Problems solved by technology

[0002] The production of traditional ship propellers cannot fully guarantee the mechanical properties of their materials. In the process of propeller calibration, secondary calibration often occurs due to unqualified mechanical properties, which not only interferes with the daily production activities of the enterprise, but also wastes costs.
