Modular SheetMetal Plastic Rack Manufacturing for Compact Personal AI Servers

Cooling and Alignment Questions for AI Racks

How do you build a personal AI server rack that safely supports high‑power GPUs while keeping the system cool and easy to maintain? This modular frame we build for an European client, combining sheet‑metal panels and polymer inserts provides a compact housing for home AI clusters or research desktops. These racks are common in personal AI setups where you need to fit multiple GPUs, route cables neatly, and shield sensitive electronics.

The housing shows a combination of bent steel plates with punched ventilation slots, circular openings and flanges, together with injection‑moulded inserts containing ribs and bosses. Primary requirements include precise fit and alignment for boards and GPUs, effective thermal management through vents and slots, and durable materials and surfaces that are safe to handle.

Design Controls for Sheet‑Metal AI Racks

What makes this rack different is the way Mastars balances structure and ventilation. Keeping GPUs aligned while letting heat escape requires precision sheet‑metal forming and polymer moulding. Our engineers jump in early with design‑for‑manufacturability suggestions on slot patterns, hole sizes and rib spacing. We start by laser cutting and bending the steel plates; then we stamp ventilation slots and circular openings. Injection‑moulded inserts with ribs and bosses snap into the frame.

During assembly, fixtures align metal and plastic parts, and gauges and coordinate‑measuring machines verify flatness and hole positions. Every build is documented for traceability.
