Plastic Housing for Automotive Electronic Connectors

Designed as a signal transmission interface for automotive electronics and industrial control systems, this black rectangular housing serves as the external protective shell and positioning skeleton for connectors. It achieves rigid connection to the main equipment through multiple metal insert holes distributed around the perimeter. Its core function is to provide a stable mounting reference for internal precision electronic components, while utilizing specific cavity contours to position and protect wire harness interfaces, ensuring signal transmission stability in vibrating environments.

The part is manufactured via one-shot injection molding of engineering plastics. Key processing focuses include controlling the straightness of long cantilever structures and the relative positional tolerance of mounting hole patterns on both sides to prevent assembly interference caused by uneven material shrinkage. For the multi-pin socket area at the ends, strict control over inner wall dimensional tolerances and surface finish is required to ensure tight fitment of metal terminals and electrical insulation performance. The surrounding insert holes demand high-precision positioning mechanisms in the mold to ensure concentricity during threaded connections.

Supported by ISO 9001 and IATF 16949 quality management systems, our factory offers full-process services from mold structure design and precision injection molding to subsequent assembly. For non-standard connector housings involving multiple inserts or complex snap-fit structures, we utilize Hexagon CMMs (Coordinate Measuring Machines) during production to verify key hole spacing and contours, effectively avoiding visual defects such as sink marks and flash. Quotations and lead times are evaluated based on specific plastic material grades (e.g., PA66, PBT), flame retardancy requirements, mold cavity count, and order volume.
