Wholesale High Temperature Gloves Suppliers & Factory

Split cowhide is extracted from the fibrous reticular layer beneath the grain. It possesses high collagen fiber density, making it naturally resilient to heat shrinkage, direct flame, and spark penetration — the gold standard for heavy MIG, submerged arc, and stick welding (EN 12477 Type A). Goatskin, conversely, retains high natural lanolin levels and a tight grain surface. It provides remarkable tensile strength even when thinned down to 0.7mm – 0.9mm, conferring the micro-tactility indispensable for high-frequency TIG welding (EN 12477 Type B), where the welder needs to sense the cold wire feed with microscopic precision.

EN 407 measures distinct heat transmission vectors. Contact Heat tests the temperature (from 100°C up to 500°C) at which the glove interior remains below a 10°C rise for a minimum threshold of 15 seconds. Convective Heat assesses the time required to delay temperature rise inside the glove when directly immersed in an open flame. Radiant Heat measures the time required to achieve a given temperature rise when exposed to an intense infrared radiation source. A glove might resist 350°C contact heat via dense leather and fleece, but fail radiant tests without an aluminized heat-reflective outer backing.

Standard polyester, nylon, or cotton sewing threads soften and melt at temperatures between 160°C and 250°C. In heavy welding or foundry operations, hot sparks land inside seam grooves, instantly vaporizing synthetic threads and causing entire finger panels to burst open, exposing workers' bare hands. DuPont™ Kevlar® para-aramid thread does not melt, has no melting point, decomposes only above 427°C (800°F), and possesses five times the tensile strength of steel on an equal-weight basis, maintaining total seam integrity under extreme thermal shock.

Yes, over 80% of our production volume consists of OEM/ODM private-label manufacture for international safety brands and industrial distributors. We offer comprehensive branding customizations: heat-stamped leather branding, high-precision silk-screen printing, customized woven labels, full-color retail barcode hangtags, branded polybags, and custom export outer cartons with your unique SKU marks and pallets. We can execute production from your engineering tech packs or provide full reverse-engineering based on your reference sample.

For standard in-line leather welding gloves and accessories, our baseline MOQ is typically 1,200 to 2,400 pairs per style/size breakdown, which aligns with raw material hide batch tanning efficiencies. For specialized custom-tanned colors or unique composite fabrications, MOQs are confirmed on a project basis. Prototype sampling typically requires 7 to 10 working days. Mass bulk production lead time is approximately 40 to 45 calendar days following pre-production sample signoff and deposit clearance.

Our vertical integration is the key differentiator. Because we manage in-house leather re-tanning and finishing, every incoming hide lot is subjected to strict thickness micrometer verification across back, belly, and shoulder sections. Hides are segregated into tight 0.1mm tolerance bins prior to cutting. Furthermore, automated computer-controlled drum dyeing guarantees spectral color consistency across seasonal repeat orders. Our in-house QC team conducts tensile tear tests, pH chemical testing, and moisture content audits before hides ever enter the cutting room.

Absolute compliance. We strictly enforce European REACH Annex XVII standards across all leather and textile tanning operations. All finished products are certified free of prohibited Azo colorants, pentachlorophenol (PCP), and short-chain chlorinated paraffins (SCCP). Crucially for leather goods, we maintain total control over post-tanning oxidation inhibitors to ensure Hexavalent Chromium [Cr(VI)] content remains strictly non-detectable (below the 3 mg/kg laboratory detection limit according to EN ISO 17075).

Prior to shipping, our QC department executes an AQL 2.5 / 4.0 outgoing inspection, generating comprehensive photo and video audit reports covering stitching density, sizing measurements, barcoding, packaging integrity, and carton drop verification. Buyers or their designated third-party inspection firms (SGS, Bureau Veritas, Intertek) are welcomed into our Gaozhou factory. Our multilingual logistics desk coordinates directly with your freight forwarder for smooth booking at Shenzhen, Nansha, or Hong Kong ports, providing clean export documentation including Bill of Lading, Certificate of Origin, Packing Lists, and Commercial Invoices.
