Factory-level guide to sourcing aerospace assembly gloves for FOD-sensitive work, covering 15 gauge liners, PU or nitrile palms, silicone control, EN388 testing, packing, MOQ, lead time and realistic OEM limits.
Start With FOD Risk, Not The Glove Catalogue
For aircraft cabin fit-out, avionics rack assembly, composite trimming or MRO bench work, the first buying question is not softness. It is whether the glove can shed fibre, drop coating particles, transfer silicone, hide a loose rivet or contaminate a bonding surface. A 13 gauge polyester nitrile glove that works well for warehouse picking can still fail in an aerospace cell if black fibre appears on a white sidewall panel, the cuff leaves yarn tails near M4 fasteners, or the palm coating flakes after storage in a hot tool crib. We normally split aerospace assembly gloves into at least four use cases before quoting: dry precision assembly, oily maintenance, sharp-edge handling and composite or sealant work. Dry precision work often starts with a 15 gauge nylon-spandex liner and thin PU palm. Oily maintenance usually needs micro-foam nitrile or sandy nitrile on a 13 gauge or 15 gauge nylon-spandex liner. Sharp aluminium sheet, brackets or machined edges may need HPPE, steel fibre or glass fibre blend yarn to reach ANSI/ISEA 105 A2 to A4 or EN388 cut B to D, but those yarns change lint behaviour and hand feel. Composite layup or sealant work may need a disposable nitrile or EN ISO 374 chemical glove, not a knitted dipped assembly glove. One aerospace plant can easily need 3 or 4 SKUs. Trying to force one glove across cabin interiors, oily hydraulic work and cut-risk deburring normally creates complaints: either too much lint, not enough grip, poor dexterity or the wrong chemical protection. Our job as a factory is to narrow the construction, not to sell the thickest glove in the catalogue.
Low-Lint Construction Choices We Can Actually Control
In a Yiwu knit-and-dip production route, lint control starts with yarn type, filament quality, knitting tension and cuff finishing. Nylon filament is cleaner than cotton, acrylic or recycled polyester. A 15 gauge nylon-spandex shell gives a smoother surface and better fingertip feel than a 10 gauge or 13 gauge economy polyester shell. For fine assembly we normally avoid terry loops, brushed fleece, loose liner plating and exposed latex elastic because these increase fibre release. A knitted cuff can be overlocked, but the buyer should approve the cuff seam because cut yarn tails are a common FOD complaint. PU palm coating is thin, flexible and good for screws, clips, wiring connectors and small fasteners. It is usually the first sample for dry assembly. It is not the best choice for hydraulic oil, fuel residue or wet maintenance bays. Micro-foam nitrile gives better oil grip and abrasion life. Sandy nitrile gives stronger mechanical grip but can feel too rough on painted, polished or anodised parts. We can specify palm-only dip, three-quarter dip or full dip. For aircraft interior work, palm-only is often safer because it reduces coating area, improves breathability and leaves fewer coated edges that may crack after long storage. Construction details should be written into the purchase specification, not left to a sample photo. Useful wording includes 15 gauge nylon-spandex liner, PU palm-only coating, elastic knitted cuff, no brushed lining, no latex coating, no silicone intentional addition, size overedge colours and carton lot marking. If the buyer only writes low lint glove, different suppliers will interpret it differently.
Standards: Useful Tests, But Not Aerospace Approval
EN388:2016 plus A1:2018 is useful for comparing abrasion, coupe cut, tear, puncture and ISO 13997 cut resistance. A light PU precision glove may target abrasion level 3 or 4, tear level 2 or 3 and low puncture resistance. A cut-resistant assembly glove may target EN388 cut B, C or D, or ANSI/ISEA 105 A2, A3 or A4, depending on the edge risk. These numbers help procurement compare gloves, but they do not mean the glove is approved by Boeing, Airbus, COMAC, Embraer or any MRO programme. CE or UKCA documentation also has limits. A PPE file can cover the tested model and production route, but it does not automatically cover a changed yarn, changed coating, different colour pigment, printed pouch or new supplier of PU resin. If the buyer needs Category II PPE under Regulation EU 2016/425, the actual glove construction should match the technical file and the user instruction. A generic EN388 report from a similar glove is not enough for a controlled aerospace supply chain. GloveMark does not claim aerospace OEM approval unless the customer supplies the programme requirement and the product passes that approval route. If the plant requires REACH SVHC screening, RoHS-related documentation for electronics work, DMF below a named limit, or silicone-free verification, those checks must be placed with a recognised lab on the actual production material. We can prepare samples and production lots for testing, but we will not turn an industrial glove into a programme-approved aerospace glove by wording alone.
