Industries We Serve
Yijin Solution supports aerospace manufacturers, commercial aviation suppliers, ground support equipment companies, and unmanned aircraft developers. We manufacture custom parts for cabin assemblies, inspection equipment, test systems, and commercial UAV platforms, with flexible support from prototyping and qualification builds to low-volume production.
Manufacturing Capabilities for Aerospace
Yijin Solution combines CNC milling, CNC turning, sheet metal fabrication, and surface finishing for aerospace projects. Managing these processes through one supplier helps reduce drawing-control issues, inspection inconsistencies, and communication delays. Our team supports prototypes, qualification builds, and low-volume production using aerospace-grade metals and engineering plastics.
CNC Machining
Aerospace CNC machining covers milled brackets, housings, fittings, and thin-wall structures in Aluminum 6061, 7075, and 2024, plus titanium alloys. Machined features hold to plus or minus 0.01 mm on suitable geometry, with standard work at plus or minus 0.05 mm.
Swiss Turning
Swiss turning produces small-diameter shafts, pins, and bushings, run across a fleet of more than 80 Swiss-type lathes. Slender hardware holds closer to nominal on a Swiss lathe, since the guide bushing supports the bar at the cut.
Sheet Metal Fabrication
Aerospace sheet metal fabrication covers formed panels, cabin and interior hardware, and enclosures in aluminum and stainless steel. Precision tolerance reaches plus or minus 0.10 mm and standard tolerance plus or minus 0.30 mm, subject to material thickness and bend count.
Custom Fasteners
Cold heading and secondary threading produce custom aerospace fasteners to plus or minus 0.02 mm across 150 cold heading machines. Hardware normally sourced separately from machined parts comes from the same facility and the same quality system.
Surface Finishing
Anodizing, chromate conversion, and passivation protect aluminum and stainless steel components against corrosion in service. Finish selection is confirmed at the quote stage, since coating thickness affects fit on close-tolerance features.
Parts We Make for Aerospace
We manufacture custom aerospace parts from customer drawings and 3D CAD files. Each part is produced to the specified material, tolerance, finish, and inspection requirements.
- Structural brackets in Aluminum 7075, five-axis milled where weight and stiffness both matter.
- Equipment housings and enclosures, machined or fabricated in aluminum with thin wall sections.
- Hydraulic and pneumatic fittings turned in stainless and titanium, with controlled sealing face finish.
- Precision shafts and pins, Swiss-turned at small diameters and held at length. Bushings and spacers in bronze and stainless for bearing and wear surfaces.
- Cabin and interior panels formed from aluminum sheet, where flatness and finish carry the part.
- Latches and trim fittings machined in aluminum and anodized for wear resistance.
- Galley and seat hardware components, fabricated and machined at repeat production volumes.
- Custom fasteners cold-headed to plus or minus 0.02 mm with secondary threading.
- Ground support equipment components machined and fabricated in steel and aluminum.
- Sensor and avionics housings milled from aluminum with thin walls and shielding features.
- Test fixtures, jigs, and check gauges machined for assembly and inspection verification.
From Idea to Production
Every aerospace project starts with a free DFM review at the quote stage, where tolerances, datums, and material choices are settled before the first cut. Prototypes typically run 3 to 7 days, and design revisions are absorbed within the same fixturing rather than restarting qualification. Production scales in the same facility under the same quality system, so parts do not requalify at a second supplier. Inspection and documentation travel with the parts at both stages, and earlier concept work is supported through new product development services.
Why Aerospace Manufacturers Choose Yijin
Precision and Quality
Yijin Solution machines components to plus or minus 0.01 mm on suitable features under an ISO 9001-certified quality system. Zeiss CMM dimensional reports are available on request.
Prototyping to Production
Prototypes typically run 3 to 7 days and move into production in the same facility, with no requalification at a second supplier.
Material Breadth
Aluminum 6061, 7075, and 2024, titanium alloys, stainless steel and nickel alloys, and engineering plastics are machined or fabricated in-house.
Order Any Size
887 pieces of production equipment, including more than 136 CNC machining centers, support single prototypes and repeat production runs alike.
Cost-Effective
Direct factory pricing applies at every volume, and the free DFM review removes tolerance rework before cutting starts.

Aerospace Custom Parts Manufacturing FAQs
Which certifications does Yijin hold for aerospace work?
The certifications held are ISO 9001, ISO 14001, ISO 13485, and IATF 16949. AS9100 is not among them, and the quality system instead provides documented inspection, material certificates, and lot traceability on aerospace orders. AS9100 is the aerospace standard published by SAE International. It adds configuration management, risk management, and counterfeit part controls for programs that require it.
What tolerances are achievable on aerospace components?
Machined features reach plus or minus 0.01 mm where geometry and material allow. Standard machined work sits at plus or minus 0.05 mm, and sheet metal precision work reaches plus or minus 0.10 mm. Achievable tolerance depends on feature type, part geometry, and the inspection method agreed upon at the quote stage.
Which aluminum and titanium grades are machined for aerospace parts?
Aluminum 6061, 7075, and 2024 cover most machined aerospace structures. Titanium alloys, stainless grades, and nickel alloys follow. Grade choice affects cost and lead time since titanium machines more slowly and consumes more tooling. Material alternatives form part of the DFM review at the quote stage.
Are first article inspection reports and material certificates available?
First article inspection reports and material certificates are both available on request. The inspection report records measured dimensions against the drawing. The material certificate traces the stock to its mill heat. Both are prepared before shipment when specified on the purchase order.
Does Yijin accept defense or export-controlled aerospace work?
Aerospace work here is scoped to commercial applications. That covers civil aircraft interiors, ground support equipment, commercial unmanned systems, and tier supplier components. Defense, military, and export-controlled programs sit outside that scope. Buyers with commercial programs are the intended fit.
What lead times apply to aerospace prototypes and production runs?
Prototypes typically run 3 to 7 days, and production runs typically complete in 2 to 4 weeks. Complexity, finishing scope, and inspection requirements are the main drivers of both figures. Confirmed dates are issued with the quote.
