1 , first of all should consider the need to test the material pull range.

The difference in pull range determines the different sensors used, which determines the structure of the puller , but this has little effect on the price ( except for the gate type ) . For general flexible packaging manufacturers, a tension range of 100 Newton is sufficient. Therefore, it is also decided to use a single arm type.

The structure corresponding to a single-arm type is a portal structure, which is adapted to a relatively large pulling force, such as one ton or more. Therefore, soft packaging manufacturers basically do not need.

2 , desktop pull machine test stroke problem.

According to the nature of the goods that one's company needs to test, select a model. For example, when testing a product with a large elasticity and a long length, it is necessary to communicate with the manufacturer's technical department in advance when ordering a tensile testing machine. Take flexible packaging film as an example, it needs the performance and requirements of the test. The stroke can be 600 - 1500mm . Materials with an elongation of more than 1000% can be used with a stroke of 1000 or 1200mm .

3 , the output results.

The output results can be set: maximum force, elongation, tensile strength, elongation anyone, elongation force constant value, yield strength, modulus of elasticity, the maximum test force 8. This can be said to be the most comprehensive result of the output of the microcomputer. Some foreign manufacturers' products can generally output these 8 items. Some domestic manufacturers can output 5-6 items, and some manufacturers can only output the maximum force value, average value, and minimum value.

4 , the standard configuration problem.

The three basic types of intelligent configuration: host computer, microcomputer, and printer. If the microcomputer is powerful, it can be directly printed. In addition can also be equipped with ordinary computers. With a computer, you can perform complex data analysis, such as data editing, local magnification, adjustable report formats, and statistical analysis of grouped patterns.
