Automotive Seat Frame/Bracket: manufacturing notes
Every part we ship has to perform in service, not just pass inspection. Below is how this automotive seat frame/bracket is specified and manufactured at WERIX, and which details in the drawing drive cost, lead time and yield.
How the part is formed
The production route for this part is Progressive Die Stamping, Robotic MIG Welding. Stamping moves the cost from the labour line to a hardened die, which pays off from a few thousand pieces upward: cycle time stops being a labour cost and becomes machine time, and every subsequent part inherits the die’s tolerances instead of the operator’s. Below that volume the same geometry is normally lasered and formed. MIG welds at a higher deposition rate than TIG, so it suits heavier gauges and long runs of structural joints. The trade-off is a slightly wider heat-affected zone and a weld bead that usually wants dressing where it shows, both of which are built into the process sequence when we quote.
What ± 0.1 mm actually requires on the shop floor
The drawing calls for ± 0.1 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.
Frequently asked questions
- What is the minimum order quantity for automotive seat frame/bracket?
- The order range for this part is Tooling + run from 10,000 pcs. 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 — material substitution is one of the first things we raise in a DFM review, because it affects bend radii, welding process and coating system at the same time. Send the drawing and the service environment and we will set out the options.
- What finishing options are available for this part?
- The current finish specification is E-coat primer, cathodic electrodeposition. Because every finishing line runs in-house, the finish can be changed without changing supplier, and we match colour to a RAL or Pantone reference on the 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.
