Customer Case:

A European industrial automation company required a high-reliability EMI shielding enclosure for a PLC-based control system used in a high-noise factory environment. The previous supplier faced issues with inconsistent shielding performance and weld seam leakage.

Our engineering team redesigned the enclosure using aluminum 5052 with TIG-welded continuous seams and electroless nickel conductive coating. CNC tube bending was used to create a rigid internal frame ensuring mechanical stability and grounding continuity.

After implementation, the customer confirmed improved EMI suppression performance and stable operation under high electromagnetic interference environments. The solution was later adopted into their standard product line for multiple OEM clients.
