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 a DFM Review for Laser Cutting?

A DFM (Design for Manufacturability) review for laser cutting is a systematic CAD drawing evaluation conducted prior to production to ensure part features align with laser beam physics. Key rules include maintaining minimum hole diameters equal to or greater than material thickness (D ≥ 1.0T), maintaining minimum distance between cutouts and sheet boundaries (d ≥ 1.5T), and applying corner radii to eliminate thermal burnout and localized stress concentration.

Essential DFM Engineering Rules for Fiber Laser Cutting

Design Feature	Recommended DFM Rule	Manufacturing Risk If Ignored
Minimum Hole Diameter	D ≥ 1.0T (Carbon Steel/SS); D ≥ 1.2T (Aluminum)	Beam pierce spatter damages optical nozzle; tapered or out-of-round holes.
Hole-to-Edge Distance	Distance d ≥ 1.5T from outer part boundary	Thermal distortion causes edge bulging and perimeter blowout.
Hole-to-Bend Relief	Distance L ≥ 2.5T + R_bend from bend tangent	Tension stretching deforms circular holes into ovals during brake bending.
Slot Width & Web Spacing	Minimum slot width ≥ 1.0T; Web thickness between slots ≥ 1.5T	Excess heat causes micro-bridges to melt, warp, or bridge adjacent cuts.

Frequently Asked Questions on Laser DFM

What happens if a laser-cut hole diameter is smaller than the sheet thickness?

When D < 1.0T, the laser pierce dwell time generates excessive heat that cannot dissipate, causing cratering, nozzle blowouts, and tapered holes. For holes smaller than sheet thickness, MSTFAB laser-marks center pilot points and secondary CNC drills to nominal diameter.
