How to specify electroplating gloves for anodising, pickling and wet metal finishing lines, including EN ISO 374 chemical checks, PVC versus nitrile gauntlets, cuff length, wet grip, MOQ, sampling and export realities.
The Short Answer for Plating Buyers
For electroplating, anodising, pickling and passivation lines, do not start with a thin disposable inspection glove. Start with a supported PVC or nitrile gauntlet in 35 cm or 45 cm length, then check it against the actual bath list. Sulphuric acid anodising, hydrochloric acid pickling, sodium hydroxide cleaner, nickel sulphate, zinc chloride, chromate conversion and nitric acid bright dip do not attack glove materials in the same way. Temperature matters as well: a room-temperature EN ISO 374 result does not automatically cover a 55 degree Celsius tank. A practical first sample for rack handling is a cotton interlock or cotton jersey supported glove with full PVC coating, rough palm, 35 cm cuff and finished palm thickness around 1.1 to 1.4 mm. It is not elegant, but it gives usable wet grip and abrasion life when workers drag jigs over tank lips. For plug fitting, masking, inspection and light transfer work, an unsupported nitrile gauntlet around 0.38 to 0.55 mm in 33 cm to 38 cm length gives better finger feel, but it will usually tear sooner at the thumb crotch and cuff edge. Ask for EN ISO 374-1:2016+A1:2018 chemical data, not only a pictogram. The useful document is the permeation table showing chemical name, concentration and breakthrough level. EN ISO 374-5:2016 is relevant where micro-organism contamination is assessed, but it does not prove acid resistance. GloveMark can develop and private-label PVC, nitrile, dipped, sewn and knitted industrial gloves through our factory network. We do not present one universal electroplating glove for every bath. If the chemical list is unknown, sampling is guesswork.
PVC, Nitrile and Neoprene Are Not Interchangeable
PVC gauntlets are common on plating floors because they are cost-effective, stable in standard export colours and easy to make in 27 cm, 35 cm, 40 cm and 45 cm lengths. A typical construction uses a cotton interlock, cotton jersey or polyester-cotton liner pulled onto a former, dipped in PVC plastisol, textured if required, then oven-cured. Rough PVC or embossed PVC grips wet racks well, and supported PVC is a sensible choice for general wet handling, alkaline cleaning and low to medium acid splash where the lab data supports it. PVC is not the answer for every tank. It can stiffen in cold workshops, it is poor for many solvents, and strong oxidising mixtures need proper chemical review. Buyers sometimes send one sentence such as for acid use, but that is not enough for a factory to choose a polymer. We need the chemical name, approximate concentration, operating temperature and contact type: splash, immersion, drip from racks or wiping. Nitrile gauntlets are normally chosen where oil resistance, puncture resistance and dexterity matter. Unsupported nitrile in 13 inch or 15 inch length works well for fitting masking plugs, handling small zinc die-cast parts or checking threaded holes. Supported nitrile with sandy or rough finish is stronger, but costs more than basic PVC and may need a higher MOQ if the liner and former are not already running. Natural latex has good elasticity, but many industrial buyers avoid it because of allergy policy and weaker oil resistance. Neoprene can perform well for some acids, caustics and mixed wet chemical jobs, but it is not a standard low-cost Yiwu work-glove item in the same way as PVC. High-end multilayer laminate gloves for concentrated hydrofluoric acid, aggressive solvent stripping or unknown waste treatment are outside our normal knit, dip, sew and leather glove core. In that case we would decline the order or point the buyer towards a specialist chemical PPE supplier rather than print a logo on the wrong glove.
Cuff Length, Shape and Inspection Points
A 27 cm glove is usually a bench glove, not a tank glove. It may suit dry inspection or short rinse work, but it leaves the forearm exposed when workers lift a wet rack and liquid runs backwards. For anodising and electroplating lines, the common export lengths are 35 cm, 40 cm and 45 cm. A 35 cm gauntlet covers past the wrist and lower forearm. A 45 cm gauntlet gives better splash coverage when reaching across wide tanks or lowering baskets, but it uses more compound, needs longer formers and packs with more air volume. Carton math is not a small detail. A medium 35 cm supported PVC gauntlet may pack around 60 to 72 pairs per export carton, depending on thickness and size mix. A heavy 45 cm glove may drop to 36 to 48 pairs per carton. That changes sea freight cost per pair and can make two similar FOB Ningbo quotes look different only after carton dimensions are compared. Always ask for pair count, carton size and gross weight before approving a price. Specify the cuff mouth. Straight-cut cuffs are cheaper and faster. Rolled cuffs resist tearing at the opening but add labour and may feel bulky. An elasticated inner cuff can help in dry mechanical work, but on a wet chemical line it may trap liquid if the outer glove is breached. For private-label orders, we ask buyers to confirm size range such as 8, 9, 10, 11 or S to XL, hand-specific or ambidextrous design, cuff length tolerance such as plus or minus 10 mm, and whether cuff printing is required. Factory inspection can check length, palm thickness, coating continuity, pinholes visible under normal inspection, weight, size marking and packing. We normally use an ANSI/ASQ Z1.4 style sampling plan, commonly general inspection level II with an agreed AQL for major and minor defects. That is not a chemical permeation test. EN ISO 374 performance must come from a competent lab test, not from a packing-table visual check.
