Product Usage
The Horizontal Cold and Hot Shock Test Chamber is used to evaluate the ability of material structures or composite materials to withstand rapid alternating exposure to extremely high and low temperatures. It tests the chemical and physical damage caused by thermal expansion and contraction within a very short time. The sample remains completely stationary during testing, which is the current standard method for electronic component testing, research applications, and large-scale screening in semiconductor production lines. This approach significantly reduces material consumption and testing costs. It features fast operation and high reliability. Suitable for testing metals, plastics, rubber, electronics, aerospace materials, and more.
