Product Overview
The Car Control Box is an automotive electronic control enclosure and complete module assembly used in door, seat, and air-conditioning systems. It houses the PCB and electronic components, provides connector and mounting interfaces, and uses potting material where the module requires sealed protection.
Core Advantages
Material Options for Structural and Welded Housings
PA6+GF30 is available for mechanically loaded housings, while PC+ABS supports a tough enclosure and ultrasonic-welding design. The selected material keeps PCB supports, connector locations, and housing joints aligned under mounting and thermal stress.
Defined PCB and Connector Positioning
Internal supports locate the PCB, connector, and cover relative to the mounting points. They keep the board seated and preserve connector alignment under vehicle vibration, installation load, and thermal change.
IP67 Protection after Potting
The completed control box is specified to reach IP67 after potting. In door, seat, or air-conditioning modules exposed to moisture, dust, or cleaning conditions, the filled enclosure isolates the PCB and electronic parts from the external environment.

Customization Capabilities
Housing and Electronic Layout
Configuration options cover housing geometry, PCB outline, connector position, mounting feet, screw bosses, cable routing, component clearance, cover joint, and potting volume.
Material, Shielding, and Sealing
PA6+GF30 or PC+ABS may be specified with vacuum-coated shielding areas, ultrasonic-welded joints, mechanical fasteners, gasket details, or potting according to the module design.
Process and Module Configuration
Production can include injection molding, vacuum coating, PCB etching, electronics integration, potting, and final module assembly. Connector orientation, potting volume, coating zones, and assembly sequence are defined for each project.
Quality Control
PCB and Assembly Inspection
PCB production uses AOI inspection before the board enters final assembly. Connector orientation, board seating, component clearance, and housing closure are checked against the required assembly record.
100% Air-Tightness Control
Every potted and sealed module receives 100% air-tightness inspection. The completed module is evaluated against the IP67 protection target, and failed units are separated before packing.
Housing and Potting Verification
First-piece and patrol checks cover housing dimensions, weld or joint areas, coating coverage, connector position, potting fill, voids at visible surfaces, and final module appearance. Batch records connect the housing, PCB, potting, and release results.
FAQ
Q1: What is the MOQ for a Car Control Box?
A1: The MOQ is 10,000 pieces. Different confirmed module versions may be combined when their production and inspection plans are compatible.
Q2: What payment term is used?
A2: The payment term is 100% prepayment.
Q3: Can the product be supplied as an enclosure without the PCB?
A3: Yes. The order may cover molded housing parts only, a coated or sealed enclosure, or a complete electronic module.
Q4: Can customer-supplied PCBs or electronic parts be assembled into the housing?
A4: Yes. Incoming requirements, connector orientation, board seating, potting clearance, and the required functional checks must be confirmed before assembly.
