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/.

⚡ Direct Answer: What Are Sheet Metal Enclosures for OEM Equipment?

Sheet metal enclosures for OEM equipment are drawing-defined mechanical protective housings custom-manufactured to shield internal electronics, power modules, PLCs, and pneumatic valves across industrial automation, medical diagnostic, telecommunications, and energy storage systems. Unlike off-the-shelf standard boxes, custom OEM enclosures integrate application-specific display bezels, custom connector gland plates, internal DIN rail sub-racks, continuous polyurethane foam gaskets (IP54/IP65/NEMA 4), and corporate brand powder coating cured to ASTM B117 salt spray standards.

OEM Equipment Enclosure Comparison: Custom vs. Catalog Box

Comparison Parameter	Catalog Off-the-Shelf Enclosure	MSTFAB Custom OEM Sheet Metal Enclosure
HMI & Connector Cutouts	Manual drilling/punching on finished painted metal creates rust points.	100% pre-cut on 15kW fiber lasers prior to powder coating (±0.1 mmmm accuracy).
Internal Space Efficiency	Bulky standard envelope wastes internal volume and increases machine footprint.	Engineered around internal component CAD models with integrated wire management.
Branding & Aesthetics	Generic industrial beige/grey paint with stick-on badges.	Exact RAL/Pantone color matching, laser-cut backlit logo recesses, dual-tone finishes.
