• Lab Industrial High-Temperature Aging Oven

  Nov 05, 2025

  An industrial high-temperature aging oven is a device that conducts accelerated aging tests on industrial products (such as electronics, electrical appliances, components, chemical materials, etc.) by simulating high-temperature environments. By applying high-temperature stress, potential defects and faults of the products can be exposed in advance, thereby screening out early-failed products and enhancing the reliability and stability of the products leaving the factory. Its core components mainly include the heating system, circulation system, control system and safety protection system.   Main features: Firstly, it has a wide operating temperature range, typically from room temperature +10°C to +200°C or 300 °C. Temperature uniformity is a key indicator for evaluating the performance of an oven. The temperature difference at each point inside the oven is ±2°C, and the temperature control accuracy usually reaches ±0.1°C to ±1°C, ensuring the precision and repeatability of the test conditions. In addition, the heating rate can be set according to the test requirements, ranging from linear heating to rapid heating. The internal structure of the test chamber is usually made of stainless steel (such as SUS304), which is heat-resistant and corrosion-resistant. The shell is generally made of high-quality cold-rolled steel plate and the surface is treated with plastic spraying. Finally, the insulation layer is usually made of high-density aluminosilicate cotton or rock wool, with sufficient thickness to ensure that the surface temperature of the box is low and energy-saving. The air duct is designed for horizontal or vertical air supply to ensure that the hot air can flow evenly through each product under test.   Aging ovens are widely used in all industries that have high requirements for product reliability: Electronics industry: IC chips, PCB circuit boards, power supplies, chargers, LED displays/lamps, automotive electronics, etc. Electric appliances: transformers, relays, capacitors, circuit breakers, motors, etc. Communication products: mobile phones, routers, base station equipment, optical modules, etc. Chemical materials: Conduct high-temperature aging resistance tests on coatings, plastics, rubbers, adhesives, etc. Automotive parts: various sensors, controllers (ECUs), wiring harnesses, etc.   How to choose the right industrial high-temperature aging oven? When making a choice, the following factors need to be comprehensively considered: 1. Temperature range: According to the product testing standards, select the model that can meet the highest and lowest temperature requirements, and leave a certain margin. 2. Inner box size: Select an appropriate volume based on the size and quantity of the products to be tested. Remember to reserve space to ensure air circulation. 3. Temperature uniformity and accuracy: The higher the requirements, the higher the equipment cost and manufacturing difficulty. Choose according to the strictness of the test. 4. Load condition: If the product will generate heat by itself during the testing process (i.e., "load testing"), it is necessary to inform the equipment manufacturer so that they can calculate and configure sufficient heating and heat dissipation capacity. 5. Control System and Functions: Is program control (multi-stage temperature rise and heat preservation) required? Is it necessary to record and export the temperature curve data? Whether remote monitoring and other factors are needed Industrial high-temperature aging ovens are an indispensable part of modern quality engineering. Through sample aging tests, it intercepts potential faulty products before they leave the factory, significantly reducing the market return rate and after-sales maintenance costs, and earning credibility and long-term benefits for the enterprise. When making a purchase, you can communicate fully with us based on the characteristics of your own products and testing requirements, and choose the most suitable solution.

• Lab Aging Test Chamber Working Principle

  Oct 17, 2025

  Many products (such as rubber, plastic, insulating materials, electronic components, etc.) will age due to the combined effects of heat and oxygen when exposed to the natural environment over a long period of use, such as becoming hard, brittle, cracking, and experiencing a decline in performance. This process is very slow in its natural state. The air-exchange aging test chamber greatly accelerates the aging process by creating a continuously high-temperature environment and constantly replenishing fresh air in the laboratory, thereby evaluating the long-term heat aging resistance of materials in a short period of time.   The working principle of Lab aging test chamber mainly relies on the collaborative efforts of three systems: 1. The heating system provides and maintains a high-temperature environment inside the test chamber. High-performance electric heaters are usually adopted and installed at the bottom, back or in the air duct of the test chamber. After the controller sets the target temperature (for example, 150°C), the heater starts to work. The air is blown through the heater by a high-power fan. The heated air is forced to circulate inside the box, causing the temperature inside the box to rise evenly and remain at the set value. 2. The ventilation system is the key that distinguishes it from ordinary ovens. At high temperatures, the sample will undergo an oxidation reaction with oxygen in the air, consuming oxygen and generating volatile products. If the air is not exchanged, the oxygen concentration inside the box will decrease, the reaction will slow down, and it may even be surrounded by the products of the sample's own decomposition. This is inconsistent with the actual usage of the product in a naturally ventilated environment. 3. The control system precisely controls the parameters of the entire testing process. The PID (Proportional-integral-Derivative) intelligent control mode is adopted. The real-time temperature is fed back through the temperature sensor inside the box (such as platinum resistance PT100). The controller precisely adjusts the output power of the heater to ensure that the temperature fluctuation is extremely small and remains stable at the set value. Set the air exchange volume within a unit of time (for example, 50 air changes per hour). This is one of the core parameters of the air-exchange aging test chamber, which usually follows relevant test standards (such as GB/T, ASTM, IEC, etc.).   The test chamber creates a high-temperature environment through electric heaters, achieves uniform temperature inside the box by using centrifugal fans, and continuously expels exhaust gases and draws in fresh air through a unique ventilation system. Thus, under controllable experimental conditions, it simulates and accelerates the aging process of materials in a naturally ventilated thermal and oxygen environment. The biggest difference between it and a common oven lies in its "ventilation" function, which enables its test results to more truly reflect the heat aging resistance of the material during long-term use.

• Resumen de las condiciones de prueba de LED

  Apr 22, 2025

  ¿Qué es un LED? Un diodo emisor de luz (LED) es un tipo especial de diodo que emite luz monocromática y discontinua al aplicar una tensión directa, un fenómeno conocido como electroluminiscencia. Al alterar la composición química del material semiconductor, los LED pueden producir luz ultravioleta cercana, visible o infrarroja. Inicialmente, los LED se utilizaban principalmente como luces indicadoras y paneles de visualización. Sin embargo, con la llegada de los LED blancos, ahora también se emplean en aplicaciones de iluminación. Reconocidos como la nueva fuente de luz del siglo XXI, los LED ofrecen ventajas incomparables, como alta eficiencia, larga vida útil y durabilidad, en comparación con las fuentes de luz tradicionales. Clasificación por brillo: LED de brillo estándar (fabricados con materiales como GaP, GaAsP) LED de alto brillo (fabricados con AlGaAs) LED de brillo ultraalto (fabricados con otros materiales avanzados) ☆ Diodos infrarrojos (IRED): emiten luz infrarroja invisible y sirven para diferentes aplicaciones.   Descripción general de las pruebas de confiabilidad de LED: Los LED se desarrollaron por primera vez en la década de 1960 y se utilizaron inicialmente en señales de tráfico y productos de consumo. Solo en los últimos años se han adoptado para la iluminación y como fuentes de luz alternativas. Notas adicionales sobre la vida útil del LED: Cuanto menor sea la temperatura de unión del LED, mayor será su vida útil, y viceversa. Vida útil del LED a altas temperaturas: 10.000 horas a 74 °C 25.000 horas a 63 °C Como producto industrial, las fuentes de luz LED deben tener una vida útil de 35.000 horas (tiempo de uso garantizado). Las bombillas tradicionales suelen tener una vida útil de unas 1.000 horas. Se espera que las farolas LED duren más de 50.000 horas.