Wet Grip Must Match the Workpiece
A smooth chemical glove may look clean in a catalogue, but it is often wrong for plating work. Operators lift wet aluminium profiles, oily wire baskets, zinc-plated brackets, titanium racks, copper bus bars and sharp masking jigs. Grip texture should be written into the specification: smooth, embossed PVC, rough PVC, sandy nitrile or crinkle finish. If the purchase order only says chemical glove, the supplier may choose the cheapest smooth mould. Rough PVC gives strong wet grip on racks and baskets, but sludge and metal fines can sit in the texture and make rinsing slower. Sandy nitrile gives good oil grip and a more modern feel, especially on small parts, but the life depends on coating thickness and liner strength. Crinkle latex is common in general handling gloves, but latex is usually not our first suggestion for plating chemicals because oil resistance and allergy policy are frequent concerns. For cosmetic anodised aluminium, contamination control matters. Dark PVC can hide dirt during line audits, while white, green or light-blue PVC makes contamination easier to see. Some black compounds can leave visible smears on light aluminium if the formulation is poor or under-cured. Before ordering 10,000 pairs, run a simple workshop check: rub the palm on a clean aluminium coupon for 20 to 30 cycles, rinse as the operator would, and inspect under normal production lighting. This does not replace EN testing, but it catches marking, shedding and plasticiser-transfer problems early. For heavy racking, supported gloves usually beat thin unsupported gloves because the textile liner spreads pressure across the hand and improves tear resistance at the thumb crotch. For fine masking and plug work, unsupported nitrile may still be the better glove. Many plating plants need two styles, not one compromise glove that is too clumsy for detail work and too weak for rack handling.
Standards Wording Must Be Exact
For EU and UK supply, chemical protective gloves should be discussed under PPE Regulation EU 2016/425 and the relevant EN standards. The key chemical standard is EN ISO 374-1:2016+A1:2018. Type A, Type B and Type C depend on how many listed chemicals reach at least permeation performance level 2, which means breakthrough time of 30 minutes or more under the test method. EN ISO 374-5:2016 covers protection against micro-organisms. EN 388:2016+A1:2018 is still important because plating workers handle metal parts and racks, so abrasion, cut, tear and puncture are real failure points. The code letters are not decoration. In EN ISO 374-1, K is sodium hydroxide 40 percent, L is sulphuric acid 96 percent, M is nitric acid 65 percent, J is n-heptane and O is ammonium hydroxide 25 percent. A glove marked Type B KLM is not the same as one marked Type B JKO. If your bath is hydrochloric acid 10 percent at 45 degrees Celsius, nickel sulphate solution or chromic acid mix, ask whether that exact chemical or a relevant equivalent has been tested. Do not assume the letter set covers every plating tank. For North American buyers, ANSI/ISEA 105 may be requested for mechanical or cut information, but it does not replace chemical permeation data. SDS sheets from the chemical supplier help the glove supplier understand the risk, but the SDS is not a glove certificate. We can print CE, UKCA or EN markings only when the technical file and test report support them. We do not print compliance marks just to make a private-label glove look more expensive.
Sampling, MOQ and China Export Reality
A sensible sampling plan is three constructions, not ten colours. For a plating buyer, we would normally sample one 35 cm rough PVC supported gauntlet, one heavier 45 cm PVC gauntlet and one 13 inch or 15 inch unsupported nitrile gauntlet. Standard colours such as black, blue, green and yellow are easier to control than Pantone-matched chemical compounds. If the buyer wants a special colour, we need to check whether the pigment affects cure, surface marking or minimum compound batch size. For existing formers and standard materials, factory samples usually take 7 to 14 days after size, cuff mark and packing details are confirmed. Custom cuff printing, screen-printed logos, header cards, barcoded polybags or retail cartons can add 3 to 7 days because artwork, films, plates or print screens must be prepared. Pre-production samples should be approved for length, thickness, grip, cuff opening, colour and packaging before bulk production starts. MOQ depends on whether the line is already running that glove family. Standard OEM electroplating gloves usually start around 3,000 to 5,000 pairs per style and colour. A non-standard 45 cm former, custom compound colour, special texture or small split across many sizes can push the practical MOQ higher. Bulk lead time is commonly 4 to 7 weeks after approved sample and deposit, and longer before Chinese New Year when dipping lines and carton suppliers are crowded. Most B2B glove orders are quoted FOB Ningbo or FOB Shanghai, with EXW available for buyers using their own consolidator. For long gauntlets, freight is often limited by carton volume before weight. Ask for carton dimensions, pairs per carton, gross weight and HS code confirmation before comparing suppliers. A quote that is a few cents cheaper may simply have a shorter cuff, thinner palm or looser inspection level. On an electroplating line, those savings usually fail at the exact places workers complain first: cuff edge, thumb crotch, palm wear and wet grip.
Quote Comparison Welcome
If you already have a quote from another supplier, send it over with the spec sheet - we will quote against it line by line and tell you where we are cheaper, where we are not, and why. Most useful for buyers on order #2 or #3.
