Abstract:
A method for manufacturing a composite preform is provided, including preparing a preform that is formed from a plastic material, preparing a tubular heat shrinkable plastic member that is longer than the preform and has a margin for thermocompression bonding at one end, inserting the preform into the plastic member having the plastic member undergo thermal shrinkage by heating the preform and the plastic member, and bonding the margin of the plastic member by thermocompression.
