PLC Enclosure RFQ Checklist: Cutouts, Rails and Hardware Fit
MSTFAB manufactures the sheet metal enclosure shell, not a complete PLC control system. This page helps buyers define cutouts, rails, mounting plates and hardware fit before sending the RFQ. Buyer checks include Separate metal enclosure scope from electrical assembly scope., Mark cable entries, DIN rail positions and mounting plate holes., Confirm door gap, hinge, lock and gasket requirements.
Can You Get a Sheet Metal Quote Without a 2D Drawing?
Can you request a sheet metal quote without a 2D drawing? Compare STEP-only models, sketches and samples, identify missing specifications, and separate a budget estimate from production approval.
Can I Send a STEP File?
The PDF Limitation A 2D PDF drawing is legally binding, but geometrically blind. It tells the factory what the final part should look like, but it fails to prove whether the part can actually be manufactured. For complex OEM assemblies, an isolated PDF forces the factory into a cycle of reverse-engineering and blind assumptions, destroying […]
Sheet Metal DFM Checklist: 8 Checks Before Release
Use eight sheet metal DFM checks for material, bends, tolerances, hardware, welds, finish, assembly and inspection before releasing production files.
Why We Protect OEM Case Studies
The Red Flag of Manufacturing If a sheet metal supplier sends you a competitor’s highly detailed CAD files or proprietary enclosure blueprint within five minutes of an RFQ to “prove their capability,” do not be impressed. Be terrified. Because tomorrow, they will use your engineering IP to impress someone else. Why We Do Not Expose […]
Sheet Metal Fabrication Capability Checklist for OEM Buyers
Verify sheet metal fabrication capability by connecting each drawing feature to a process route, risk, inspection method, owner and production evidence.
What Drawings Are Needed for Sheet Metal Fabrication?
Quick Answer To eliminate procurement guesswork, prevent supply chain delays, and guarantee an accurate cost structure, an OEM sheet metal fabrication RFQ must include two non-negotiable files: a native 3D STEP file (for geometry) and a 2D PDF drawing (for tolerances, materials, and finishing requirements). Unambiguous Drawings Drive Predictable Supply Chains A predictable sheet metal […]
Sheet Metal Curling Process: Design Rules, Tooling & DFM Guide
Sheet Metal Curling Process: Design Rules, Tooling & DFM Guide Blood on the Assembly Floor is Bad for OPEX Let’s be brutally honest about raw, unformed sheet metal: it is essentially a giant, floppy razor blade. If you are engineering a heavy-duty industrial cabinet, a food-grade hopper, or an outdoor telecom enclosure, and you leave […]
