Laptop & Tablet Internal Brackets — Precision
Internal brackets that position batteries, boards and hinges inside laptops and tablets: 0.3–1.0 mm steel or aluminium, hole positions held to ±0.05 mm, flatness controlled so the bracket does not preload the board, and tapped or press-fit threads for M1.6–M2.5 fasteners. Made by WERIX Metal from SUS304 0.3mm / CU110 0.2mm to a tolerance of ±0.1mm, finished with nickel plating or passivation. Typical order volume is tooling + run 10000+.

Laptop & Tablet Internal Brackets — Precision: manufacturing notes
This part — laptop & tablet internal brackets — precision — 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
Laptop & Tablet Internal Brackets — Precision is specified in SUS304 0.3mm / CU110 0.2mm. 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 progressive die stamping. 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.
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: electroplating
nickel plating or passivation. Plating puts a metallic layer on the part for corrosion protection, conductivity or appearance. Because plated finishes are thin, they follow the surface underneath: a scratch or a forming mark in the substrate shows through, so the finish is planned after the forming sequence rather than specified independently of it.
Frequently asked questions
- What is the minimum order quantity for laptop & tablet internal brackets — precision?
- The order range for this part is tooling + run 10000+. 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 SUS304 0.3mm / CU110 0.2mm; 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 nickel plating or passivation. 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.
