In numerous fields—including aerospace, wind turbine blades, rail transit, sports equipment, electronic packaging, as well as rubber vulcanization and wood modification—the autoclave serves as the core process equipment for the curing, molding, and modification of composite materials. Traditional autoclave equipment often suffers from drawbacks such as low heating and temperature control precision, significant pressure fluctuations, poor sealing reliability, and inadequate operational safety safeguards. These deficiencies result in inconsistent product curing quality, elevated scrap rates, and even safety risks stemming from uncontrolled coupling between temperature and pressure increases.
Leveraging extensive engineering expertise in pressure vessels and thermal equipment, Tianmiao Chemical Machinery specializes in the design and manufacture of autoclaves. Through comprehensive enhancements spanning structural optimization, thermal and fluid field simulation, precision welding, and intelligent control systems, we provide safe, stable, and highly efficient complete autoclave systems for a wide range of high-temperature and high-pressure curing, impregnation, and processing applications.
Tianmiao autoclaves are available in both horizontal and vertical cylindrical configurations. Each unit is equipped with a complete suite of systems, including the vessel body, quick-opening door, thermal insulation, heating and pressurization mechanisms, circulation fans, vacuum cooling capabilities, and safety interlocks. The quick-opening door utilizes a clamp-ring or gear-locking mechanism, ensuring convenient operation and secure sealing; an integrated insulation layer effectively retains heat. The multi-mode heating system, combined with circulation fans, achieves uniform temperature control with a precision of ±1.5°C. Furthermore, the system features precise pneumatic pressurization, vacuum extraction of volatile components, and rapid cooling capabilities following the curing process.
The equipment offers a wide range of specifications—with diameters ranging from 600 to 5000 mm and lengths from 1000 to 20,000 mm—making it suitable for every scenario from small-scale R&D trials to full-scale mass production. With a design pressure range of 0.5 to 6.0 MPa and a maximum temperature resistance of 450°C, the equipment supports high-pressure customization requirements. Various material options are available on demand to suit standard, high-temperature, high-cleanliness, and highly corrosive operating environments. The insulation layer features a professional thermal design that maintains the external wall temperature at ≤50°C, demonstrating exceptional energy-saving performance. Our core process advantage lies in the utilization of an axial multi-nozzle airflow duct system paired with variable-frequency circulation fans. This system, integrated with a 3-to-9-point array of Type K thermocouples, achieves temperature control accuracy of ±1°C, thereby ensuring uniform temperature distribution throughout the vessel. High-precision pressure transmitters and control valves facilitate precise pressure regulation, allowing for the segmented configuration of pressurization and depressurization rates; at maximum operating pressure, the pressure drop remains ≤0.01 MPa/min, guaranteeing reliable sealing integrity. In strict compliance with GB 150 and TSG 21 standards, the system incorporates multiple safety interlocks to completely eliminate the risk of operational errors. Furthermore, the system integrates multiple process modes—supporting preset curing curves, slope control capabilities, and alternating vacuum/pressure cycles—to accommodate the diverse processing requirements of a wide range of materials.
Tianmiao autoclaves are categorized into three standard series, comprehensively covering the spectrum from R&D experimentation to large-scale industrial production. The Laboratory R&D Series features a compact footprint and comes standard with electric heating, air cooling, and an intelligent touch-control system; it supports data storage and export functions, making it ideally suited for new product prototyping in universities and research institutions. The Industrial Batch Production Series features moderate dimensions and offers a choice between steam or electric heating, complemented by automated loading and unloading fixtures; this series meets the demands of mass production applications such as wind power components, racing vehicle parts, and the winding and curing of high-pressure gas cylinders. The Large-scale Heavy Industry Series features massive dimensions and employs a multi-zone independent temperature control system, enabling it to handle the molding requirements of ultra-large-scale products—including aerospace skins, rocket fairings, marine composite structures, and large-scale rubber roller vulcanization.
Our company holds an A2-level manufacturing license for pressure vessels; consequently, our autoclaves are designed and manufactured in strict accordance with national standards such as GB 150, TSG 21, and GB/T 31117. All primary construction materials are sourced exclusively from reputable, large-scale steel manufacturers and undergo rigorous incoming inspection—including verification of material composition and mechanical properties—upon arrival at our facility. Welding operations are executed by certified welders in strict adherence to established procedures; process qualification tests have been successfully completed for all types of welded joints, and critical welds undergo 100% non-destructive testing. Upon completion, each unit undergoes a hydrostatic pressure test at 1.5 times its design pressure, followed by simultaneous air tightness and vacuum leak rate testing to ensure all performance metrics meet stringent quality standards. Each autoclave is delivered accompanied by a complete set of final documentation—including inspection reports and operation/maintenance manuals—ensuring full traceability and regulatory compliance throughout the entire lifecycle. The equipment features an ergonomic design, complete with a large-sized inspection manhole and internal walkways to facilitate routine maintenance; furthermore, the quick-opening door is fitted with durable seals that are easy to replace. Tianmiao provides comprehensive, full-lifecycle services—ranging from solution design, customized manufacturing, installation, and commissioning to operator training, after-sales support, and spare parts supply—and can promptly furnish professional equipment selection recommendations and complete system quotations upon request. The equipment ensures uniform and stable temperature and pressure control, thereby reducing product porosity and enhancing the consistency of mechanical properties; its intelligent, programmable control system for temperature and pressure can shorten the curing cycle by 15% to 30%. High-efficiency thermal insulation and energy-saving configurations reduce energy consumption by over 20%, while multiple safety interlocks—compliant with specialized equipment standards—ensure safe and reliable operation. This equipment is widely utilized across numerous industries, including aerospace, wind power, automotive, sporting goods, high-pressure gas cylinders, electronic potting, rubber vulcanization, and wood preservation.
