Abstract
Provided is an injection molding method for obtaining an injection molded article using an injection molding machine by means of filling a mold cavity of a mold with a molten copolymer from a nozzle of the injection molding machine, wherein the minimum thickness of the mold cavity is 0.8 mm or less, the total projected area of the mold is 1 cm2 or more, and the copolymer is a copolymer containing a tetrafluoroethylene unit and a fluoroalkyl vinyl ether unit, wherein the number of functional groups is 100 or less per 106 main-chain carbon atoms of the copolymer.
Claims11
An injection molding method for obtaining an injection molded article using an injection molding machine by means of filling a mold cavity of a mold with a molten copolymer from a nozzle of the injection molding machine, wherein
- a minimum thickness of the mold cavity is 0.8 mm or less, where the minimum thickness of the mold cavity is a distance between walls of the mold cavity that will form a thinnest wall part of the injection molded article,
- a total projected area of the mold is 1 cm2 or more, and
- the copolymer is a copolymer containing a tetrafluoroethylene unit and a fluoroalkyl vinyl ether unit, wherein the number of functional groups is 100 or less per 106 main-chain carbon atoms of the copolymer and a melt flow rate of the copolymer is 20 g/10 minutes or more.
