Speaker & Audio Equipment Enclosure — Acoustic Steel: manufacturing notes
Every part we ship has to perform in service, not just pass inspection. Below is how this speaker & audio equipment enclosure — acoustic steel is specified and manufactured at WERIX, and which details in the drawing drive cost, lead time and yield.
Why this part is made in aluminium
Speaker & Audio Equipment Enclosure — Acoustic Steel is specified in AL5052-H32 1.0mm. Aluminium buys weight reduction and thermal conductivity, at the cost of stiffness: a section that is stiff enough in 1.5 mm steel needs either a thicker gauge or formed stiffeners in aluminium. It anodises rather than paints when a hard, non-flaking surface is wanted, and it needs dedicated tooling and fixturing because the soft surface marks easily during handling.
How the part is formed
The production route for this part is deep drawing, precision laser, CNC bending. Deep drawing forms a part from a single blank, so there is no seam to seal or finish. The material is stretched rather than folded, which means the draw ratio and the blank-holder force are the design constraints, and the finish has to be applied after forming because the surface is displaced. Bending is where most tolerance stack enters a sheet metal part. We set the bend allowance from the part’s own material and radius using the K-factor the press is running, then verify the first article on the machine rather than from the drawing, because springback moves with material batch and grain direction.
What ±0.1mm actually requires on the shop floor
The drawing calls for ±0.1mm. On a part like this that is a process decision, not an inspection decision: it fixes which machine holds the critical features, how the part is fixtured for each operation, and whether a formed feature can be checked after coating or has to be measured before it. We confirm the first article against the drawing and record the values, so the tolerance is demonstrated rather than assumed. If a dimension in your drawing is tighter than this part needs, it is usually worth relaxing it — over-toleranced features are one of the quietest cost drivers in a sheet metal quote.
Finishing: anodising
anodizing Type II + brushed. Anodising converts the aluminium surface into a hard oxide layer instead of adding a film, so it does not chip and flake the way a coating can. It is the reason aluminium parts often ship anodised rather than painted, and the layer thickness is chosen for the service — decorative, wear-resistant or hard-anodised for moving surfaces.
Frequently asked questions
- What is the minimum order quantity for speaker & audio equipment enclosure — acoustic steel?
- The order range for this part is from 100 to 50000+. Below the low end of that range the tooling and setup are spread over too few pieces to be economic, so if you are prototyping we would normally build the first units from the same process route and quote the production quantity separately.
- Can the material be changed to reduce cost or weight?
- Yes, and it is worth asking before the design is frozen. The current specification for this part is AL5052-H32 1.0mm; depending on the service environment, a different grade or a lighter gauge with formed stiffening can meet the same requirement. What we would not do is change the material without re-checking the bend radii, the welding process and the coating system, because all three move with the substrate.
- What finishing options are available for this part?
- The current finish specification is anodizing Type II + brushed. Powder coating, anodising, zinc or nickel plating, brushing and blasting are all available in-house, so the finish can be changed without changing supplier — and where the part will be seen, we match colour to the RAL or Pantone reference on your drawing.
- How long does production take, and what do you need from us to quote?
- Prototypes are typically 3–7 business days and production runs 7–15 days once the drawing is released and the finish is confirmed. To quote we need the drawing or CAD file (STEP, DXF, DWG, IGES or PDF), the material and finish, the quantity and the destination — and any tolerance or inspection requirement that is not already on the drawing. You get a DFM review with the quotation, not after it.
