The difference between two boxes and three boxes of high and low temperature impact test boxes

Abstract: The hot and cold impact test chamber is an indispensable test equipment for metal, plastics, rubber, electronics and other materials industries. It is used to test the structure of materials or composite materials, and tolerate it under extremely high temperature and extremely low temperature in a continuous environment. The chemical change or physical damage caused by thermal expansion and contraction of the sample can be detected in the shortest time.

Cold and hot red low temperature test box is also called high and low temperature impact test box, used in electronic and electrical components, automation parts, communication components, auto parts, metal, plastic and other industries, defense industry, aerospace, military industry, electronic chip IC, The physical changes of semiconductor ceramics and polymer materials, the repeated resistance of high and low temperature materials, and the chemical changes or physical damages produced by thermal expansion and contraction of the materials can be tested to confirm the quality of the products, from the precision of the IC to the weight None of the mechanical components need its ideal test tool. At present, there are two kinds of high and low temperature impact test boxes that are produced and sold on the market. Two boxes and three boxes are available! These two kinds of impact test boxes have their own characteristics, each with its advantages.

The three-box impact box has three boxes, a high temperature box, a box for placing products, and a low temperature box. When the high temperature is tested, the high temperature box door is opened and the low temperature box door is closed. Similarly, when the low temperature is measured, the high temperature door is closed and the low temperature door is opened. The two-box cold and hot shock test box has two boxes, a high temperature box and a low temperature box, and the middle is a hanging basket. When the product is tested, it is placed in the basket and the basket is referred to the high temperature box when doing the high temperature test. Otherwise, the low temperature test is performed.

Analysis of performance characteristics

Two boxes:

1. The sample is rapidly placed in a pre-cooled low-temperature room or a pre-heated high-temperature room, so the temperature change is fast;

2, compact structure, small size;

3, the test box can be used as a thermal shock test box can also be used as a separate high temperature box or a separate cold box;

Three boxes:

1. The sample is rapidly placed in a pre-cooled low-temperature room or a pre-heated high-temperature room, so the temperature change is fast;

2, room temperature box, convenient test, easy to take samples;

3, the test box can be used as a thermal shock test box can also be used as a separate high temperature box or a separate low temperature box, three box type dynamic temperature impact test box. By contrast, the three-box cold-thermal shock test box is a two-cassette modification and technology update. The three-box dynamic temperature impact tester consists of a high-temperature chamber, a low-temperature chamber, a room temperature chamber, and a test sample basket, a refrigeration system, a heating system, and a control system that move in both chambers.
