Since 2003, MEC ADDHEAT has dedicated itself to the R&D and advanced manufacturing of battery-powered wearable thermal systems. As a true pioneer in smart warming technology, we vertically integrate and manufacture all core components in-house—including precision NTC controllers, flexible heating modules, and high-safety battery packs. By maintaining 100% engineering authority over every process, we deliver uncompromised safety, constant innovation, and absolute supply chain reliability.
Powered by over 400 skilled professionals, our modern facilities deliver a monthly output exceeding 200,000 thermal modules. Unlike traditional piece-rate factories that sacrifice quality for speed, we operate on a fixed hourly wage system. This prioritizes worker well-being, workplace safety, and meticulous precision over rushed quotas. Driven by lean JIT scheduling and high-precision automation, every module is crafted with ultimate care and structural consistency.
Backed by rigorous lab validations—including automated testing that guarantees over 95% thermal efficiency retention even after 50 wash-and-dry cycles—our heating systems achieve industry-lowest defect and return rates (<0.1%). Fully certified under major global standards (UL, CE, FCC, RoHS), our user-centric designs elevate the end-consumer experience while serving as an unshakeable shield for your brand’s market reputation.
Trusted by over 50 premier apparel, outdoor, and technical gear brands across North America, Europe, and Asia, we build long-term strategic alliances—never one-off transactions. While we operate behind the scenes, we view your consumers’ safety and satisfaction as our own. Serving as your reliable manufacturing backbone, we empower our B2B partners to win market share and build maximum customer loyalty.
The ultimate test of technology isn’t just winning medals, but delivering everyday comfort and reliability to end users. Powered by ultra-thin flexible heating elements and smart temperature control, our garments consistently earn top ratings for rapid warmth, lightweight mobility, and long-lasting durability in real-world winter conditions.
