Mold Structure & Design Description

The beryllium copper thread core insert is installed in the core side of preform molds, directly forming internal thread geometry. The combination of BeCu material and precision CNC machining allows efficient cooling at the thread area, reducing cycle time and improving part consistency. Thread profiles, relief angles, and fitting tolerances are manufactured strictly according to customer drawings.
