Features of tensile testing machine

According to the industry and functional characteristics can be divided into 1, metal tensile testing machine: metal material tensile strength is large, elongation is small, need to be equipped with metal punctuation extensometer
.

2, rubber tensile testing machine: rubber or elastomer elongation is relatively large, need to be accompanied by a large punctuation elongation device, while the fixture design to consider the characteristics of suitable for rubber, can not slip
.

O-ring fixtures and tire industry fixtures can be added
.

3, plastic tensile testing machine: plastic tensile strength is greater than rubber, elongation is large and small, and often to test three-point bending test
.

4, textile tensile testing machine: the textile industry needs to test fabric fabric peeling, puncture, tearing, single yarn stretch and other tests, fixtures and software are more special
.

5, paper tensile testing machine: paper needs to test tensile strength, ring pressure strength, vertical pressure, flat pressure, side pressure, peel strength, etc.
, more
fixtures.

6, leather tensile testing machine: leather needs to test tensile strength, tear strength, etc.
, the test items are relatively simple
.

Fourth, according to the test materials: metal material fixtures and non-metallic material fixtures; Fifth, according to the test temperature: normal temperature fixtures, high temperature fixtures, low temperature fixtures, high and low temperature fixtures; Sixth, according to the use: tensile fixtures, compression fixtures, bending fixtures, shear fixtures, peeling fixtures, tearing fixtures, sealing fixtures, anti-bending and anti-bending fixtures; Seven, according to the degree of automation: manual fixtures, pneumatic fixtures, electric fixtures, hydraulic fixtures
.
