Terminal crimping is usually the use of special terminal machine for operation, it has very strict technical standards, mainly including: pull force size, symmetry... And so on.

If the terminals are not crimped correctly on the cable, you will forget all the hard work that went into selecting the right terminals. While there are common crimping height issues that can reduce the reliability of your product, they can be easily avoided with a little knowledge and foresight.
The crimp height is the cross section height of the body crimp area after crimp, and it is the most important feature of good crimp. Terminal manufacturers have increased the crimp height for each cable size designed for the terminal. The correct crimp height range or tolerance for a given cable may be as small as 0.002 ". Under such strict specifications, it is important to verify that the crimp machine is set up correctly to obtain good crimp.
If the crimping height is too small or too large, the crimping strength (holding force against the cable terminal) cannot be provided. As a result, the drawing force and rated current of the cable are reduced, and the performance of the crimping terminal is degraded in abnormal working conditions. Too small crimping height can also crush the conductor core or just break the metal in the conductor crimping area.
