MSTFAB Factory Photos: Sheet Metal Production and QC
MSTFAB, the international brand of Guangzhou Maisituo Sheet Metal Manufacturing Co., Ltd., shares sheet metal process visuals to help OEM buyers ask better questions about fabrication, inspection and export packing. Some scenes are illustrative; request current, site-specific evidence before treating an image as proof of a particular machine, worker or production order.

Inspection points buyers can verify
Export packing for overseas buyers
Workshop areas buyers should check before an RFQ
What a gallery can and cannot prove: These visuals show the processes and checks to discuss. They do not independently verify which facility, employee or machine will handle your order. Ask for current workshop photos or a live walkthrough, a planned production route, an inspection record tied to your drawing and the scope of any finishing partner.
Use this gallery with our process videos and inspection record guide to define the evidence your project requires.
Fiber Laser Cutting Workshop
Check nesting, cut edges, ventilation openings and part identification before forming. Review our laser cutting services for process scope and RFQ requirements.
CNC Press Brake Bending
Press brake setup and bend sequence affect door gaps, flange fit and tolerance stack-up. See our sheet metal bending capability.
Finish Masking & Interface Protection
Specify masking for threaded holes, grounding contacts and gasket lands in the approved drawing. Selected finishing processes may be completed by qualified long-term partners; review the surface treatment scope before quotation.
TIG & MIG Welding Area
Fixture control, heat input and weld finishing influence strength and assembly fit. Explore MSTFAB welding services.
Photos that answer buyer questions before a PO.
These photos focus on the moments a quotation cannot prove by itself: first-article measurement, drawing review, cabinet fit-up, finished surfaces, subassembly checks and whether production-ready parts are handled like buyer property, not random workshop leftovers.
First Article Inspection
Critical holes, cutouts and fit dimensions are checked against the released drawing before repeat production. This is where small drawing mistakes get caught before they become a full batch problem.
Inspection Record Review
Measurement records and buyer-defined checkpoints help confirm the supplier is not relying on ‘looks fine’ as a quality system.
Drawing & Production Review
Engineering, production and QC teams align material, tolerance, finish, hardware and assembly risks before release, so procurement does not become emergency repair later.
Sheet Metal Enclosure Fabrication
Empty cabinet shells and housings checked for bend accuracy, weld quality, door gaps and mounting features before finishing. See our custom sheet metal enclosure fabrication capability.
Finished Stainless Cabinets
Visible surfaces, weld cleanup and protected handling reviewed for custom sheet metal enclosure fabrication.
Cable Management Fabrication
CNC-formed channels and routing parts prepared for network cabinet fabrication and telecom projects.
From RFQ to shipment: checkpoints that reduce sourcing risk.
The point is not to count machines. It is to see whether one released drawing can move through cutting, forming, welding, finishing, inspection and protected shipment without losing the details that make your assembly work.
01 / Drawing & DFM review
STEP and PDF files reviewed for material, bend access, hardware clearance, tolerances and finish risks. Start with our sheet metal fabrication overview.
02 / Laser cutting
Panels, slots, vents and enclosure blanks are cut with downstream bending, part marking and revision control in mind.
03 / CNC bending
Flanges and returns are formed in a planned sequence to control angle variation, door fit and assembly stack-up.
04 / Welding & fit-up
Frames and enclosures fixtured, welded and checked before finishing and assembly and packaging.
05 / Finish & inspection
Check masking, coating appearance and dimensions against the approved specification before packing. Confirm whether the selected finish is completed by MSTFAB or a qualified long-term partner for that order.
06 / Export packing
Protective film, foam, corner guards, pallets or crates selected for the part size, finish and shipping route.
A practical supplier checklist before releasing a PO.
Use this table to turn workshop photos into useful supplier questions. Ask what is controlled, what can be documented and where your drawing requirements enter the production route.

Machine condition, edge quality, part nesting and cut consistency
Electrical panels, brackets, telecom cabinet blanks
CNC bending area
Tooling setup, bend route, angle control and flange consistency
Enclosure doors, gasket returns, channels and mounting rails
Welding / finishing
Weld seams, fixture control, grinding, surface preparation
Outdoor cabinets, machinery guards, stainless assemblies
Inspection area
First article checks, drawing review, caliper/CMM inspection records
Critical fit-up, export acceptance and repeat orders
Assembly / packing
Hardware insertion, cabinet fit-up, protective packaging
OEM programs shipped to USA, Europe and Australia
Factory evidence should make procurement easier, not just prettier
MSTFAB supports overseas OEM teams with factory-direct engineering communication, first-article checks, production-stage photos and export packing review. The useful question is not simply, “Do you have a factory?” It is, “Can you show how my drawing is controlled from RFQ to shipment?” That evidence helps buyers approve a supplier with fewer assumptions.
Factory history
23+ years supporting precision sheet metal parts, enclosures and cabinet projects.
In-house route
Laser cutting, CNC bending, welding, finishing, inspection and assembly coordinated under one production system.
Documented checks
ISO 9001 quality workflow with drawing-based checkpoints and inspection records available by project requirement.
Export communication
Drawing review, project updates and protected packing support for buyers in the USA, Europe and Australia.
Buyer questions before sending drawings or deposits.
Short answers for procurement teams that want fewer surprises before a sample, deposit or batch order.
Can overseas buyers request production photos before placing an order?
Which factory areas are shown on this page?
What should buyers verify beyond the photos?
Can MSTFAB support a video factory inspection?
What types of projects are made in the factory?
Know who handles each step.
A factory photo is useful. A quotation that names the route for your enclosure drawing is better. Confirm the process owner and acceptance checks before you approve the order.
- 01
Metalwork and fit
MSTFAB plans drawing review, cutting, bending, welding, enclosure fit and inspection against the approved revision.
- 02
Selected finishing
Powder coating or other specified finishes may be performed by long-term partners. Confirm the route, masking and acceptance checks in the quotation.
- 03
Final product boundary
These photos do not certify a finished EV charger, telecom device or medical product. Electrical build and final-product approval depend on the OEM's agreed scope.
