EMC Shielding Enclosure — Conductive Contact Design
Enclosure built for electromagnetic compatibility rather than for looks: conductive gasket grooves, plated or chromate contact faces, aperture sizing checked against the frequency to be attenuated, and lid grounding points on a defined pitch so shielding effectiveness is repeatable after servicing. Made by WERIX Metal from SECC / tinplate / beryllium copper spring contacts to a tolerance of ±0.1mm, finished with zinc plating + conductive coating. Typical order volume is from 10 to 10000+.

EMC Shielding Enclosure — Conductive Contact Design: manufacturing notes
This part — emc shielding enclosure — conductive contact design — 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 galvanised steel
EMC Shielding Enclosure — Conductive Contact Design is specified in SECC / tinplate / beryllium copper spring contacts. Galvanised sheet carries a zinc layer that protects sheared and lasered edges where the coating cannot reach, which is why it is the default choice for outdoor and humid-service parts. It welds cleanly if the zinc is dressed back at the joint, and it takes powder coat without a primer as long as the surface is degreased and the pre-treatment is phosphated rather than simply washed.
How the part is formed
The production route for this part is precision laser, CNC bending, conductive gasket grooves. 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: electroplating
zinc plating + conductive coating. 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 emc shielding enclosure — conductive contact design?
- The order range for this part is from 10 to 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 SECC / tinplate / beryllium copper spring contacts; 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 zinc plating + conductive coating. 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.
