Featured Case Study

Electronics aluminum enclosure EMI shielded CNC machined

EMI-Shielded Enclosure for Industrial IoT Gateway

Challenge

Customer needed an aluminum enclosure for an industrial IoT gateway with EMI shielding effectiveness of 60dB at 1GHz, IP65 rating, and a premium brushed anodized finish for visible installation locations.

Solution

BestField CNC machined from Aluminum 6061 with integrated EMI gasket grooves. Lid interface was machined to 0.05mm flatness for consistent gasket compression. Clear anodize with brushed finish applied uniformly.

Result

EMI shielding: 65dB at 1GHz (exceeded 60dB spec)
IP65 water ingress test passed
Uniform brushed anodize finish with no visible tool marks
Thermal performance: 15°C lower than previous plastic enclosure
