Mechanical Design, Tolerance Stack-Up & DFMA Consulting
Cut component part counts, prevent costly injection mold tooling rework, and validate production tolerances before cutting metal. Backed by verified Dassault Systèmes CSWE-Design certification and 8+ years of hardware engineering.
Design for Manufacture & Assembly (DFMA) Competence
Bridging theoretical mechanics with practical manufacturing economics across plastics, sheet metal, and machined parts.
Boothroyd-Dewhurst DFA Part Consolidation
Systematically challenge every component using the three theoretical minimum part-count questions (relative motion, distinct material, service disassembly) to reduce assembly time and eliminate hardware.
Injection Molding & Tooling DFM Reviews
Pre-tooling design reviews verifying nominal wall uniformity, rib-to-wall ratios (0.5–0.6t), draft angles per SPI/VDI texture standards, coring depth, and side-action elimination via pass-through shut-offs.
Precision Sheet Metal Forming & K-Factor Math
First-principles calculation of bend allowance, bend deduction, and outside setback. Calibration of K-factor from press-brake test coupons to guarantee first-pass flat-pattern laser accuracy.
1D & 3D Tolerance Stack-Up Analysis
Rigorous vector-loop tolerance analysis comparing Worst-Case (WC), Root Sum Square (RSS), and Cpk-adjusted statistical methods to prevent shop-floor interference while avoiding over-tolerancing costs.
The 4-Step Design Verification Framework
How we audit, optimize, and validate your CAD models prior to tooling purchase orders.
Evaluate existing assembly CAD, identify failure modes, and define critical datum reference frames.
Score assembly efficiency, identify redundant fasteners, and consolidate adjacent parts.
Verify wall thicknesses, draft angles, bend radii, and tool access across fabrication methods.
Deliver 100% ASME Y14.5-2018 compliant 2D drawings with unambiguous GD&T callouts.
International Standards Compliance
ASME Y14.5-2018 GD&T
Unambiguous geometric dimensioning, datum reference frame definition, and bonus tolerance MMC/LMC verification.
ISO 286 Limits & Fits
Precision hole-basis and shaft-basis tolerance calculations (H7/g6, H7/h6, H7/p6) for reliable bearing and bushing press fits.
ASME B36.10M / B36.19M
Piping schedule dimensions, wall thicknesses, and hydrostatic burst pressure compliance calculations.
