I. Core components and functions

1. ‌Mold Components

   Includes modules such as shell (determines connector shape), mandrel (forms inner cavity structure), slide (enables molding of complex functional parts), and cooling system (controls production temperature).
   For example, mold mandrels are made of high-strength materials such as tungsten steel to ensure the accuracy of the connector's internal cavity.

2. Adaptable Connector Type

   It is mainly used for the production of high-speed connectors (e.g. Fakra, Mini Fakra, HSD, etc.), which support the signal transmission of sensor data, in-vehicle networks (e.g. Ethernet) and intelligent driving systems (ADAS).

3. ‌Performance Requirements‌

   High frequency transmission‌: Need to meet the high-speed data flow of in-vehicle cameras, radar and other equipment, to replace the traditional Fakra Mini Fakra has become mainstream due to its small size and high degree of integration.

   ‌stability‌: The mold design needs to ensure that the connectors maintain contact reliability in environments such as vibration and temperature changes.

II. Technical barriers and production challenges

1. ‌Precision manufacturing‌

   Molds need to achieve micron-level accuracy, such as sliders that require complex trajectories to form watertight sealing structures or locking mechanisms.

2. ‌Materials and Processes‌

   Mould materials need to be resistant to high temperature and wear (e.g. alloy steel), and need to be optimized with the injection molding process cooling channel design to avoid deformation of the connector parts.

3. ‌Verification cycle‌

   It needs to pass the strict certification of OEMs (e.g. IATF16949), and it usually takes 1-2 years from mold development to mass production, which involves electrical performance and durability testing of connectors.

III. Industry trends

1. ‌Accelerated domestic substitution‌

   Domestic manufacturers break through the mold core technology through high R&D investment, and gradually replace overseas suppliers, especially in the field of Mini Fakra and HSD connectors.

2. ‌Integration and Miniaturization‌

   Tooling design tends to be more compact, for example, through multiple slider synergies to achieve high-density pinouts for connectors, adapting to the space constraints of in-vehicle electronics.
