An eye for perfection
According to our welding specialist Sebastiaan Koopmans, finishing an RF-shielded door requires special skills: “A regular household door fits into a wooden or metal frame. The ‘knives’ on our doors need to fit exactly into the copper ‘fingers’ of the door frame after welding the parts together. Therefore, they must be sharp but not too sharp to wear the copper fingers. Just like a good kitchen knife. I test the welding edges of the door knives manually but safely: when they feel smooth enough, they get my green light.”
