Advanced Convection Furnaces for Aerospace Heat Treatment and Precision Thermal Processes
KEPKA designs and delivers high-precision convection furnaces dedicated to aerospace manufacturing, where temperature accuracy, process repeatability and strict compliance with material standards are mandatory. Our systems support critical heat treatment and thermal conditioning processes for aluminum alloys, titanium alloys and high-performance aerospace components.
A key part of our aerospace portfolio includes drop-bottom convection furnaces with dynamic, turbulent airflow and integrated rapid cooling systems, engineered for solution heat treatment and subsequent quenching of aluminum alloys used in structural aircraft components.
Drop-Bottom Convection Furnaces for Aluminum and Aerospace Alloys
KEPKA drop-bottom furnaces are designed for solution heat treatment of aluminum alloys, followed by rapid and controlled cooling. The drop-bottom design allows immediate transfer of components from the heating chamber to the quenching zone, minimizing delay and ensuring compliance with aerospace process requirements.
Dynamic, turbulent airflow inside the chamber guarantees uniform temperature distribution across complex geometries, large structural parts and thick-walled components. This uniformity is essential to achieve consistent metallurgical properties, reduce distortion and ensure repeatable mechanical performance.
The combination of precise convection heating and fast quenching enables KEPKA furnaces to meet demanding aerospace process windows, where even small temperature deviations can compromise material properties.
AMS Compliance
and Aerospace Process Standards
KEPKA aerospace furnaces are engineered to support processes compliant with AMS (Aerospace Material Specifications), including requirements for:
- temperature uniformity,
- controlled heating rates,
- defined soaking times,
- rapid transfer and quenching conditions,
- traceable and repeatable process execution.
Advanced control systems provide full recipe management, data logging and process traceability, supporting qualification and audit requirements typical in aerospace production environments.
Convection Furnaces for Precision Rotor and Shaft Fitting
Beyond aluminum heat treatment, KEPKA supplies high-temperature convection furnaces for precision thermal processes such as shrink fitting and thermal fitting of aerospace components. These furnaces are used for controlled heating of:
- turbine rotors,
- turbine shafts,
- bearing seats and assemblies,
- rotating components requiring tight dimensional tolerances.
Operating at temperatures exceeding 900°C, these systems enable precise expansion of components without inducing thermal stress or surface damage. Uniform convection airflow ensures stable and predictable dimensional changes, allowing safe and accurate assembly of critical rotating parts used in turbine engines and aerospace propulsion systems.
High-Precision Thermal Control and Dynamic Airflow
All KEPKA aerospace furnaces are built around dynamic, turbulent convection airflow, designed to eliminate temperature gradients and dead zones within the working chamber. Multi-zone heating architecture allows fine shaping of thermal profiles, ensuring that every component experiences identical conditions regardless of position or load configuration.
This level of control is critical for aerospace materials, where consistency, repeatability and material integrity directly affect flight safety and long-term performance.
Summary
KEPKA aerospace thermal systems combine drop-bottom convection furnace design, rapid quenching, high-temperature capability above 900°C, and AMS-compliant process control to support the most demanding aerospace applications. From solution heat treatment of aluminum alloys to precision thermal fitting of turbine rotors and shafts, our furnaces provide the accuracy, reliability and traceability required in modern aerospace manufacturing.
