Semiconductor Equipment Housing: manufacturing notes
This part — semiconductor equipment housing — is manufactured in our Dongguan plant. The notes below explain the manufacturing decisions behind the specification: why this material, why this forming sequence, and what the tolerance actually requires in production.
Why this part is made in stainless steel
Semiconductor Equipment Housing is specified in AL6061-T6 2.0mm / SUS304 1.5mm. Stainless is specified for corrosion resistance and for appearance in one move: the surface is the corrosion protection, so a scratch is a maintenance question rather than a rust path. It work-hardens as it is formed, which raises the bend force and pushes springback up, so bend radii on stainless are kept larger than on mild steel and the tooling is set for the higher force.
How the part is formed
The production route for this part is Precision Laser Cutting, CNC Machining, Cleanroom Assembly. Fiber laser cutting separates the blank without hard tooling, which is what makes a first article economical: the profile can change between the prototype and the production run without a die sunk. The trade-off is a small heat-affected edge, so on parts that will be painted we deburr and, where the edge is a sealing face, dress it flat before coating. Assembly is done in the same plant that forms the parts, so fit problems surface before the parts ship rather than at the customer’s dock. Because one purchase order covers fabrication and assembly, dimensional responsibility for the finished unit sits in one place.
What ± 0.02 mm actually requires on the shop floor
The drawing calls for ± 0.02 mm. 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
Electropolishing + anodizing, cleanroom grade. 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 semiconductor equipment housing?
- The order range for this part is From 1 to 200+ volume. 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 AL6061-T6 2.0mm / SUS304 1.5mm; 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 Electropolishing + anodizing, cleanroom grade. 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.
