Abstract
A low-pressure balloon, and method of forming same by the steps of: preheat a thin film of thermoplastic polymeric material to a sufficient temperature; forming two halves of the balloon on said thin film of thermoplastic polymeric material by vacuum suction; isolating the two halves of the balloon from said thin film of thermoplastic polymeric material; bonding the two halves together on their edges to form the low-pressure balloon by radio-frequency welding method; and inverting the low-pressure balloon from inside out to turn the rough bonded edge of the two halves into the interior side of the balloon.
Claims18
A method for manufacturing low-pressure balloon, comprising the steps of:
- (a) providing a thin film of thermoplastic polymeric material;
- (b) heating the thermoplastic polymeric thin film to a sufficient temperature for vacuum forming thereof;
- (c) forming a first half section for a balloon on the thermoplastic polymeric thin film by vacuum suction;
- (d) forming a second half section for the balloon on a same or different thermoplastic polymeric thin film by vacuum suction;
- and
- (e) bonding the first half-section to the second half-section along edges of the half-sections to form the balloon.
