Established as part of the Jinwei Group with a heritage dating back to 1979, pioneering thermal solutions north of the Yangtze River.
Kingflex is established by Jinwei Group which boasts more than 45 years of history. Jinwei Group was established in 1979 as the very first manufacturer of thermal insulation materials north of the Yangtze River, laying the foundation for modern Chinese industrial insulation standards.
Our employees are exceptional on their own, but together they form a tightly-knit, highly talented group with a shared vision: delivering first-class service to global clients. Our R&D department features 8 professional engineers, backed by 6 international sales experts and 230 skilled production staff.
Kingflex operates 5 large-scale automatic assembly lines, yielding an annual production capacity exceeding 600,000 cubic meters. We are officially designated as a trusted production enterprise by the Ministry of Energy, the Ministry of Electric Power, and the Ministry of Chemical Industry.
Our mission is two-fold: supplying global clients with comprehensive energy-saving insulation system solutions, and serving as an integrated solution provider for thermal insulation, cold insulation, and noise reduction across building and industrial sectors.
Continuous innovation drives our product performance. Our state-of-the-art laboratory facilities enable rigorous testing for thermal conductivity, fire retardancy, and tensile strength under extreme operational parameters.
Deep-dive semantic research into high-temperature basalt wool production, thermodynamic efficiencies, and global industrial integration.
As global decarbonization mandates tighten, rock wool insulation board manufacturing is shifting toward electric furnace melting and zero-carbon emission binders. Future roadmaps prioritize nano-structured hydrophobic coatings, elevating service temperatures past 800°C while reducing thermal bridging in petrochemical and power generation facilities.
Our rock wool and elastomeric matrix solutions form complete thermodynamic barriers for mega-infrastructure projects. By combining closed-cell nitrile rubber for sub-zero HVAC condensation control with rigid rock wool boards for high-heat industrial boilers, Kingflex delivers turnkey thermal protection ecosystems.
Navigating international building codes requires stringent testing. Kingflex products comply with BS 476, CE, REACH, RoHS, UL94, and ASTM standards. Our engineering consultants offer regional code compliance audits, ensuring seamless customs clearance and structural approval.
Leveraging intelligent IoT-driven assembly lines, automated density scanning, and automated packaging, Kingflex guarantees batch-to-batch consistency. Our robust raw material reserves and logistics partnerships ensure uninterrupted global supply chain continuity.
Certified by global testing authorities, trusted by engineers and procurement heads across 88+ countries.
