Trusted Aerospace Custom Metal Parts Supplier for Zero-Defect Components
Aerospace CNC Machining & Precision Metal Parts
Qingdao Inside Industry Co., Ltd. machines flight-critical aerospace components in titanium Ti-6Al-4V, Inconel 718, and 7075-T651 aluminum for aircraft OEMs and defense contractors across Europe, North America, and the Middle East.
Our 5-axis CNC machining centers hold tolerances to ±0.005 mm on complex geometries including turbine housings, actuator brackets, and thin-wall structural panels. All production is supported by Hexagon CMM dimensional verification, full material traceability from certified mill sources, and First Article Inspection (FAI) reports structured to AS9102 requirements.
Our manufacturing facility in Chengyang District, Qingdao, Shandong Province sits 25 km from Qingdao Jiaodong International Airport (TAO) and 35 km from Qingdao Port (CNQDG) — providing fast airfreight response for AOG support and competitive sea freight lead times to Hamburg, Rotterdam, and Long Beach.
AS9100-Aligned Quality Documentation
Our quality management system operates under ISO 9001:2015 certification. For aerospace customers, we produce First Article Inspection Reports (FAIR) structured to AS9102 requirements, CMM inspection reports with GD&T callout verification, material test reports (MTRs) with heat and lot number traceability, and Certificates of Conformance (CoC) for each shipment. PPAP Level 3 packages are available for automotive-crossover programs.
Qingdao Port Logistics Advantage for Global Supply Chains
Qingdao is China’s third-largest container port by throughput. Weekly direct sailings to Hamburg (28 days transit), Rotterdam (30 days), Felixstowe (32 days), and Long Beach (18 days) give European and North American aerospace procurement teams predictable delivery windows without routing through Shanghai or Shenzhen consolidation. For urgent AOG requirements, Qingdao Jiaodong International Airport (TAO) provides same-day airfreight booking to major European hubs.

5-Axis CNC Machining for Tight-Tolerance Aerospace Parts
Our machining cells operate on 5-axis CNC centers capable of completing complex aerospace geometries in a single setup, eliminating re-fixturing error on turbine housings, impeller bodies, and structural brackets. We hold positional tolerances to ±0.005 mm and surface roughness to Ra 0.4 μm on finish passes.
Exotic Material Capability — Titanium, Inconel & Aerospace Aluminum
Cutting titanium Ti-6Al-4V and Inconel 718 at production rates requires specific tooling strategies, controlled cutting speeds, and coolant management that generalist shops cannot sustain. Our machinists have processed these materials across engine component, airframe bracket, and fastener programs, and we maintain dedicated tooling inventories for each alloy family to protect against cross-contamination.

Mission-Critical Aerospace Applications
At Qingdao Inside Industry Co., Ltd., our deep technical expertise in Aerospace Parts Customization supports leading aircraft OEMs, aerospace suppliers, and defense contractors worldwide;
We ensure full material traceability and compliance with AS9100 and ISO quality standards across every application, delivering components that withstand the rigors of flight.

Engine Components & Turbine Housings
We machine turbine housing bodies, precision shafts, and specialized engine brackets in Inconel 718 and Ti-6Al-4V. Wall thickness on turbine housings typically runs 2.0–4.0 mm with bore tolerances to H7. All engine components are supplied with full MTRs, CMM reports, and individual part serialization on request.

Flight Control System Linkages & Actuator Housings
Flight control linkages and hydraulic actuator housings require consistent positional accuracy across full production batches — not just first articles. We implement in-process CMM sampling at defined batch intervals and provide CPK data for critical dimensions on production orders of 50 pieces or more.

Avionics & EMI-Shielded Electronic Enclosures
Avionics enclosures machined in 6061-T6 and 7075-T651 aluminum are finished with Alodine 1200 chemical conversion coating or Type II anodizing to maintain electrical conductivity while providing corrosion resistance. Wall thickness tolerances of ±0.05 mm and flatness of ±0.1 mm are achievable on standard enclosure programs.

