As devices pack antennas next to radios and fast digital boards, engineers fight crosstalk, spurious emissions and failed EMC tests — late in the project when changes are expensive.
Die-cut conductive foam gaskets, shielding foils and I/O gasket assemblies engineered to your enclosure and seam geometry — with contact resistance and compression data to support your EMC design review.
Not sure which grade fits? Send us your application — our engineer replies with a selection proposal within 24 hours.
Die-cut EMI/EMC gaskets and shielding materials — electrically conductive foam, conductive fabric, copper/aluminum foil laminates — for enclosure sealing and board-level shielding.
EMI gaskets are as much about mechanics as about conductivity: too stiff and the enclosure warps, too soft and the seam leaks. ROTADIE engineers the gasket cross-section against your screw pattern and seam gaps, then die-cuts with conductive paths uninterrupted — corners, via holes and fold-over flaps included.
| Material types | Conductive foam, conductive cloth, Cu/Al foil |

| Contact resistance | <0.05 Ω/in typical |
| Compression force | Low / standard grades |
| Thickness range | 0.1 – 5.0 mm |
| Temperature range | -40°C to +120°C (gasket grades) |

| MOQ | 1 prototype run |
Specification values are typical reference values. Final values are subject to the grade datasheet and test report.
① Define the application — describe the device, the function of the part and the environment it works in.
② Send the drawing — DXF / PDF / STEP, or a dimensioned sketch with tolerances marked.
③ Confirm quantities — prototype quantity and estimated annual volume.
④ Review the proposal — we reply with material options, unit price and tooling cost within 24 hours.
⑤ Sample & validate — typical parts sampled in 3–5 working days (quoted per drawing), then mass production after your approval.
Custom die-cut double-sided adhesive gaskets and pads — 3M, Nitto, tesa and equivalent tapes converted to your exact drawing with tight tolerance, from prototype to mass production.
Custom die-cut foam gaskets and cushions from PORON urethane, EVA, EPDM and silicone foam — dust sealing, water sealing, drop protection and compression set control.
Precision die-cut electrical insulation films and fire barriers — PI (Kapton-class), PET, aramid paper and composite barrier materials for batteries, PCBs and power modules.
A board-level and enclosure-level design guide for EMI gaskets: how seam geometry, compression force and contact resistance determine whether your EMC test passes.
