Guide you how to select a suitable tensile testing machine
For those new customers who have diffiluclty in selecting a suitable tensile testing machine, this article might help you a little.
First, to check the max. testing force of your testing material.
The material you want to test is metal materials or non-metal materials. By calculation, you can figure out it’s tensile force by the specimen’s section area and it’s tensile strength.
If non-metal materials, the testing force would be usually small. For example, like rubber, マックス. testing force is within 20kN.
If metal materials, the testing force would be usually larger. For example, like 32mm rebar, マックス. testing force would be 500kN.
For load range 1kN-300kN, the electromechanical type UTM (WDW Series) is recommended.
For load range 300kN- 2000ティッカー, the hydraulic servo type UTM (WAW Series) is recommended.
WDW-5 (5ティッカー) WDW-10/20/50/100 (10kN 20kN 50kN 100kN) WAW-300E/600E/1000E/2000E
Second, choose suitable grip system.
For various kind of material, it has different shape of specimen, so the grip is also different. A suitable testing grip will improve your testing effiency, to avoid hurt to the specimen, loosen during tensile test, etc problem. The grips system like wedge tensile grip, pneumatic grip, hydraulic operated tensile grip, rotating grip, 等.
Various kind of Grips for UTM (引張, 圧縮, Shear, 等。)
Third, confirm which testing standard or testing results do you want to get from the test.
To check which testing standard do you follow to test. For example, for metal materials room temperature tensile test, it usually conform to ISO6892.
Or what testing result do you want to get. The testing result, like max. テスト力, tensile strength, yield strength, elongation rate, modulus of elasticity, 等.
