Free DFM review

Engineered to save, built to perform.

Every quote request gets a free one-on-one engineering review, whether your part is machined, cast, printed, molded or finished. Before anything is cut, poured or coated, we flag what can't be made as drawn, check the process suits your quantity and call out what drives cost.

VH-2207Valve housing, CNC milled and anodized

Drawing received

Five findings on one drawing. The example is a CNC-milled, anodized housing; cast, printed and molded parts get the same markup. Select a finding to zoom in, then accept the change or keep it as drawn.

      Design rules

      Six rules behind most of the savings

      These six checks find most of the cost on a typical drawing. The sketches show machining and casting; the rule of thumb under each one covers what changes for printed, molded and finished parts. Move the slider to see where each rule starts to bite.

        What the review changed on real parts

        Four recent reviews, one from each process we run: CNC machining, rapid casting, polymers and surface finishing. Open one to see what changed, and what the customer chose to keep.

        • As submitted

          • R0.5 inside corners on a 14 mm deep pocket
          • 3.7 mm slot, no standard cutter
          • Ra 0.8 on every face

          After review

          • R2 corners, cut with a Ø4 end mill
          • 4.0 mm slot, one pass
          • Ra 0.8 on the jaw face only

          Customer kept

          • The 0.2 mm chamfer on the jaw tip, needed for grip

        • As submitted

          • No draft on the outside walls
          • Walls from 1.6 to 5 mm, prone to porosity
          • Parting line across a cosmetic face

          After review

          • 1.5° outside, 2° on the cores
          • 2.5 mm walls with cored-out bosses
          • Parting line hidden under the lid edge

          Customer kept

          • Embossed logo on the top face, with a slide in the die

        • As submitted

          • Each shell machined from solid ABS
          • Walls from 1.2 to 4 mm
          • Self-tapping screws into plain bosses

          After review

          • One SLA master, silicone molds, cast in ABS-like PU
          • 2 mm walls, ribs at 60% of the wall
          • M3 brass inserts cast into the bosses

          Customer kept

          • Fine grip texture, put on the master so every casting copies it

        • As submitted

          • Hand polish and black anodize on all six faces
          • Ø10 H7 bore and M3 threads anodized with the rest
          • No face marked for rack contact

          After review

          • Front face brushed as the cosmetic surface, the rest bead-blasted
          • Bore and threads plugged, so they stay to size
          • Rack contacts inside two mounting holes

        Questions

        Before you upload

        Still unsure? Write to [email protected] and an engineer will answer, not a bot.

        • Yes. Every quote request gets one, whether or not you order, from a single prototype upward. It's how we avoid surprises once material has been cut, poured or printed.

        • All four we run: CNC machining, rapid casting (sand, investment and die casting), 3D printing and polymers (SLA, SLS, vacuum casting, LSR) and surface finishing. If your part would be cheaper or faster by another route at your quantity, the report says so.

        • No. We mark suggestions on your drawing and quote both versions. We only make what you approve in writing, and the approved drawing is attached to your order.

        • Then keep it. We'll tell you what it costs and the best way to make it, such as EDM for sharp corners or CMM checks on just the critical bore, and quote it as drawn.

        • A 3D model (STEP, IGES, Parasolid or SolidWorks) plus a 2D drawing in PDF or DWG with tolerances, threads and finishes. A model alone works too; we'll ask which dimensions are critical. If you haven't settled on a process, tell us the quantity and what the part does, and we'll recommend one.

        • A manufacturing engineer who knows the process your part will be made by. When a part crosses processes, say a casting that is machined and then anodized, one engineer still owns the whole route and stays on your project through production and delivery, so nothing gets lost in a handover.

        • We sign your NDA or ours before you upload. Files are stored encrypted, every access is logged, and only the assigned engineer and quality team can open them.
