AC-DC / DC-DC Converter Housing

High-thermal-conductivity aluminum die casting for EV power conversion units. Optimized for deep cooling fin integration, tight machining tolerances, and reliable coolant sealing.

Manufacturing Challenges We Control

Delivering converter housings requires strict management of heat sinks, internal flatness, and O-ring sealing precision.

Heat Sink Integration

Converters generate intense heat. We specialize in casting deep, dense cooling fins without sink marks or cold shuts, maximizing the heat dissipation surface area.

O-Ring Groove Precision

Coolant leakage into the electronics cavity causes catastrophic failure. We maintain strict control over CNC tooling to ensure flawless surface roughness (Ra) inside sealing grooves.

Internal Coplanarity

PCBs and power modules require perfectly flat mounting pedestals for effective heat transfer. Our multi-axis CNC process ensures strict coplanarity across all internal mounting bosses.
