  1. Innovative Structural Design for Enhanced Load - Bearing
    The metal overmolding dies for automotive gantry frames adopt split - slider structures and sequential valve control technology. This ensures a tight bond between the aluminum alloy skeleton and high - strength nylon (PA66 + GF30) overmolding layers, significantly boosting torsional resistance. It withstands complex vibrations in the engine compartment and securely supports critical components like radiators and water tanks.
  2. High - Temperature - Resistant Materials and Efficient Molding
    The die body is made of pre - hardened NAK80 steel, polished to reduce plastic flow resistance. For the gantry frame's high - temperature environment, modified PPO overmolding materials (resistant to >150℃) are used. Conformal cooling channels optimize die surface temperature, enhancing molding efficiency.
  3. Full - Lifecycle Quality Control
    Moldflow analysis optimizes gate placement to avoid weld lines weakening structural strength. During production, laser displacement sensors monitor metal skeleton positioning, while coordinate measuring machines conduct full inspections on critical mounting holes of the gantry frame.
