Aluminum Housings for Rail Door Controllers

Requirement

The customer’s door controllers mount inside the passenger compartment wall and see door-cycle vibration and temperature swings. Housings must keep out dust and moisture, connector faces must allow service without removing the unit, brackets must carry weight and vibration without loosening, and with long spare-part life cycles the process must stay stable batch to batch.

Our approach

Housings are machined from solid aluminum to reduce seams. Connector panels are machined separately and assembled with a flatness-corrected seal face and groove. Brackets are thickened with ribs at bolt positions, tapped holes checked piece by piece with go/no-go gauges, and interiors deburred and cleaned so no residue affects insulation.

Delivery and inspection

First batch of 40 sets with seal-face and thread records; housings and brackets boxed separately to avoid transit damage.

Project summary

Sealing and insulation checks passed and vibration testing showed no loosening. Connectors are easy to service without dismantling the unit, and the housing now serves two door control platforms.
