The yarn passing plate structure of the injection mold is not reasonably designed, which cannot ensure that the yarn is fully separated and impregnated with resin. The large inner cavity of the glue injection section will cause excessive waste of resin and increase the cost. The glue injection section and the glue extrusion section are not provided with a reasonable transition zone, and the yarn is easy to be abraded. The structure design of the glue extrusion section is not scientific, which cannot make the resin in the cavity fully flow and the yarn further impregnate to ensure complete impregnation. The glue extrusion section and the curing section are provided with an extension section to control the heat transfer, which is not reasonable. The extension section is metal and has good heat conductivity, which cannot well reduce the heat transfer from the curing mold to the glue extrusion section and the glue injection section, which will cause the resin in the glue extrusion section and the glue injection section to gel prematurely, shorten the service life and reduce the performance of the prepared product. The production line does not monitor the yarn breakage, which can cause the broken yarn to be not found in time and reduce the product performance. The electronic temperature control device often has deviation between the displayed temperature and the actual temperature, which is not convenient for the real control of the glue injection section temperature.
