Problems solved by technology

The current nylon composite material contains glass fiber, among which, the commonly used glass fiber cross-section is circular, and its orientation degree in the composite material is relatively high, so the parts prepared from the composite material are prone to warping, affecting product appearance
Secondly, when the parts made of nylon composite materials are used in some scenarios, such as the parts of patch magnetic cores, they have high requirements for the solder resistance of the product. If the solder resistance is poor, it will lead to The problem of expansion and cracking of parts due to thermal shock of solder
