Application cases

Digital cantilever beam simply supported beam combined impact tester

1、 Product introduction:

 & nbsp; This instrument is a new multi-function cantilever beam and simply supported beam integrated impact testing machine. It does not need to dismantle the fixture and sample holder. The cantilever beam and simply supported beam test methods are automatically switched. It is convenient to use, simple to operate, and has high test accuracy. It is mainly used for the measurement of impact toughness of non-metallic materials such as hard thermoplastic molding and extrusion materials, hard thermosetting molding materials, and fiber reinforced thermosetting and thermoplastic composites< br />

3、 Product features:

Ø& nbsp; Integrated impact of cantilever beam and simply supported beam, without dismantling fixture and sample holder

Ø& nbsp; High precision intelligent controller, equipped with LCD, can read data intuitively and accurately

Ø& nbsp; It is the first company in China to use carbon fiber pendulum rod (which has applied for a patent) to improve the rigidity of materials in the impact direction and focus the impact mass on the center of mass of the pendulum, so as to truly achieve shock free impact test and increase the service life< br />
Ø& nbsp; Imported high resolution digital encoder is adopted, with higher and more stable angle test accuracy

Ø& nbsp; The impact hammer and imported ball bearing that conform to the aerodynamic principle greatly reduce the friction loss caused by machinery

Ø& nbsp; The final result is calculated automatically. The test data can be saved into 12 groups and averaged

Ø& nbsp; Chinese and English operation interfaces can be selected, and the test results can be in units of J/m, KJ/㎡, kg cm/cm, ft ib/in, etc.

Ø& nbsp; Built in micro printer printing test data
