Choosing the right aluminium enclosure for electronic equipment means answering several practical questions about cost, earthing, cooling, finishing and installation.
How can the cost of a fabricated enclosure be reduced?
Using a standard enclosure and customising it is generally quicker and more cost-effective than designing a completely bespoke housing. Simple geometry, standard features and early consultation can all help reduce manufacturing complexity and cost.
Are custom 19-inch aluminium enclosures expensive?
Not necessarily. METCASE’s COMBIMET rack cases are designed for cost-effective customisation, and the wide range of standard sizes and configurations means many projects require only limited modification.
How should a metal electronic enclosure be earthed?
For reliable earth bonding, METCASE recommends self-clinching stainless-steel fasteners and a dedicated protective earth point on the main chassis. Many METCASE enclosures include earthing studs on each panel as standard.
Is ventilation alone enough for heat dissipation?
It depends on the power level and internal layout. Natural convection can work well for lower heat loads, but the thermal requirement should be properly assessed. PCBs, cabling and sub-chassis can obstruct airflow, and higher heat loads may require fans, blowers or fan trays.
Which finish is best for aluminium enclosures?
Fine-textured powder paint is a popular choice because it is durable, resistant to scratching and provides a professional appearance. METCASE keeps a broad selection of colours in stock and can also provide custom finishes.
Can aluminium enclosures be used for display-mounted electronics?
Yes. METCASE offers desktop, rack, wall-mount and VESA-mount aluminium enclosures suitable for displays, HMIs and touchscreens, with options for brackets, threaded stand-offs and mounting plates.
