How Hardware Startups Use Vibration Welding for Sealed Enclosures
In this episode of Hardware Startups with Fexingo, Lucas and Luna dive into vibration welding — a friction-based joining technique that hardware startups use to create strong, hermetic seals on plastic enclosures without adhesives or fasteners. They explore why this method is gaining traction among medical device makers and consumer electronics startups, using the example of a continuous glucose monitor enclosure that needs to survive a week in a shower. Lucas explains the physics: 100-240 Hz oscillation, 0.5-2 mm amplitude, melt depths of 0.2-0.5 mm. They contrast it with ultrasonic welding…
