impact testing machine manufacturers

Ultralow-temperature Automatic Impact Testing Machine is used to test metallic materials to resist the impact to determine the nature of the material under dynamic load performance. It’s a necessary testing machine, not only used in the metallurgy, machine manufacture etc areas, but also used for the science research.

Computer controlled Ultralow-temperature Automatic Impact Testing Machine, which adopts PC computer control, this machine can auto-complete the following actions: rising pendulum, hanging pendulum, sending specimen, positioning, impacting, temperature conditioning and computer measurement and  calculation, which also can display the results and printed out with high efficiency and high accuracy. After impacting the specimen, the machine can raise pendulum with surplus energy automatically so as to be ready for the next test. Done in a continuous low-temperature impact testing laboratories and a large number of low-temperature impact tests in metallurgy, machinery manufacturing and other industries, this kind of process can reflect its better advantages. PC machine can display material impact absorption power, impact toughness, pendulum raising angle and test average value, and can print the test data and the average value of the test. JBDW-500C impact testing machine used liquid nitrogen refrigeration technology to achieve uniformity of the sample auto-cooling and temperature, temperature regulation are electrical automatic control, equipped with special guiding device automatic feeding, automatic face positioning, and ensure sample baked to impact time is not more than 4 seconds, satisfy metal low-temperature charpy impact test method request, In line with national standard GB/T3808-2002 “pendulum-type impact test machine inspection”, according to national standard GB/T229-2007 “metallic materials Charpy pendulum impact test method”, this testing machine can conduct impact tests on metallic materials, which is also in accordance with JJG145 – 82 “pendulum-type impact test machine test procedures.”
