冷热冲击试验机，用来测试材料结构或复合材料，在瞬间下经温及极低温的连续环境下所能忍受的程度，藉以在最短时间内试验其热胀冷缩所引起的化学变化或物理伤害。适用的对象包括金属，塑料，橡胶，电子等材料，可作为其产品改进的依据或参考。
Thermal Shock Chamber  is used to test the capability of material structure or composite materials to withstａnd the continuous environmental changes between extremely high temperature and low temperatures during a short period, and therefore understａnd the chemical changes or physical damages caused by expansion from heat and contraction from cold in the shortest possible time. It is applicable to metals, plastic, rubber, electronics amongst other materials. The test result can be used as a reference or basis for product improvement.
