Embodiment 3
[0051] In Example 3, it can be found that the error between the conventional tensile strength value and the actual breaking strength value that is not processed by the method of the present invention is 33.5%, and the error between the calibration value obtained by using the method of the present invention and the actual breaking strength value is only 0.46% .
Embodiment 5
[0052] In Example 5, it can be found that the error between the conventional tensile strength value and the actual breaking strength value that is not processed by the method of the present invention is 26.5%, and the error between the calibration value obtained by using the method of the present invention and the actual breaking strength value is only 0.48% .
[0053] It can be seen that the existing national standard method of testing the tensile strength by injection molding into a spline cannot well reflect the failure strength that the actual part can withstand. The damage strength that can be withstood will lead to wrong estimation, which will lead to the occurrence of problems such as product misuse and vulnerability.
[0054] The equipment used in the method of the invention is simple, easy to implement and operate, reduces design and processing costs, shortens the design and development cycle of the entire product, improves the qualification rate of parts, greatly imp...
