Thermal shock chambers are used to replicate the conditions of sudden and drastic changes in temperature in order to test the capability of a product, material or part component to withstand the resulting stress and strain. Environmental chambers evaluate product quality and reliability, and identify manufacturing flaws and weaknesses in those products before they are released to the general market, or used in the manufacturing of other products.
Industries such as consumer, medical, automotive, aerospace and construction use thermal shock chamber testing to ensure the reliability of their products. Thermal shock causes cracking or faulting along lines of stress as a result from the conflict between uneven element expansion and compression according to relative temperature. As one section cools or heats faster than another, the pressure placed on a material becomes greater than the strength of that material and a crack is formed. These cracks can be severe enough to cause structure failure. Glass and ceramics are particularly susceptible to thermal shock damage due to their low thermal conductivity and their tendency to expand and compress unevenly, and so test chambers are an important part of the manufacturing process for products and structures using these materials.
