Factory guidance for sourcing robotics maintenance gloves: EN 388 and ANSI cut targets, nitrile coating choice, touchscreen yarn, cuff design, inspection points, MOQ, lead time and export terms for B2B buyers.
Start With Lockout Work, Not Robot Brand
Robotics maintenance gloves should be specified around the locked-out task, not the robot nameplate. A six-axis welding cell, a palletising arm and a small SCARA line expose hands to different hazards, but the regular contact points are similar: cut steel covers, machined aluminium edges, cable ties, M6 and M8 fasteners, sensor brackets, greased linear rails and teach pendants. A general 13 gauge warehouse nitrile glove is usually too vague a specification for this work. For most robot cell service, the starting point we would quote is a 13 gauge HPPE, nylon and spandex liner, sandy nitrile palm coating, EN 388:2016+A1:2018 cut level C or D, and a 6 to 7 cm knitted elastic wrist. If the buyer works to ANSI/ISEA 105, the normal target is ANSI A3 to A5, depending on whether the job involves light adjustment or frequent guarding removal. We would not push ANSI A6 or EN 388 cut F unless the application really needs it, because thicker yarn packages reduce fingertip control. The common sourcing mistake is adding back-of-hand TPR while ignoring the fingertips. TPR ribs look reassuring in a catalogue photo, but they can foul narrow gaps around end effectors and make M4 screw work clumsy. For automation teams we normally prepare two gloves: one dexterity style for inspection, sensor alignment and teach pendant use, and one heavier cut style for gripper rebuilds, sheet-metal guarding and sharp fixture work. One glove rarely does both 2 mm Allen key adjustment and raw-edge guard handling well.
The Construction We Usually Recommend
Our practical main build is 13 gauge HPPE blended with nylon and spandex. Glass fibre or steel fibre can be added to lift cut resistance, but both change hand feel and can create complaints if the liner is poorly plated. A 15 gauge liner gives better touch on small fasteners and push buttons, but it has less cushioning on knuckles and normally wears faster when dragged across cast bases, robot pedestals and rough-painted frames. For the coating, black sandy nitrile is the usual choice. Palm dip gives better breathability and lower cost; 3/4 dip gives more splash coverage when technicians lean on oily rails or reach behind gearboxes. Smooth nitrile is easier to wipe but can slip on polished shafts. PU coating feels clean and thin, but around servo grease, way oil and pneumatic lubricant it is not our first recommendation. Latex has strong dry grip, but oil resistance and latex-allergy concerns make it a weaker fit for mixed maintenance teams. If touchscreen operation is part of the spec, we can knit conductive carbon yarn or copper-based yarn into thumb and index fingertips. This must be tested on the actual teach pendant or HMI, not just on a phone. Older resistive pendants usually respond through many coatings; some capacitive industrial screens need a cleaner conductive path and a thinner coating at the fingertip. We normally ask the buyer to approve pendant response before bulk production, because coating thickness changes after curing and washing can affect touch.
Grease Grip Is a Coating Decision
Servo grease, way oil, anti-rust spray and general maintenance lubricant quickly separate useful robotics maintenance gloves from catalogue samples. Micro-foam nitrile feels soft and flexible on dry tools, but heavy grease can fill the foam structure and reduce grip. Sandy nitrile leaves a rougher surface and usually performs better on oiled M10 bolts, chromed guide rods, pneumatic fittings and painted robot arms. For very oily cells, a 3/4 sandy nitrile dip is often worth the small increase in weight and cost. Before formal lab testing, we can run a simple workshop comparison if the buyer sends the actual oil or grease. Our usual check is 10 grip cycles on an oiled M10 bolt, wipe with a standard cotton rag, repeat after 30 minutes, then compare slip, coating swelling and residue pick-up against the approved sample. It is not an EN or ASTM test, but it catches obvious failures before the buyer spends money on third-party testing. Do not treat a dipped knit glove as a chemical glove. EN ISO 374 claims require tested permeation and degradation data for named chemicals. A thin nitrile-coated liner may resist light splashes, but it is not suitable for brake cleaner soaking, IPA immersion, degreaser baths or solvent cleaning inside a robot cell. If the work includes chemical handling, we would separate the requirement and quote a proper chemical glove, not print a chemical pictogram on a maintenance glove.
