KRR AUTOCLAVES | PREPREG CURING SYSTEMS
Autoclave for Prepreg Curing
KRR Autoclaves designs and manufactures advanced composite curing autoclaves for prepreg parts used in aerospace, defence, UAV, R&D, automotive, motorsport and high-performance industrial applications. An Autoclave for prepreg curing is not just a pressure vessel; it is a controlled thermal-processing system where pressure, temperature, vacuum, air circulation, cooling and automation must work together to deliver repeatable laminate quality, low void content and consistent fibre-resin bonding.
Built with CSIR-NAL technology know-how and KRR’s heavy engineering capability, our systems are engineered for demanding composite manufacturing where accuracy, safety and process reliability are critical. From lab-scale development to large aerospace-grade production autoclaves, KRR provides complete, application-specific solutions designed around the customer’s part size, resin system, cure cycle, loading method, vacuum strategy and production requirement.
Autoclave for Prepreg Curing
Prepreg curing requires controlled heat-up rate, soak temperature, pressure ramping, vacuum holding, cooling rate and cure-cycle traceability. KRR autoclaves are designed to support these requirements through integrated heating, forced air circulation, vacuum lines, pressurization, cooling, PLC/SCADA automation, recipe management, alarms, interlocks and data logging.
The system ensures uniform temperature distribution across the working zone, stable pressure control during curing, reliable vacuum performance for bagged components and repeatable cure-cycle execution. This helps manufacturers achieve strong composite consolidation, reduced voids, improved surface finish and dependable mechanical performance in carbon fibre, glass fibre, hybrid composite and thermoset prepreg components.
Application

Vacuum bag curing, pressure-assisted consolidation, controlled heating and cooling, multi-zone temperature monitoring, recipe-based curing and batch reporting.
System scope
Autoclave vessel, door system, loading trolley, heating system, cooling system, vacuum system, pressurization system, instrumentation, automation, installation and lifecycle support.
Why KRR Autoclaves for Prepreg Composite Manufacturing
KRR combines pressure-vessel manufacturing strength, composite autoclave technology and automation capability under one roof. Our autoclaves are engineered for long service life, operator safety and production repeatability, with configurations available up to large diameters, long lengths, high pressure and high temperature requirements.
Every project is designed based on the customer’s actual prepreg process, not as a generic machine. We study part geometry, material system, curing temperature, pressure requirement, vacuum points, loading method, heat uniformity expectations, control philosophy and future expansion needs before finalizing the system.
