A vented steel cover with louver slots, drawn then louvered. Louvers are pressed as formed flaps, not just cut slots – the flap angle deflects drips and directs airflow while the shell stays rigid. Cover and louvers are one piece, so nothing rattles loose.
Function and Design
What makes a vented cover hard is repeatability – the hundredth piece has to match the first one. Tolerances that matter are confirmed with capability data before the vented cover is quoted.
Key Features
- Vents are pierced with hard tooling after forming – clean edges, exact placement, no rework.
- Louvers are formed as angled flaps, not cut slots – drips deflect and airflow stays directed.
- Slots are pierced with hard tooling – clean edges at exact positions, batch after batch.
- Material: For the vented cover we default to carbon steel (SPCC / DC01 or to print); the grade is locked before tooling starts.
- Process: draw-and-anneal cycle sized to the vented cover depth, blank size logged per run, burr-free piercing on the second operation.
- Finish: The vented cover ships natural unless the print calls for plating or coating.
- Size: Size per customer drawing.
- Custom: OEM/ODM to drawing; free samples of the vented cover and a manufacturability review before tooling.
Applications
In service you will find this part in electrical enclosures and junction boxes, appliance and HVAC assemblies, automotive sensor and motor housings.
Why Source It From Aunov
Quality on drawn parts is invisible until it fails – a tear in the third batch, a rim that cuts a seal. Batch records are filed against your part number and kept for repeat orders.
