Testing Chambers Knowledge

 How do you know if your products will survive the wear and tear of everyday use? If you’re a manufacturer, then this is something that’s important to you. You want to make sure that your product can withstand rough handling, extreme temperatures or harsh chemicals. The Temperature Aging Test Chamber by DGBELL provides an environment where accurate testing can be done on materials used in manufacturing processes for applications such as electronics, automotive parts, apparel and footwear. It is extremely durable with its stainless-steel body construction which makes it ideal for extended use in industrial environments. This chamber has been designed to simulate subjecting materials inside it to high levels of heat and humidity over time. Our test chamber has the ability to store up to two separate profiles at once. So, users are able to easily switch between different test runs without having any interruptions during their process.   Save money by eliminating field failure tes...

  The safety of lithium-ion batteries is our priority, especially in the fields related to the safety of our lives and property, such as passenger cars. In order to ensure the safety of lithium-ion battery, people have designed a variety of safety tests to ensure the safety of lithium-ion battery in case of abuse. Therefore, from the perspective of battery structure design optimization, how to pass this series of safety tests is a new problem that we need to consider. In view of the safety risks that lithium-ion batteries may encounter in practical use, we designed safety tests such as extrusion, acupuncture, short circuit, overcharge and discharge, high and low temperature. Among many safety tests, extrusion, acupuncture and external short circuit tests simulating internal and external short circuits of lithium-ion batteries are the most conventional and difficult to pass.  The main reason is that the instantaneous current in the two safety tests is too large. Due to ohmic im...

  You want to be sure that your new product can withstand rapid changes in temperature. Are you thinking about investing in a   thermal shock test chamber ?   We understand how difficult it is for businesses like yours to justify investing thousands of dollars on equipment that might not even work as well as an older model.   Our Thermal Shock Chamber meets and exceeds industry standards, so you can rest easy knowing your products will withstand rapid changes in temperature without breaking down. This will save you time and money by allowing your company to conduct more tests with fewer failures, which means less wasted resources from having to start over again with a new design every time something breaks during testing.   Three zones test c hamber can  enhance  thermal  shock  test  effect Thermal shock is one of the toughest tests that can be performed on electronic components. The term refers to a series of rapid, extreme temperature...

  Temperature and humidity control is critical in the testing of products. However, it can be tricky to control both at once. This article will show you how to use a   temperature cycling test chamber   with an integrated humidifier and dehumidifier so that you can keep your environment stable while still getting accurate readings on your product’s quality over time. A temperature cycling test chamber with an integrated humidifier and dehumidifier allows for more precise control of the environmental factors within a room than traditional methods like air conditioners or heaters alone. A properly calibrated TC will help ensure that your product performs as expected when used by customers in their homes or businesses – no matter what weather conditions they experience outside!   How to Operate a Temperature Cycling Test Chamber? 1.When the Temperature Cycling Test Chamber starts up, open the air inlet door (on the top), wait for 30 seconds before closing it. After thre...

  Poor air circulation can result in inaccurate temperature & humidity testing, which is why it’s important to have the right equipment. Air flow is one of the most critical components for a good   test chamber . If you don’t have enough air circulating around your samples, they could be subjected to hot or cold spots that skew results. The last thing you want are false positives or negatives because of poor airflow design. We’ve designed our chambers with stainless steel axial fans that provide rapid and uniform distribution across all surfaces inside the chamber. If your product is being tested for its ability to withstand high levels of moisture or water vapor, then you are going to need a professional chamber that can provide these conditions.   We have all the tools and expertise needed in order to create an environment where your products will be able to survive exposure to extreme amounts of moisture or water vapor.   Our facilities are specifically design...

  The selection of environmental and reliability test chamber shall follow the following five basic principles: 1. Reproducibility of environmental conditions It is out of reach to completely and accurately reproduce the environmental conditions existing in nature in the laboratory. However, within a certain tolerance range, people can accurately and approximately simulate the external environmental conditions experienced by engineering products in the process of use, storage and transportation. This paragraph is summarized in engineering language, that is, “the environmental conditions around the tested product (including platform environment) created by test equipment”  It shall meet the requirements of environmental conditions and their tolerances specified in the product test specifications “. Generally, according to the test quantities and test time of high temperature and low temperature specified for different types of products, it shall also meet the requirem...

  Purpose of environmental stress screening   The purpose of  environmental stress screening  is to find and eliminate the early failure of products, make them enter the random failure stage when leaving the factory, and deliver them to users with inherent reliability level.   Principle of environmental stress screening Environmental stress screening is to accelerate the internal potential defects into faults by applying reasonable environmental stress and electrical stress to electronic equipment, so that people can find and eliminate them.   Environmental stress screening is a technological means of equipment development and production. The screening effect depends on the applied environmental stress, electrical stress level and the ability of detection instruments. The magnitude of applied stress determines whether potential defects can be accelerated into faults within a predetermined time; The detection ability determines whether the potential defects ...

  Reliability test is an important technical means to evaluate and improve product reliability. It involves the formulation of test scheme, the development of test device, the recording of test process, the establishment of fault analysis technology and so on.   Purpose of Reliability Test Reliability test is a test to analyze and evaluate the reliability of products. By analyzing the test results, we can not only determine the reliability index of the product, but also analyze the failure of the product, find out its weak links, and take corresponding countermeasures to improve the reliability of the product. From the purpose, reliability test plays a very important role in studying the reliability of products   Characteristics of Reliability Test The reliability test is different from the routine test of the product. The purpose of the routine test is only to ensure that the parameters and physical and mechanical properties of the product meet the factory indicators dur...
