Detailed Introduction

This mold is designed as a 16-cavity double-row symmetrical structure, with 8 cavities distributed on each side of the two mold plates, greatly improving single molding cycle output. The built-in balanced runner system can make plastic melt reach each cavity at the same speed and pressure, effectively avoiding issues like uneven filling, inconsistent dimensional accuracy and warpage of individual products. The detachable insert-type cavity structure facilitates later maintenance, replacement of vulnerable inserts and adjustment of product specifications.

The mold adopts rigorous ultra-precision processing standards: the tiny cavity contours of connectors are processed by 5-axis CNC and micro EDM technology to guarantee the precision of assembly features on small connectors; the mold base and inserts undergo vacuum heat treatment to enhance hardness and wear resistance; multi-step precision grinding and mirror polishing eliminate tiny burrs, ensuring smooth demolding of thin-wall miniature parts. Cavity surfaces can be optionally treated with nitriding or PVD coating to resist abrasion and corrosion from modified engineering plastics such as glass-filled PA.

All mold components complete CMM full inspection before assembly to control the positioning accuracy of each cavity, the fit clearance between moving parts and the parting line flatness. We can carry out personalized customization according to customers’ 2D/3D drawings or physical samples, adjusting cavity quantity, runner mode, mold steel grade and ejection structure based on daily production capacity, plastic material characteristics and expected mold service life, to meet the high-volume and high-precision production needs of miniature connectors.
