Product Description

This large‑diameter ventilated aluminum housing is a one‑piece precision CNC‑machined cooling component, mainly applied for motor casings, drive assemblies, high‑heat automation machinery and thermal management systems.

Many large hollow aluminum cooling parts suffer from inconsistent wall thickness, offset mounting holes, rough‑edged ventilation slots and poor cooling efficiency. Our multi‑axis CNC machining process effectively solves these common points. All ventilation grooves, bolt holes and inner cavity structures are processed under strict tolerance control.

Circularly‑distributed long ventilated slots greatly expand air contact area. Excellent thermal conductivity of aluminum accelerates heat exchange, lowers the internal working temperature and extends the service life of motors and built‑in electronic parts.

Packing

Every CNC‑machined part is carefully protected before shipment.

We wrap each workpiece with anti‑scratch protective film, then place it into shock‑resistant foam padding to avoid surface scratches, collision damage and dust contamination during transit.

All items are packed in sturdy corrugated cardboard boxes. Custom‑made inner foam is available for complex‑shaped precision components. A packing list with product specifications will be included inside the package for your inspection.

Frequently Asked Questions
Q1: Can you modify the ventilation slot size and hole distribution on this aluminum housing?
A1: Yes, this product is fully custom‑made. We can adjust outer diameter, cavity depth, cooling‑slot layout and mounting‑hole positions according to your drawings.
Q2: What surface finishes are recommended for motor heat‑sink parts?
A2: Natural as‑machined finish offers the best heat dissipation. Clear anodizing is available for extra corrosion protection.
Q3: Are you able to produce large‑diameter aluminum housings beyond the sample size?
A3: We support custom‑machining of large‑size hollow aluminum parts, please provide your dimension requirements for evaluation.
