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/.

Contract Sheet Metal Fabrication Manufacturer for OEM Industrial Projects

Developing industrial equipment requires more than a supplier that can simply cut and bend metal. OEM manufacturers need a contract sheet metal fabrication partner capable of managing production from engineering drawings to repeat manufacturing while maintaining quality, delivery schedules, and production consistency.

At MSTFAB, we specialize in contract sheet metal fabrication for OEM industrial projects, supporting equipment manufacturers, automation companies, medical device manufacturers, telecommunications suppliers, battery system integrators, HVAC manufacturers, and renewable energy companies.

We manufacture according to your approved drawings while providing engineering support throughout production. Our services include laser cutting, CNC bending, welding, machining, PEM hardware installation, surface finishing, assembly, and inspection.

For complete build-to-print metal manufacturing, visit our build-to-print sheet metal manufacturer hub. For multi-process capabilities, check out our integrated laser cutting bending welding assembly supplier page.

What Is Contract Sheet Metal Fabrication?

Contract sheet metal fabrication means outsourcing the manufacturing of custom sheet metal parts and assemblies to a specialized fabrication partner while your engineering team retains ownership of the product design and intellectual property.

Unlike standard job-shop manufacturing, contract fabrication focuses on long-term partnerships, repeatable quality, and continuous process improvements. We offer engineering reviews to improve manufacturability. Visit our DFM for sheet metal fabrication page to learn more.

Purchasing Challenges for OEM Industrial Projects

Challenge 1 – Managing Too Many Suppliers

Outsourcing laser cutting, bending, welding, powder coating, and assembly to different vendors creates communication delays, quality variation, and high logistics costs. MSTFAB offers a one-stop fabrication system to manage these processes under a single quality system.

Challenge 2 – Prototype Quality Does Not Match Production

Producing a single prototype is different from maintaining consistent batch quality. Inconsistent bend angles, hole variations, or weld distortion can halt your assembly line. We support prototype-to-production transitions. Read more on our sheet metal prototype to batch production supplier page, or check out our sheet metal manufacturer for repeatable production quality details.

Challenge 3 – Engineering Changes During Production

Industrial projects often require drawing revisions. We maintain strict revision control so that production follows the latest approved documentation. If you supply CAD files, read our sheet metal parts manufacturer from CAD drawings page.

Challenge 4 – Production Delivery Delays

Late delivery delays equipment assembly and project completion. Our production planning focuses on reliable delivery performance. For long-term production, visit our custom sheet metal production run manufacturer page.

Our OEM Contract Manufacturing Process

Every project starts with a detailed engineering DFM review. Once materials are verified, we utilize high-precision fiber laser cutting, CNC press brake bending, welding, machining, PEM hardware installation, surface finishing, and mechanical assembly.

For hardware insertion details, visit our sheet metal fabrication with PEM hardware installation page.
For cabinet assembly details, visit our custom sheet metal enclosure fabrication page.

Quality Control for Contract Manufacturing

Our quality management is integrated throughout the process. We verify incoming sheets (IQC), inspect first articles (FAI), monitor critical features during production (IPQC), and conduct final checks (FQC). To learn more about our material checks, visit our metal fabrication supplier with incoming material inspection page.

Materials & OEM Applications

We process carbon steel, cold rolled steel, galvanized steel, stainless steel (304/316), and aluminum. These components support industrial automation, telecommunications, energy storage systems, medical equipment, and HVAC systems.
