Tightening machine purchase guide

1. The need to test the tension range of the material should be considered first.
The different tension range determines the different sensors used, which also determines the structure of the tension machine, but this item has little impact on the price (except for the gantry). For general flexible packaging manufacturers, the tension range of 1,000 kg is enough. Therefore, it is also decided to use a single-arm type. The corresponding structure to the single-arm type is a gate-type structure, which adapts to relatively large tension, such as one ton or more. Therefore, flexible packaging manufacturers are basically not available.
2. Problems about the test itinerary.
According to the performance and requirements of the flexible packaging film, the stroke is 600-900mm. If the material elongation exceeds 1000%, the stroke can be 1000 or 1200mm.
3. Standard configuration issues.
Three basic configurations of intelligence: host, microcomputer, and printer. If the microcomputer has strong functions, you can print directly. In addition, it can also be equipped with a normal computer. With a computer, complex data analysis can be carried out, such as data editing, local amplification, and the report format can be adjusted, and statistical analysis of group styles can be carried out.
4. Output result.
The output results of the test results can be set arbitrarily: force value, elongation, tensile strength, constant elongation, fixed elongation value, yield strength, elastic modulus, and test force. This can be said to be a comprehensive result of the output when the microcomputer is operated.
5. On the experimental projects that can be done.
Flexible packaging requires that one tension machine is used for multiple purposes, that is, on the basis of equipped with different fixtures, tensile, compression, bending, tearing, shear, 180-degree peeling, and 90-degree peeling tests can be performed. In addition to the above items, some tensile machines on the market can also test the friction coefficient because of their high sensor accuracy (some reach one in 200,000).
The above is the purchaseTension machineIssues that should be considered and paid attention to at the time, and I hope they will be helpful to everyone.
