What Can You Achieve with JCT High-Temp Chambers?
Our high-temp chambers execute strict industrial testing protocols. Using them, you can bake trapped moisture out of PCBs to prevent delamination during reflow soldering, sustain rubber gaskets at 200℃ to test long-term embrittlement, or push structural alloys to 700℃ to find their absolute physical failure points. We provide the exact thermal data you need to eliminate design flaws before mass production
Accelerated Thermal Aging
What it does: Sustaining rubber gaskets, plastic housings, and cable insulation at a constant 200℃ or 300℃ for hundreds of hours, replicating years of severe operational heat in a matter of days.
The Benefit: Pinpoints the exact timeline of material embrittlement and elasticity loss. This hard data allows you to accurately calculate MTBF (Mean Time Between Failures) and replace weak materials before they cause cracked seals and leaks in the field.
Moisture Bake-Out & Stress Relief
What it does: Using precise thermal profiling to slowly and safely extract trapped moisture from hygroscopic PCBs, microchips, and epoxies right before they enter the high-heat assembly line.
The Benefit: Completely eliminates the “popcorning” effect—where trapped moisture rapidly vaporizes, expands, and shatters the board during reflow soldering. This directly prevents board delamination and drastically reduces your manufacturing defect rate.
Thermal Destruction & Phase Change
What it does: Subjects advanced composites, ceramics, and structural alloys to extreme 500℃ or 700℃ environments to force severe oxidation, structural phase changes, and ultimate material breakdown.
The Benefit: Identifies the absolute physical failure point of your components. This guarantees that critical parts—as like automotive engine shields or aerospace housings—will not melt, warp, or fail under peak operational thermal loads

Applications
pcb fabrication manufacturer
Epoxies and microchips naturally absorb atmospheric moisture. If this moisture is not removed before the high-heat reflow soldering process, it vaporizes instantly, causing the board to crack and delaminate (the “popcorning” effect). Using our HT series high temperature chamebers for a slow, controlled 150℃ moisture bake-out completely eliminates this risk, drastically improving your SMT assembly yield rates
rubber seal
Hydraulic fluids and industrial pressures destroy weak seals. By sustaining rubber seals and gaskets hoses at a constant 200℃ for 72+ hours, our JCT high temperature chambers accelerate the natural thermal aging process. This hard data allows you to accurately pinpoint the timeline of material embrittlement and elasticity loss, ensuring your seals will never leak under prolonged industrial stress.
automotive industry
The area surrounding an engine exhaust manifold experiences extreme radiant heat. Automotive plastics, wire harnesses, and sensors must be tested at 300℃ in our JCT-MHT series to validate their endurance. We help you verify that critical under-hood components will not melt, warp, or catch fire during peak engine loads in heavy traffic conditions.
aerospace components manufacturing
Advanced carbon fibers and heat-shield resins face intense aerodynamic friction at high altitudes. Pushing these materials into our JCT 500℃ UHT chamber series chambers exposes critical structural vulnerabilities.For aerospace components manufactures,please Verify that your aerospace composites retain their tensile strength and do not undergo dangerous physical phase transitions when exposed to extreme atmospheric friction
casting foundry
New metal alloys must be pushed to their absolute thermal destruction limits, before being casted into engine blocks or structural beams. Our JCT- UUHT series safely generates 700℃ environments to analyze surface oxidation layers and decarbonization rates. This provides metallurgists with the exact safety thresholds ,which are needed to prevent catastrophic mechanical failures
ev battery
EV safety relies entirely on the internal EV Battery Separator Films . If this film shrinks under heat, the anode and cathode touch, resulting an instant thermal runaway and explosion. We heat these lithium-ion separator films to 150℃-200℃ by our JCT high temperature chambers to precisely measure their heat shrinkage rate. Passing this test is non-negotiable for electric vehicle battery certification and ultimate passenger safety.

FAQ
Q1: What is the difference between a standard industrial oven and a high-temperature test chamber?
Standard ovens lack precision control and use weak airflow, leading to massive temperature imbalances (often >10℃ variation).
By Our high-temperature chambers ,you can utilize precision PID controllers and forced horizontal airflow to guarantee a strict ±2.0℃ uniformity, providing the highly repeatable data required for GB, IEC, and MIL certifications.
Q2: How do I choose between the HT, MHT, UHT, and UUHT series?
Choose JCT-HT test chamber(200℃) for basic plastic and rubber aging;
JCT-MHT test chamber (300℃) for automotive and under-hood electronics endurance;
JCT-UHT test chamber (500℃) for aerospace phase-changes;
JCT-UUHT test chamber (700℃) for metallurgy oxidation and thermal destruction limits.
Q3: How do I determine the right chamber volume (Liters) for my payload?
Never pack a test chamber 100% full. To make sure optimal airflow and temperature uniformity, your test specimens should only occupy 30% to 50% of the internal volume. If you have large batches, we highly recommend upgrading from our 216L models to our 512L or 1000L heavy-duty systems.
Q4: Do you provide data export functions for quality audits?
Yes. The smart controllers allow you to export real-time temperature logs and thermal curves directly via USB or RS485 connections. This will supply you instant, traceable testing reports ready for the third-party quality audits.
