A core pin is a precision mold component used to create holes, internal features, and detailed structures in injection molded parts. It is widely applied in molds requiring high dimensional accuracy, fine features, and stable production performance.

Due to its small diameter, high aspect ratio, and strict tolerance requirements, core pins require advanced machining capabilities and precise quality control to ensure proper mold assembly and consistent molding results.
