A factory-side guide to sourcing TPR impact gloves without wasting money on the wrong mould, poor sizing or unrealistic MOQs. Covers shell materials, back-of-hand layouts, test limits, tooling cost and production checkpoints.
The first decision is not colour or logo, it is the TPR layout
If a buyer sends only a photo and asks for a price on an impact glove, the quote is usually wrong. TPR impact gloves are not one simple category. A back-of-hand design with 8 separate TPR pieces, stitched onto a polyester-spandex back, is a very different factory job from a full dorsal panel with moulded finger bars and a welded cuff badge. Tooling, sewing time and defect risk all change with the TPR layout. On a practical sourcing level, the first three questions should be: is the glove for knuckle bumps or certified impact risk, do you need fingertip coverage, and are you matching an existing mould or creating a new one. Most Yiwu-area factories that make mechanic-style gloves can sew synthetic leather palms, fourchettes, terry thumbs and hook-and-loop cuffs in-house or through stable subcontract steps. Some can also source standard TPR components from existing mould libraries. What many do not do is develop highly specialised oilfield-style impact systems from zero with guaranteed ANSI 138 testing on day one. If you need a new TPR architecture, expect mould development time of roughly 2 to 4 weeks before wear testing, and understand that a new mould is a tooling project, not just a sampling detail.
Understand what EN 388 and ANSI 138 do and do not tell you
Impact glove buyers often mix cut, abrasion and impact into one requirement sheet, but the tests are separate. EN 388:2016+A1:2018 covers abrasion, blade cut, tear, puncture and optional TDM cut plus impact. If the marking ends with P, that means the glove passed the knuckle impact test under EN 13594 methodology as referenced in EN 388. A marking such as EN 388 2121XP tells you there is impact protection on the back of hand, but it does not mean the fingers are covered, and it does not describe how much dexterity is lost. In North America, buyers may ask for ANSI/ISEA 138 for back-of-hand impact. That standard grades impact performance at Level 1, 2 or 3 across knuckles and fingers. A glove can be strong in abrasion and still fail finger impact, especially if the TPR bars are decorative or too thin. Buyers should ask for the exact test report scope, not just a sales statement saying impact glove. If the supplier cannot show whether the sample was tested to EN 388 with P marking, ANSI 138, or neither, treat the glove as an unverified mechanic glove with rubber decoration.
Material choices decide comfort, durability and complaint rate
For the palm, the most common base is synthetic leather from 0.6 mm to 0.9 mm, often with a PU top layer for abrasion resistance. Heavy-duty versions may add a palm patch, silicone print, or thin foam padding in the heel. The back is usually polyester-spandex or nylon-spandex to help fit over the TPR zones. For dexterity, a lighter 0.7 mm synthetic leather with stretch back works well; for rental fleets, construction or maintenance, a thicker palm and reinforced saddle between thumb and index usually survives better. This is where many complaints start. A glove with hard TPR and a stiff 1.0 mm palm may look rugged but feel clumsy in use. A glove with too-soft TPR may pass casual wear trials but deform after carton compression or hot-container transit. We normally advise buyers to specify at least the palm material thickness range, the back fabric composition, whether there is EVA or foam padding, and whether the TPR is sewn, glued, or both. Sewn TPR tabs are slower to assemble but usually more stable than adhesive-only placement, especially in summer container conditions where internal temperatures can exceed 50 degrees C.
Fit is harder than buyers expect because TPR does not scale cleanly
Sizing an impact glove is not the same as sizing a simple polyester glove. When you grade sizes from M to XXL, the palm pattern, finger length and cuff opening change, but the TPR components cannot always be enlarged proportionally without creating mould issues or misalignment. Many factories therefore use one TPR size across two glove sizes, or separate mould sets for M-L and XL-XXL. That is normal, but it needs to be agreed before approval. Otherwise the buyer approves size L, then complains that XXL has exposed fabric between knuckle pieces or cramped finger bars. A proper sample review should include at least two sizes, normally L and XXL, laid flat against the approved measurement chart. In production, the critical checkpoints are TPR placement tolerance, finger crotch symmetry, cuff circumference and overall hand entry. This is not a glove category where you should approve only by appearance photo. Ask for measured specs in millimetres and a wear video gripping a 25 mm tube or tool handle. If the glove cannot close naturally around a handle, the TPR segmentation is wrong even if the lab test later passes.
MOQ and price depend more on tooling and assembly minutes than on fabric
Buyers used to seamless knit gloves are often surprised by the MOQ structure here. A 13 gauge HPPE shell with nitrile palm dip may start at 1,200 to 3,000 pairs per size-colour, but sewn TPR impact gloves usually need higher commitment if you want a unique back-of-hand design. For standard mould-library styles, MOQ may be around 1,000 to 2,000 pairs per style spread across practical sizes. For a custom TPR mould, many factories will want roughly 3,000 to 5,000 pairs to amortise tooling and sampling time, plus a mould charge that can sit anywhere from a few hundred to over a thousand US dollars depending on complexity and number of pieces. Pricing also moves fast with small construction changes. Adding a terry sweat wipe, touchscreen conductive thumb and index, neoprene cuff panel, reflective piping or full silicone palm print can each add cost and rejection risk. For normal OEM mechanic-impact gloves, ex-works pricing can vary widely by construction, but buyers should be suspicious of very low offers that include custom TPR, retail hangtags and low MOQ all together. In real production, these gloves are labour-heavy. More sewing operations usually matter more than the raw TPR resin cost.
Approve them like a sewn protective product, not a commodity giveaway glove
The right approval flow is simple but stricter than many buyers use. First, approve the pattern and measurement sheet. Second, approve material swatches for palm, back fabric, TPR hardness and closure. Third, review a pre-production sample in the final packaging method, because folded packing can distort the TPR shape. Fourth, set an inspection plan, commonly AQL 2.5 for major defects and 4.0 for minor defects on consumer-facing orders, with specific defect definitions for skewed TPR, open seams, delamination and left-right pairing mismatch. Carton planning matters too because TPR consumes volume. A packed impact glove takes noticeably more carton space than a flat PU-coated liner, so buyers should confirm pair-per-carton and carton dimensions before booking freight. For ocean shipments under FOB Ningbo or FOB Shanghai, this affects whether a mixed PPE order should move LCL or FCL. The production lead time for repeat mould styles is commonly around 35 to 50 days after deposit and final approval; for new mould projects, add the development window first. If the user environment is heavy oil, flash fire, chainsaw work or live electrical risk, be careful: a general synthetic leather TPR mechanic glove is usually the wrong platform, and a factory like ours would say so rather than force a bad match.
