and repeatable screw alignment.

Manufacturing route at MSTFAB

For drawing-based programs, MSTFAB reviews the part requirement before quoting so the manufacturing route matches the real use case. A typical route includes small enclosure DFM review, laser cutting, CNC bending, PEM hardware installation, surface finishing, fit check. The goal is not to make the quote look heroic; the goal is to make the delivered parts fit, finish and assemble correctly.

Evidence buyers can request

For quality-sensitive OEM projects, buyers can request sample photos, production-process confirmation, finish notes, packaging photos or dimensional checks for critical features. This is especially useful when the part includes mating holes, doors, hinges, cable openings, visible surfaces or welded structures.

FAQ

Are compact enclosures harder to bend?

They can be, because short flanges and nearby holes leave less room for tooling.

Should threaded hardware be added before coating?

Usually yes, unless masking or post-finish installation is specified.
