Electronic tensile machine Key points for attention
I. tension range, test stroke and basic configuration of electronic tensile machine. Different tension range and different force sensor will lead to different structure, which will directly affect the cost of the instrument. For general flexible packaging manufacturers, the tension range of 300 n is enough; According to the performance and requirements of the flexible packaging film to be tested, the stroke is 600-800mm; Intelligent three basic configuration: host, computer, and printer, if the microcomputer function is strong, can print directly. It can also be equipped with ordinary computer. If equipped with a computer, the manufacturer should add the corresponding control system. With the help of computers, complex data analysis can be carried out, such as data editing, local enlargement, report form adjustment, and group statistical analysis.
2. Test items. Flexible packaging requires a multi-purpose tensile machine, that is, on the basis of different fixtures, it can be used for tensile, compression, bending, tearing, shearing, 180 degree stripping and 90 degree stripping tests.
3. Test speed of electronic tensile machine. Some of them are in the range of 10 ~ 500 mm / min and some are between 0.01 ~ 500 mm / min. the former generally uses ordinary speed control system, which has low cost and rough influence on precision. The latter uses servo system, which is expensive and has high precision. For flexible packaging enterprises, it is enough to select servo system with the speed range of 1 ~ 500mm / min, which does not affect the accuracy and the price is within the reasonable range.
