Product Overview
The Board-to-Board Connector Mold is engineered for precision injection molding of high-density interconnect (HDI) connector housings. Designed for compact, multi-pin electronic assemblies, this plastic injection tooling ensures micrometric dimensional control for fine-pitch structures, flawless cavity alignment, and consistent multi-cavity production in high-volume manufacturing environments.
Key Advantages
Sub-Micron Cavity Control: Advanced CNC and EDM machining guarantee cavity positioning tolerances within ±0.005 mm.
Balanced Melt Delivery: Optimized hot and cold runner systems ensure uniform cavity filling, preventing short shots in thin-wall zones.
High-Rigidity Mold Base: Reinforced mold frame architecture minimizes deflection under extreme clamping and high injection pressures.
Excellent Thermal Management: Engineered cooling channels maintain uniform mold surface temperatures, reducing dimensional drift during prolonged production.
Superior Wear Resistance: Premium component steel resists abrasion from high-temperature, glass-filled engineering plastics.
