Custom Knee Braces, Ductless Air Conditioners, Window Film, Motorcycle Exhaust Systems

How It's Made – Season 22

Measurements and moulds of a patient’s leg guide the shaping of supportive shells, hinges and padding for custom knee braces. Heat-exchange coils, fans, compressors and electronic controls are assembled into ductless air-conditioning systems; thin polymer layers are coated and bonded into window film; and bent metal tubing and mufflers become motorcycle exhaust systems.
