Commercial machine shops rarely know aerospace documentation or MIL-SPEC finish standards. These are the failures that follow.
Material Traceability
Generic material sourcing fails aerospace receiving inspection.
Aerospace programs need AMS material certifications and a full Certificate of Conformance for every part. Commercial-grade sourcing leaves traceability gaps that fail audits and delay schedules.
Material is sourced to AMS specifications, with MTRs, CoCs and FAI reports on every aerospace order.
MIL-SPEC Surface Finishes
Standard commercial anodize does not meet MIL-A-8625.
MIL-A-8625 Type II and Type III set coating thickness, alloy class and seal requirements that commercial anodize shops often miss. The wrong finish type, even on the right material, is rejected at receiving inspection and needs full rework.
DFM review specifies the MIL-SPEC finish, alloy type and coating thickness range before production.
Thin-Wall Distortion
Lightweighting pushes wall thickness to the edge of machinability.
Weight-optimised aerospace parts often have 0.5 to 1 mm walls that distort during machining. Without the right fixturing, parts measure in spec on the machine and out of spec in the assembly.
Thin walls are flagged during DFM, with a fixturing strategy and operation sequence that limits distortion.
How an Aerospace Order Works
Each order gets an aerospace-specific review before any cutting starts, and the full documentation pack ships with the parts.
- 1Quote in 24 to 48 hoursUpload a STEP File and Drawing
STEP, IGES or a 2D drawing. Include the material specification (AMS grade), surface finish callouts and any assembly context. An NDA is available on request.
- 2Aerospace DFM Review
Your engineer checks the AMS material specification, MIL-SPEC finish requirements, thin-wall fixturing strategy and whether the tolerances are achievable. Issues are resolved before cutting starts.
- 3Material and Finish Confirmed
AMS alloy grade, MIL-SPEC finish type and thickness, and any special requirements are confirmed and written into the work order before the order is confirmed.
- 4Manufacture and In-Process QC
3-axis and 5-axis CNC machining with in-process dimensional checks and CMM inspection of critical features. Coating thickness and alloy class are confirmed at the supplier, before shipment.
- 512 days standardDelivery with Aerospace Documentation
A Material Test Report to AMS spec, Certificate of Conformance, dimensional inspection report and surface finish certification ship with every order. First Article Inspection reports are available on request.
Results
"Factorem's DFM review flagged a MIL-SPEC finish specification issue before we went to production, saving us a full rework cycle. The material documentation they provide passes our receiving inspection without any back-and-forth."
- ISO 9001:2015 quality management (TÜV SÜD)
- AS9100-capable suppliers in the network
- MTRs and CoCs to AMS spec on every order
Frequently Asked Questions
If your question is not here, an engineer can answer it directly.
Do you manufacture ITAR-controlled parts?
No. Factorem makes commercial aerospace and defense components under EAR99 and equivalent regulations only. It does not make ITAR-controlled hardware or defense articles on the US Munitions List (USML).
What aerospace materials do you work with?
AL 6061, AL 7075, Ti-6Al-4V, SS 17-4 PH, SS 316L, Invar 36 and engineering polymers. All structural materials are sourced to AMS specifications with full traceability documentation.
Can you provide material certifications (MTRs and CoCs)?
Yes. Every aerospace order ships with a Material Test Report to AMS specification, a Certificate of Conformance and a dimensional inspection report. First Article Inspection reports are available on request.
What MIL-SPEC surface finishes can you apply?
MIL-A-8625 Type II and Type III hard anodize, MIL-DTL-5541 chromate conversion coating, passivation, electroless nickel and black anodize. The DFM review specifies the finish type and thickness for your alloy and application.
What tolerances can you achieve on structural aerospace components?
±0.005 mm on critical bore and flatness features for avionics enclosures, optical housings and interface plates. Structural brackets are typically ±0.01 mm. Tighter tolerances are reviewed case by case during DFM.
Do you have AS9100 certification?
Factorem holds ISO 9001:2015 certification (TÜV SÜD). The supplier network includes AS9100-capable facilities for aerospace-grade quality requirements, and their certification documents are available on request.