Silicone, DMF And Surface Contamination Checks
Silicone control matters around bonding, painting, sealing and composite layup. The risk may come from palm coating additives, release agents, yarn lubricants, printing ink, polybag slip agents or even packing tape. If the buyer needs silicone-free aerospace assembly gloves, the purchase specification should state the test method, sample type and acceptable limit before sampling. A supplier declaration is weaker than a lab report on the finished glove or coating film. On the dipping line we can segregate materials and avoid intentional silicone additions, but we cannot confirm invisible residue by eyesight. PU coated gloves can raise DMF questions because dimethylformamide is used in some PU processes. EU buyers and larger aerospace suppliers may require DMF control under REACH or their own restricted substance list. Nitrile coatings avoid the same PU solvent concern but bring different grip, odour and ageing behaviour. Water-based PU options exist in the market, but they must still be tested as the finished glove, not assumed clean because the coating name sounds safer. For composite layup with epoxy resin, sealant application, MEK wiping, fuel contact or hydraulic fluid immersion, do not assume a 15 gauge PU or nitrile palm glove is chemically protective. EN ISO 374 chemical resistance is a different test family, normally for disposable nitrile, neoprene, butyl or chemical gauntlet styles. We can source or coordinate some chemical glove categories, but our in-house knitted dipped line is mainly for mechanical protection, grip and dexterity.
Packing, Colour And Traceability For Controlled Stores
Aerospace stores often reject loose control before they reject glove comfort. For FOD-sensitive issue points, we recommend 1 pair per polybag with size, item code, lot number, production date and country of origin on the inner label. Bulk 12 pairs per master polybag is cheaper, but operators open the bag, mix sizes and lose lot traceability. For light 15 gauge PU gloves, a normal export carton may hold 120 to 240 pairs depending on size ratio, header card, pouch thickness and whether the glove is packed flat or folded. A carton mark should show the buyer ERP item number, PO number, size breakdown, lot number and gross or net weight. Colour is a control tool, not only branding. White or light grey liners show dirt quickly and suit clean assembly areas, but they look old faster in stores. Black hides oil and carbon dust, but any black fibre on a light cabin panel is easy to spot and will be blamed on the glove. Blue is often chosen for visual detection, especially where small glove pieces must contrast with interior trim. For size control, cuff overedge colours are practical: for example S yellow, M green, L brown and XL black. Pantone matching can be requested for yarn or coating, but dipped PU and nitrile have normal batch tolerance and will not match printed paper exactly. For controlled production, we can add incoming yarn lot records, dipping batch records, visual inspection records and final packing lists. Standard inspection is normally by AQL sampling, often AQL 2.5 for major defects and AQL 4.0 for minor defects unless the buyer specifies otherwise. Critical defects such as needles, metal contamination or mixed sizes should be zero tolerance in the packing SOP.
Sampling, MOQ And What GloveMark Will Not Promise
A sensible sampling route is 2 or 3 constructions, not 12 catalogue guesses. For example: 15 gauge nylon-spandex PU palm for dry assembly, 15 gauge nylon-spandex micro-foam nitrile for light oil, and 13 gauge HPPE-nylon-spandex nitrile palm for cut-risk brackets. The buyer should run a wear trial of at least 20 to 50 pairs per work cell, using actual fasteners, touchscreens, aluminium edges, sealants, painted panels and composite surfaces. EN388 testing should follow once the construction is fixed; testing every colour and logo trial wastes time and money. For OEM production, practical MOQ for knitted dipped gloves is usually 3,000 to 5,000 pairs per colour and size mix if yarn and coating are standard. Custom yarn colour, special pouch printing, silicone-control testing, non-standard cuff marking or private mould packaging can push MOQ higher. Normal sample lead time is about 7 to 14 days for standard yarn and coating. Bulk lead time after approved sample is usually 4 to 7 weeks, plus lab testing time if EN388, REACH, DMF or silicone screening is required. Export terms are usually FOB Ningbo or Shanghai, with EXW Yiwu possible for buyers using their own consolidator. GloveMark can make private-label 13 gauge and 15 gauge knitted PU or nitrile palm gloves, HPPE cut-resistant versions, sewn synthetic leather mechanics styles and leather driver gloves. We do not manufacture sterile cleanroom gloves, pilot flight gloves, electrically insulating rubber gloves under IEC 60903, or fully certified EN ISO 374 chemical gauntlets in-house. If your aerospace requirement sits in those categories, the honest answer is referral or sourcing support, not a fake factory claim. For real aerospace assembly gloves, the best specification is narrow: state the work cell, yarn, gauge, coating, test standard, contamination limits, packing method, AQL and Incoterm before price negotiation starts.