Landing Gear & Load-Bearing Structural Parts
Load-bearing landing gear components in 7075-T7351 aluminum and 17-4 PH stainless steel are machined with attention to fatigue life — we apply conservative finishing passes to achieve Ra 0.8 μm on all stress-concentration surfaces, and we provide material hardness verification alongside the CMM report for each batch.

Cabin Interior Fittings & Precision Airframe Panels
Custom aluminum seat track fittings, overhead bin hardware, and precision airframe panel brackets are fabricated using TRUMPF fiber laser cutting and CNC press brake forming, with Type II anodizing or powder coat finish. Form tolerances on complex formed panels are held to ±0.15 mm.

Engineering & Quality Control
CMM Dimensional Verification & SPC Monitoring
Every aerospace program receives a First Article Inspection Report (FAIR) generated on our Hexagon coordinate measuring machine, documenting all drawing dimensions against actual measured values with GD&T callout verification per ASME Y14.5. For production runs, we implement Statistical Process Control (SPC) sampling at defined intervals — standard is every 10th piece on tolerances ±0.01 mm or tighter.
Material Certification & Full Heat-Number Traceability
Aerospace material stock is sourced exclusively from certified mill suppliers. Each delivery is received with a Material Test Report (MTR) documenting chemical composition, mechanical properties, heat number, and lot number. These MTRs are stored against the production work order and referenced in the shipping documentation for every batch.
First Article Inspection (FAI) per AS9102
Our FAI packages include: AS9102 Form 1 (Part Number Accountability), Form 2 (Product Accountability), and Form 3 (Characteristic Accountability) — with dimensional results, material certifications, surface finish records, and process certifications collated into a single audit-ready package. Digital copies are available via secure file transfer.
Surface Treatment & Coating for Aerospace Components
All surface treatment processes are coordinated through NADCAP-aligned vendors within the Shandong Province supply chain. Process certifications and coating test results are included in the shipping documentation package.

Frequently Asked Questions
Aerospace Component Sourcing
Our quality management system is certified to ISO 9001:2015. We are not currently AS9100 Rev D registered, but our quality procedures are structured to AS9100 requirements: we produce FAIRs to AS9102, maintain full material traceability with heat-number-level MTRs, implement SPC monitoring on critical dimensions, and deliver complete documentation packages. Customers requiring AS9100 registration as a mandatory supplier qualification criterion should confirm this with us before RFQ submission.
Our largest CNC machining envelope is 2,000 × 1,200 × 800 mm on our large-format machining center. This accommodates wing rib sections, large bulkheads, and fuselage structural brackets. For parts exceeding these dimensions, we can discuss split-machining with precision alignment features — contact us with your drawing.
Yes. Every aerospace program ships with Material Test Reports (MTRs) from the original certified mill, documenting chemical composition, mechanical properties, heat number, and lot number. A Certificate of Conformance (CoC) is issued per shipment confirming that all parts were manufactured to the applicable drawing revision, material specification, and process requirements.
We do not currently hold US ITAR registration. For non-ITAR defense components and dual-use aerospace parts, we handle technical data under NDA with controlled access limited to the engineers assigned to the program. Customers with ITAR-controlled parts should clarify export control classification before submitting technical data — we can advise on commonly applicable exemptions for manufacturing services.
First-off CNC machined prototypes in titanium or aluminum typically ship within 7–10 working days from drawing approval and material confirmation. Inconel 718 prototypes run 10–14 working days due to tooling setup and cutting speed constraints. We offer expedited 5-day service for urgent R&D and flight test requirements — contact us to confirm material availability.
Yes. DFM review is provided at no charge for all new programs. Our engineers review your 3D STEP or IGES models and 2D drawings and return a written report within 2 working days identifying machining feature conflicts, minimum wall thickness risks, surface finish achievability, and tolerance stack concerns. DFM review does not require a purchase commitment.
