Our Process
How It Works
From your design to delivered parts — a clear, controlled process with inspection gates at every stage and full documentation on delivery.
Upload Your Design
Send STEP, IGES, Parasolid, or SolidWorks files with your requirements. We accept files up to 100MB per upload. Include 2D PDF drawings if available — it speeds up quoting significantly.
Accepted formats: STEP, IGES, XT, SolidWorks, Pro/E, Inventor. Drawings: PDF, DWG.
DFM Review & Quote
Our engineers review manufacturability — checking wall thickness, tolerance stack-ups, feature accessibility, and material suitability. You get a detailed quote within 24 hours with DFM notes included, not just a price.
Every quote includes: unit price, tooling cost (if applicable), lead time, DFM observations, and recommended alternatives.
Production
CNC machining, mold making, or EDM — executed to spec with in-process inspection at setup, mid-run, and completion. Program verification and first-off approval before production begins.
In-process checks: setup verification, mid-run SPC sampling, and final dimensional audit on every run.
Quality Validation
CMM inspection with full dimensional reports on all critical features. First Article Inspection (AS9102-compliant) for new parts. Nothing ships without documented proof of conformance.
Standard: CMM report on critical dims. FAI available on request. PPAP Levels 1–4 for automotive. Full inspection data retained for 7 years.
Delivery & Documentation
Parts arrive with full documentation — CMM inspection reports, material certifications (mill test reports), certificates of conformance, and full traceability. International shipping via DHL/FedEx/UPS.
Standard package: inspection report, material cert, CoC, packing list. Expedited and consolidated shipping available.
Design Support
Design for Manufacturing
Better parts start with better design decisions. We catch issues before they become costly problems — and we back it with specific examples, not vague advice.
Wall Thickness, Draft Angles & Fillets
Recommendations for optimal geometry that machines cleanly and molds reliably. We catch thin walls that cause fill issues, missing drafts that increase ejection force, and sharp corners that concentrate stress.
Example: A 0.8mm wall in PA66-GF30 will warp during ejection. We recommend 1.2mm minimum with 1° draft per side — before tooling starts.
Material Selection Guidance
Based on function and cost — we help you pick the right grade, not just the most expensive one. Aluminum 6061 vs 7075, PEEK vs PEI, SS316 vs SS303 — the right choice depends on load, environment, and machinability.
Example: 7075-T6 costs 40% more than 6061-T6 but offers 2x the tensile strength — unnecessary for non-structural brackets.
Tolerance Optimization
We flag over-specified dims that drive cost without adding value — and tighten what actually matters. A blanket ±0.01mm on every feature can double your part cost. We identify which features need precision and which can be opened up safely.
Example: Opening non-mating faces from ±0.01mm to ±0.05mm typically reduces machining cost by 25-35% with zero functional impact.
Feature Accessibility Review
Machining and molding feature checks to ensure tool access and clean release. Undercuts, deep pockets, and tight radii that require special tooling or EDM are flagged early — with alternatives.
Example: A 2mm radius in a 30mm deep pocket requires a long-reach tool with high deflection risk. We recommend 3mm minimum or add a tool access slot.
Cost & Lead Time Reduction
Early DFM feedback reduces iterations, lead time, and unit cost by 15–40%. Every design revision after tooling starts costs 5-10x more than catching it during the review phase. Our DFM process eliminates that waste.
Typical savings: 15-40% unit cost reduction, 30% fewer revisions, 1-2 weeks shorter development cycle.
Risk Identification
We identify critical-to-quality (CTQ) features early and recommend inspection strategies. Features with high scrap risk — thin walls, tight position tolerances, small threads — get flagged with mitigation options before production.
Example: M2 threads in stainless steel have 15-20% tap breakage risk. We recommend thread milling or helicoil inserts for production runs.
DFM Impact — By the Numbers
Standards
Tolerance & Quality
Tolerance isn't just a number — it's a cost driver, a risk factor, and a trust signal. We take it seriously, and we help you make informed decisions about every dimension on your drawing.
