A, first of all should make sure that your products are need to do what test
, because also known as universal testing machine, tensile testing machine to test various materials, semi-finished products and finished products of tensile, compressive strength and elongation, elongation, can do the peel, tear, bending, bending, compression, etc.
Various types of tensile testing machine, the matched jig is different, the price, of course, also the same.
Second, the need to consider tension range, for general flexible packaging manufacturers, tension range around 200 n is enough, namely single arm, the other is large gantry, 1 ton, like do steel manufacturers will consider to use, or more.
Three, stroke, according to their own products, generally the tensile testing machine available in the market of trip is in commonly 600 - mm
1000 mm between, to test the product should be suitable for most of the manufacturers, parts materials.
Four, measurement speed at a rate of 200 mm/min of national standard, there are 10 to 500 mm/min between equipment market, there are zero.
001 ~ 500 mm/min and higher precision, the former general use ordinary motor, CVT, the precision is low, the price is relatively cheap;
The latter is used servo motor, computer servo system, high precision, high resolution;
According to the required for each manufacturer to choose.
Five, including force measurement precision, speed, accuracy and precision of deformation, displacement accuracy.
These values the highest precision can be reached plus or minus 0.
5, for the average amplitude 1% accuracy is enough, in addition, the basic value resolution can reach more than one over one hundred thousand of that sort out small make up tension tester purchase considerations, the more questions you are welcome to inquire.
