  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.

• Customized Solution for Double-Door Temperature Test Equipment

  Oct 25, 2025

  1.Core customization requirement analysis 1.1 The standard box size or load-bearing capacity (such as automotive parts, large unmanned aerial vehicles, and entire cabinet servers) cannot meet the requirements. Special sample racks, trays or suspension devices are required. The test samples need to be powered on and run inside the box, and connected to cables or pipes (such as battery pack charge and discharge tests, engine component tests). Oil stains, particulate matter or corrosive gases may be released during the sample testing process. 1.2 It needs to be connected with mechanical arms and AGV carts to achieve automatic loading and unloading. The heating and cooling rates required far exceed the standard specifications (such as >15°C/min). 1.3 The equipment needs to adapt to specific room sizes, door opening sizes or floor heights. There are special requirements for the power supply (if it cannot meet 380V) and the cooling water source (if a cooling tower cannot be provided).   2. Key customized technical specifications 2.1 Customized Dimensions The internal effective space is determined entirely based on the size and quantity of the customer's samples. The minimum distance between the sample and the box wall needs to be considered to ensure uniform airflow. It is necessary to clearly define the size of the door, the material of the sealing strip, the door lock mechanism (mechanical lock, pneumatic auxiliary lock), and the size and quantity of the observation window. The inner box is usually made of SUS304 stainless steel. The outer box body can be made of high-quality steel plate with plastic spraying or SUS304. For corrosive tests, more durable materials should be specified. Test holes are used for leads. The size, quantity and position of the hole diameters (such as left or right) need to be customized, and sealing plugs or flanges should be provided. 2.2 Confirm the test interval The technical index standards for temperature are usually from -70°C to +150°C. The standard heating and cooling rate is 1 to 3°C/min. Linear rapid temperature change: 5 to 10°C/min. Nonlinear rapid temperature change: Customizable to 15°C/min or even higher. This is directly related to the power configuration of the refrigeration and heating systems and is a key factor influencing the cost. Customize stricter control accuracy, such as uniformity ≤±1.0°C and fluctuation ≤±0.5°C. 2.3 Refrigeration System Air cooling: Suitable for sites where the ambient temperature is not high and the ventilation around the equipment is good. Water cooling: It is suitable for large cooling capacity, high heat generation samples, or situations with high ambient temperatures. It is more efficient but requires a cooling tower. Cascade refrigeration: It is used for low-temperature requirements below -40°C and usually adopts two-stage cascade. 2.4 Installation Method The refrigeration system of the integrated machine is located at the top or bottom of the box, with a compact structure and convenient installation. The split-type refrigeration unit is separated from the box body and is suitable for high-power equipment. It can discharge noise and heat to the outside, but the installation is complex. 2.5 Control System and Software The controller customizes the size and brand of the color touch screen, supports multi-segment programming, program group loops, step jumps, etc. Customized LAN interface for connecting to the upper computer (computer) for data monitoring and recording. Whether it is necessary to support remote network monitoring and operation, as well as customize record intervals and storage capacity. 2.6 Independent sample over-temperature protector. Compressor overheat, overcurrent and overpressure protection; Fan overcurrent protection Cooling water cut-off protection and automatic stop test function when the door is opened; Leakage or short-circuit protection; Sound and light alarm prompt.   Customizing double-door temperature test equipment is a systematic project. The key to success lies in the clarification and refinement of the initial requirements. A detailed and unambiguous "Technical Requirements Document" serves as the cornerstone for communication between equipment suppliers and customers. It ensures that the final delivered equipment fully complies with testing, process, and site requirements, avoiding subsequent disputes and cost overruns.

