Temperature humidity environmental chamber, also called climatic chamber, is a common environmental simulation system and device in laboratories and factories. Environmental chambers are used to test the performance stability of materials or products in various environments by simulating natural environments such…
COVID-19 has been going on for roughly two years now. In the face mask market, from the initial shortage of supply to the current basic balance between supply and demand, it will be increasingly important to reduce costs and improve…
In the manufacturing industry, the stability of products under various temperature and humidity conditions is the key to quality control. Temperature humidity chamber is one of the most common environmental control instruments that can quickly test the performance stability of…
Measurement is essential in all kinds of physical experiments and technology development processes, and as long as the measurement result, measurement error is inevitable. The error affects measurement accuracy, so the technical staff concerned must learn and master the theory…
The properties of a material in terms of deformation and damage under tensile forces can be measured by the tensile stress-strain curve, which is one of the most fundamental and important concepts in the mechanics of materials, come with me…
Although the electronic universal testing machine and hydraulic universal testing machine belong to the mechanical test equipment, but because of the two in the drive power source, the main body structure, and the application of scalability has a large difference,…
Tensile testers, also known as electronic tensile testing machines, can be used for various materials for tensile, compression, bending, shear, tearing, peeling, and other mechanical performance tests. Due to the powerful function and wide range of applications of the tensile…
