Heat Needs an Escape Route

Industrial mini PCs run continuously inside cabinets and factory floors, where trapped heat forces processors to throttle or crash. An aluminum alloy chassis conducts heat directly, working with fanless passive cooling to spread it across the whole enclosure; plastic traps heat inside, weakening stability under sustained load. For embedded devices operating 24/7, a heat path is not a bonus, it is a prerequisite.

Interference Needs a Wall

Motors, inverters, and high frequency equipment crowd factory floors, and electromagnetic interference can enter the motherboard through the case, causing RS232 communication errors and LAN packet loss. A metal shell forms a continuous shield that suppresses EMI; plastic offers almost none. Where strong electromagnetic fields exist, this shielding gap shows up directly in data transmission reliability.

Choose the Material by Scenario

Lightweight, low cost plastic chassis mini pc suits desktop office, while industrial hosts for production lines, security, and edge gateways rely on aluminum chassis for both cooling and shielding. Shenzhen Helor Cloud Computer Co.,Ltd. refer to these two indicators for the selection of chassis materials, and supports providing comprehensive OEM/ODM customization services.