• The Function of Adding Nitrogen Input to Industrial Ovens

  Oct 14, 2025

  The core function of adding nitrogen input in industrial ovens is to create an inert atmosphere environment with low oxygen or no oxygen. This is usually referred to as "nitrogen protection" or "nitrogen-filled baking".   Preventing oxidation is the most common and primary purpose. When heated in the air (with an oxygen content of approximately 21%), many materials will undergo oxidation reactions, thereby affecting product quality. Adding nitrogen input to industrial ovens can prevent the formation of oxide scale (such as rust) on the surface of metal products during heating, keep the metal bright and clean, and improve the quality of subsequent processes such as electroplating and spraying. Or to prevent the oxidation of component pins, pads and precision films at high temperatures, ensuring the quality of soldering and the long-term reliability of the product. At the same time, it can also prevent chemical and powder materials from undergoing chemical reactions with oxygen at high temperatures, thereby altering their chemical properties. 2. Some materials pose a risk of fire or explosion in high-temperature and oxygen-rich environments. Increasing nitrogen input can suppress combustion and explosion. In industries such as printing and coating, a large amount of flammable organic solvents (such as alcohol, acetone, and toluene) are volatilized during the baking process. Introducing nitrogen to reduce the oxygen concentration below the limit oxygen concentration can completely eliminate the risk of fire and explosion, which is an important safety measure. For metal and plastic powders, when they reach a certain concentration in the air, they are highly prone to explosion when exposed to open flames or high temperatures. Nitrogen protection can create a safe processing environment. 3. Improve process control and product quality. Heating in an oxygen-free or low-oxygen environment can avoid many side reactions caused by oxygen. In processes such as chip manufacturing and solar cell production, extremely high cleanliness and an oxygen-free environment are essential to prevent the oxidation of silicon wafers, metal electrodes, etc., ensuring extremely high product yield and performance. 4. While filling the oven with nitrogen, the air that originally contained moisture and oxygen inside the oven will also be "driven out". This not only prevents oxidation but also plays an auxiliary drying role, making it particularly suitable for products that are extremely sensitive to moisture.   In conclusion, adding nitrogen input to industrial ovens is to actively control the heating environment rather than passively heating in the air. This is an important technical means used in high-end manufacturing and precision processing.

• المكنسة الكهربائية أولا ، ثم التسخين: التشغيل السليم لفرن التجفيف

  Feb 28, 2025

  لماذا يجب أن تم إخلاءها قبل التسخين في فرن تجفيف الفراغ？ 1) حماية مضخة الفراغ ：إذا قمت بتسخين الفرن قبل الإخلاء ، فسيتم رسم الهواء المسخن بواسطة مضخة الفراغ. تنقل هذه العملية الحرارة إلى المضخة ، مما قد يتسبب في ارتفاع درجة الحرارة. يمكن أن يؤدي ارتفاع درجة الحرارة إلى تقليل كفاءة مضخة الفراغ وقد تتلفها. 2) منع الأضرار التي لحقت مقياس الفراغ:إذا كان تسخين الفرن أولاً ، فسيوجه الهواء المسخن نحو مقياس الفراغ ويتسبب في ارتفاع درجة حرارة هذه الأداة. إذا تجاوزت درجة الحرارة الحدود التشغيلية للمقياس ، فقد يؤدي ذلك إلى قراءات غير دقيقة أو أضرار دائمة. 3) تجنب مخاطر السلامة:يتم وضع المادة المختبرة في غرفة الفراغ التي يمكنها إزالة الغازات المستخرجة من المادة. إذا تم تسخين المادة التي تم اختبارها أولاً ، فسيتوسع الغاز عندما يواجه الحرارة. بسبب الختم الممتاز للغرفة الفراغية ، يمكن أن يؤدي الضغط الهائل الناتج عن الغاز المتسع إلى تحطيم الزجاج المقسى في نافذة المراقبة. الإجراء الصحيح هو إخلاء الهواء أولاً ثم الحرارة. إذا انخفض مستوى الفراغ بعد الوصول إلى درجة الحرارة المطلوبة ، فيمكنك إعادة التوجيه لفترة وجيزة. تساعد هذه الطريقة على تمديد عمر المعدات. خاتمة:لضمان السلامة ، والحفاظ على كفاءة المعدات ، وإطالة عمر فرن تجفيف الفراغ ، اتبع دائمًا الإجراء الصحيح: إخلاء الهواء أولاً ، ثم الحرارة. هذه الخطوة البسيطة يمكن أن تمنع المخاطر المحتملة والأضرار المكلفة.