CMM inspection in progress — every critical dimension verified against drawing specifications
Standard Tolerances
±0.05mm for general features, ±0.01mm for critical dimensions, ±0.005mm for precision features on request.
Surface Finish
Ra 0.4 to Ra 3.2 standard range, mirror polish available for mold cavities.
GD&T Compliance
Full geometric dimensioning and tolerancing per ASME Y14.5-2018.
Cost Impact
Tighter tolerances increase cost exponentially. We help you specify what matters and relax what doesn't.
Tolerance by Process
Not all processes achieve the same precision. Here are the realistic tolerance ranges for each capability — what we quote is what we deliver.
| Process | General | Precision | Surface |
|---|---|---|---|
| CNC Milling (3-axis) | ±0.05mm | ±0.01mm | Ra 0.8 |
| CNC Milling (5-axis) | ±0.03mm | ±0.005mm | Ra 0.4 |
| CNC Turning | ±0.03mm | ±0.008mm | Ra 0.4 |
| Wire EDM | ±0.01mm | ±0.003mm | Ra 0.2 |
| Sinker EDM | ±0.02mm | ±0.005mm | Ra 0.4 |
| Injection Mold | ±0.10mm | ±0.03mm | SPI A1 |
Tolerance vs. Cost Impact
Tighter tolerances increase cost exponentially. Specifying the right tolerance for each feature is one of the most impactful cost decisions in precision manufacturing.
Our approach: We review every dimension in your drawing and flag where tolerances can be relaxed without affecting function — typically reducing cost by 20-35% on precision parts. We don't just machine to print; we think about why each tolerance exists.
Verification
Inspection & Validation
Trust is earned through documented proof — not claims. Every inspection method below includes specific equipment, measurement ranges, and reporting standards. No vague quality promises.
CMM Inspection
Full dimensional reports on every critical feature using Zeiss Contura CMM with Calypso software. Measurement accuracy: ±0.0018mm + L/350. Reports include actual vs. nominal with GD&T deviation analysis.
First Article Inspection (FAI)
AS9102-compliant FAI reports for new parts and process changes. Form 1 (part number), Form 2 (product), and Form 3 (characteristic) — full documentation for aerospace and medical traceability requirements.
In-Process Checks
Three-gate inspection protocol: setup verification (first-off approval), mid-run SPC sampling (every 25-50 pcs), and final dimensional audit. Catches process drift before it affects delivery quantities or quality.
Surface Roughness Measurement
Mitutoyo SJ-410 profilometer with Ra, Rz, and Rq parameters. Measurement range: 0.01–40μm. Documented per spec — every surface finish callout on your drawing is verified and reported.
Material Certification
Mill test reports (EN 10204 3.1) and full material traceability on every order. Heat number tracking from raw material through finished part. Available for all metals and engineering plastics.
Visual & Dimensional Verification
Photographic documentation of finished parts at 10×–50× magnification. Go/no-go gauging for threads, press-fit diameters, and critical features. Visual inspection per MIL-STD-105E sampling plans.
Our Inspection Commitment
No part ships without documented proof of conformance. We don't rely on operator judgment — every critical dimension is measured, recorded, and reported. If a dimension is out of spec, you'll know before the part leaves our facility, not after it arrives at yours. All inspection data is retained for a minimum of 7 years for full traceability.

Client Feedback
What Our Clients Say
Specific feedback from engineers and sourcing managers — not generic endorsements. Real numbers, real outcomes.
“We sent a bracket design that had three tolerance callouts tighter than they needed to be. Precision Edge caught it during DFM review, recommended relaxing two of them, and saved us 28% on unit cost — with zero impact on function. That kind of manufacturing insight is why we keep coming back.”
Mark Thornton
VP Engineering, AeroDyne Systems
Aerospace“The mold for our PEEK housing was delivered in 6 weeks with full FAI documentation — 43 critical dimensions, all in spec. Zero rework on first article. That level of precision from a first run tells us the tooling and process control are solid.”