Cuff, Colour and Snag Control Matter
Robot cells have cable carriers, pinch points, guard frames and sharp brackets, so cuff design affects safety. For knitted dipped gloves, a 6 to 7 cm elastic wrist is the normal choice because it holds the glove in place and avoids loose fabric. A longer cuff can protect the wrist when reaching past sheet metal, but it may interfere with jacket sleeves. Hook-and-loop closures can work on sewn mechanic gloves, but inside tight automation cells they collect dust and can snag on cable chains. Size control matters more than many buyers expect. We can produce XS to 2XL in most knitted styles, with colour-coded overlock thread and a printed size mark on the back of hand. For vending machines or PPE cribs, this reduces mixed-size returns. During sampling, technicians should check whether the cuff rolls under a sleeve, whether the thumb crotch pulls when using pliers, and whether coating build-up makes M4 or M5 screws hard to start. Colour should support inspection, not only brand identity. Black nitrile hides grease, which workers like, but it also hides contamination and coating cracks. Grey or blue liners show dirt earlier while keeping a black palm for stain control. If a plant uses PPE zoning, we can use a blue liner for electrical cabinet access, grey for mechanical service and orange cuff binding for higher cut level. Pantone-matched yarn is possible, but dyed yarn minimums can push MOQ above a trial order; stock yarn colours are cheaper and usually faster.
What We Can and Cannot Make in Yiwu
GloveMark can quote knitted and dipped robotics maintenance gloves, sewn synthetic mechanic gloves, leather reinforcement patches, TPR back-of-hand versions and private-label packaging. The dipped knit route normally includes yarn preparation, liner knitting, overlock sizing, hand-former loading, nitrile dipping, pre-curing, main oven curing, cooling, optional washing or tumbling, pairing, marking, polybagging and carton packing. EN 388 style markings are printed only after the buyer has a valid test report and approved artwork. For a new dipped knit robotics style, a practical MOQ is usually 3,000 to 6,000 pairs per colour across a sensible size mix. If conductive yarn, custom liner colour or 3/4 dip is required, the MOQ can move higher because yarn and dipping setup cannot be bought pair by pair. Sample development is normally 7 to 14 days when yarn and coating are available; custom dyed yarn, TPR tooling or retail card artwork can add 2 to 4 weeks before bulk production even starts. We do not manufacture certified electrical insulating gloves for live robot cabinet work, and we will not present a nitrile-coated knit glove as an IEC 60903 rubber insulating glove. We also do not make sterile cleanroom gloves for semiconductor robot maintenance; that supply chain needs particle control, ISO-class packaging and sterilisation validation. If the buyer needs arc-flash PPE, chemical immersion gloves or live electrical protection, we can help define where our glove stops, but we will not relabel an ordinary work glove into those categories.
Sampling, Inspection and Buying Numbers
A useful sample set is not one perfect-looking glove. For robot maintenance teams we prefer sending 3 or 4 constructions: 15 gauge nitrile foam for dexterity, 13 gauge sandy nitrile cut C, 13 gauge cut D with 3/4 dip, and a sewn mechanic glove with synthetic leather palm if impact or vibration is part of the job. Technicians should score them after at least one real maintenance shift, not at a meeting table. Check oily tool grip, pendant response, fingertip bulk on M4 screws, cuff roll, seam irritation and coating wear after contact with guard edges. For first production inspection, use ISO 2859-1 rather than a loose visual check. A common setting is critical defects 0, major defects AQL 2.5 and minor defects AQL 4.0, unless the buyer sets stricter limits. Inspection should cover exposed liner at fingertips, coating cracks, uneven dip line, wrong size pairing, missing conductive fingertip, incorrect CE or UKCA artwork, barcode scan, carton marks and pair weight against the sealed sample. For EN 388 or ANSI claims, the marking must match the final approved report, not an early lab trial on a different yarn. A typical export carton for dipped knit gloves holds 120 to 240 pairs depending on gauge, dip coverage and packaging. A 20 ft container can take roughly 70,000 to 110,000 pairs of this category in simple bulk packing; retail headers, inner boxes and mixed-size assortments reduce that. Lead time after sample approval is normally 4 to 7 weeks for standard yarn and nitrile coating. FOB Ningbo or Shanghai is usually cleaner for importers; EXW Yiwu may look cheaper but leaves inland transport, export handling and customs coordination on the buyer. For a distributor launch, a 5,000 to 10,000 pair first order with field feedback is safer than filling a container with an unproven spec.
