Performance
SHIELDING PERFORMANCE, CONSISTENTLY
Shielding effectiveness depends on material, geometry and seam integrity. Our precision stamping holds tight tolerances on critical shielding dimensions, and our managed plating options (tin, nickel) ensure solderability and corrosion protection for board-level applications.
Shield cans, clips, gaskets and board-level shielding parts are stamped from nickel silver, stainless, brass and tin-plated steel to provide consistent shielding performance.
ISTAMPING's 0.005 mm precision and burr-free edge control ensure consistent shielding performance for automotive EMI shield stamping and solderability for telecom, consumer electronics and automotive EMC applications.

Manufacturing Process
How We Manufacture Shields
From drawing review to delivered parts — die design, stamping, plating and inspection records all owned in-house.
Why Shielding Matters
Electromagnetic interference grows with every high-frequency device; automotive EMC regulations now demand shielding across more modules than ever. The global EMI shielding market exceeds US$9.9 billion and keeps expanding with electrification.
Shield Design & Simulation
We run FEA and tooling simulation on seam geometry, vent patterns and wall height so each shield meets its attenuation target before steel is cut.
Fine-Blank & Progressive Tooling
Precision progressive and fine-blank dies built 100% in-house form cans, clips and gaskets at ±0.005 mm with burr-free edges for reliable soldering.
High-Speed Stamping
Shields are stamped in high volume with in-process monitoring on presses up to 300 SPM, holding tight tolerances on critical shielding dimensions.
Managed Plating
Reel-to-reel tin or nickel plating ensures solderability and corrosion protection for board-level and automotive EMC applications.
Inspection & Quality Control
Camera vision and CMM verification under IATF 16949:2016 confirm dimensional accuracy, seam integrity and plating quality.

In-House Tool Room
Made in Our Own Tool Room
Every progressive die behind our stamped parts is 100% in-house stamping tooling — design, machining, assembly and T1 trial all under our roof. That is why tooling issues get solved on the shop floor in hours, not by email exchange with an outside die shop.
±0.001 mm Achieved
Combined machining accuracy down to ±0.001 mm, Ra0.05 µm surfaces and Ø0.05 mm micro end mills for tight die features.
30 In-House Machines
30 die-making machines — wire EDM, CNC and precision grinding — keep every die build and repair on our own schedule.
2–5 Weeks for Stamp Dies
Typical stamping die delivery in 2–5 weeks, with T1 trials run on our own presses before you commit to volume.
One Accountable Chain
Self-designed progressive dies, machined in-house, run at 60–300 SPM with CCD inline inspection — no outsourced-die handoff where quality falls between suppliers.
INSIDE THE PLANT
Inside Our Stamping Line
Real equipment and inspection floor from our Dongguan plant — 25–110T high-speed presses, in-house tool room, and a CMM lab running first-article inspection on every program.
Engineering Support
Design-for-Manufacturability Support
Our engineers review your shield at the quoting stage - wall height, vent pattern, seam type and plating - and recommend design-for-manufacturability changes that improve attenuation and lower tooling cost. Existing dies can be taken over and optimized for our high-speed presses.
FAQ
Questions Buyers Ask
Straight answers on materials, plating, supply format, quality and timing — send your drawing for anything specific.
What EMI/RFI shield types do you make?
We stamp shield cans, board-level shields (BLS), shielding clips, EMI gaskets and RFI shields in nickel silver, stainless, brass and tin-plated steel.
How do you ensure shielding effectiveness?
We simulate seam geometry and vent patterns with FEA before tooling, then hold ±0.005 mm on critical dimensions with burr-free edges for consistent solderability and seam integrity.
Can you manage plating for shields?
Yes. Reel-to-reel tin or nickel plating runs through our approved partner lines for solderability and corrosion protection across automotive, telecom and consumer-electronics applications.
What drawing file formats do you accept?
PDF, STEP, IGES, DWG or DXF — send whatever you have with material, annual volume and target tolerance, and your drawing goes straight to our engineering team for a DFM pass. No finished drawing yet? A photo of the part or a sketch with a few key dimensions is enough to start.
