Kingflex Insulation Co., Ltd. is a leading professional manufacturing and trading combo for thermal insulation systems. Based in Dacheng, China—widely recognized as the green-building materials capital—our facility represents an energy-saving, environmentally responsible enterprise that concentrates on research and development, strict quality production, and global sales outreach.
Driven by the core values of energy conservation and consumption reduction, Kingflex is more than a manufacturer. We serve as an integrated partner providing complete consulting, custom R&D development, precision manufacturing, local installation guidance, and dependable post-sale services. We lead innovation within the global construction, industrial process pipe, and building efficiency sectors.
Founded by the renowned Jinwei Group (Kingway Group), our origins stretch back to 1979. Boasting over 40 years of engineering legacy, Jinwei Group established itself as the pioneer manufacturer of thermal insulation materials north of the Yangtze River.
Leveraging this rich structural heritage, Kingflex has modernized process manufacturing for high and low temperature applications alike. Today, we bridge legacy engineering principles with AI-informed process automation to deliver maximum efficiency at scale.
With global net-zero targets drawing closer, industrial processes must limit radiant energy losses. High-performance insulation helps facilities minimize thermal dissipation, optimizing fuel use in steel, chemical processing, and energy generation sectors.
From LNG transport systems operating at -162°C to steam process systems exceeding hundreds of degrees, modern piping requires robust thermal resistance. Dual-temperature insulation reduces condensation and controls energy flow across varying operational cycles.
Minimizing structural fire risks and protecting personnel from hot surface exposure is vital. Our materials prevent moisture-induced corrosion (CUI) while meeting strict international fire rating codes (e.g., BS 476, ASTM, UL 94).
Selecting appropriate industrial insulation requires analyzing temperature variations, external mechanical stress, environmental moisture levels, and chemical exposures. High-density elastomeric rubber foams and specialized rock wool configurations offer reliable protection for challenging processing environments.
Kingflex operates five fully automated production lines, ensuring consistent density and cell structure. We meet the rigorous requirements of global industrial suppliers.
Our operation features 8 dedicated R&D development engineers, 6 experienced international sales advisors, and 230 technicians. Designated as an approved insulation manufacturer by major energy and chemical ministries, Kingflex guarantees project compliance and reliable supply chains.
Our sheet insulation provides thermal control, acoustic dampening, and moisture resistance. The closed-cell structure blocks moisture vapor pathing to prevent pipeline corrosion.
