Every industry brings constraints that arrive before the drawing does: a standard the cabinet has to fit, an environment it has to survive, a service technician who has to open it in the rain. This cluster collects the application-specific designs on one side, and the commercial side of buying them on the other.
What this cluster covers
The application articles each start from the constraint that industry actually imposes — the ingress and impact duty on an EV charger, the fire and venting requirements on a battery cabinet, the layout and access rules on a control panel, the display and sealing detail on an HMI, the thermal and mounting reality of a telecom cabinet, and the dimensional discipline of a 19-inch rack. The sourcing articles cover what a custom enclosure costs and why, what a manufacturer actually does with your files, what drives lead time and which levers shorten it, the RFQ items that turn an enquiry into a firm quote, prototype-to-production, and the export packaging that decides whether a good part arrives in one piece.
Where to start
- If you know your industry, start with that application article, then come back to the sourcing group when you are ready to ask for a quote.
- Comparing suppliers: the RFQ checklist and the cost guide are the two articles that make two quotes actually comparable.
- If the schedule is the binding constraint: read the lead time guide first, then prototype-to-production, and check whether tooling changes the maths at your volume.
- If parts are arriving damaged: the export packaging article is the shortest path from a complaint to a fix.
