What Hengko does

HENGKO Technology Co., Ltd. is a Shenzhen, China-based private manufacturer founded in 2001 that produces two product lines: sintered porous metal filters (discs, tubes, plates, cups, mesh, spargers, cartridges) made from stainless steel 316L powder and multilayer wire mesh with controlled pore sizes of 0.2-120 microns; and industrial temperature/humidity/dew point transmitters, probes, handheld meters, and sensor housings with RS485, 4-20mA, 0-5V, and 0-10V outputs. The company's underlying technology is powder metallurgy sintering combined with industrial humidity sensing, with materials including SS304, SS316L, 904L, Titanium, and Hastelloy, and operating ranges from -20°C up to 300°C. Recent 2025 launches include a 200°C-rated humidity sensor for flue gas and drying applications, a sintered in-line gas filter for semiconductor purification, and one-way valves for bronchoscopic lung volume reduction medical devices.

HENGKO operates an OEM-embedded go-to-market, selling direct to engineering and procurement teams at industrial OEMs, laboratories, and equipment manufacturers. Pricing is quote-based, factory-direct with no middleman, and revenue is generated through one-time customized hardware sales for industrial filtration, gas-liquid mass transfer, and process monitoring applications. The company serves seven primary vertical segments (biotech/pharmaceutical, semiconductor, industrial HVAC/building automation, food and beverage, water treatment, pneumatic equipment, and consumer/prosumer), and exports to 65+ countries, with a marquee customer base including Procter & Gamble, Honeywell, Emerson, Foxconn, CRRC, CASC, Solvay, and WuXi AppTec.

The company is privately held with no disclosed outside funding; the operating basis is a 101-250 employee Shenzhen headquarters with multilingual marketing infrastructure (40+ language site versions). Scale claims include 30,000+ projects served, 100,000+ customized products supplied, and CE/SGS certifications enabling global industrial distribution.
