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 Is the Scope of Sheet Metal Contract Manufacturing for OEMs?

Turnkey sheet metal contract manufacturing for OEM products encompasses end-to-end industrial product execution across 5 integrated operational scopes: 1) Full-Process Fabrication: Precision fiber laser cutting, multi-axis CNC press brake bending, robotic/manual seam welding, and automated PEM clinch fastener insertion; 2) Turnkey Box-Build Mechanical Assembly: Installing hinges, latches, gas springs, slide rails, cable glands, and door seals prior to shipping; 3) Quality Assurance & Agency Compliance: Delivering AS9102-style FAI reports, Cpk capability data, UL 508A grounding continuity tests, and ISO 9001 traceability; 4) Supply Chain & BOM Kitting: Managing hundreds of hardware and subassembly SKUs under single top-level OEM part numbers; and 5) Global Export Logistics: Certified ISPM-15 export crating, DDP/FOB ocean freight management, and customs clearance support.

Sheet Metal Contract Manufacturing Scope of Work

Manufacturing Scope	Basic Job Shop Scope	MSTFAB Turnkey Contract Manufacturing
1. Engineering & DFM	Cuts directly from drawings; ignores assembly conflicts	Full 3D CAD DFM review, bend simulation, tolerance stack-up analysis.
2. Mechanical Assembly	Ships loose, knocked-down parts in cartons	Complete mechanical box-build: hinges, latches, gaskets, trial-fitted doors.
3. Quality Agreements (QAA)	Standard commercial warranty only; no formal FAI	Binding Quality Assurance Agreement, AS9102 FAI, CMM logs, MTR certs.
4. Inventory & Repeat Orders	Quotes order-by-order with volatile lead times	Blanket PO contracts, safety buffer stock, guaranteed 5–7 day release lead times.

Industrial equipment OEMs and technology startups choose contract manufacturing to focus internal resources on core software, controls, and market distribution, while outsourcing heavy metalworking capital equipment and production labor. A true contract manufacturing partnership goes far beyond cut-and-bend job shop tasks: it requires institutional accountability for part fit, functional finish durability, and reliable repeat production deliveries. MSTFAB acts as a seamless extension of your engineering and manufacturing operations.

Frequently Asked Questions on Sheet Metal Contract Manufacturing

What is a Quality Assurance Agreement (QAA) in contract manufacturing?

A QAA is a legally binding annex that defines inspection standards, defect classifications, sampling plans (AQL levels), warranty terms, and corrective action timeframes between the OEM and contract manufacturer.

Can MSTFAB manage OEM-specified sub-tier component suppliers?

Yes. We regularly procure OEM-directed specialty components—such as locks, handles, EMC gaskets, cable glands, and cooling fans—and integrate them into the finished mechanical subassembly under single-point warranty.
