Abstract

A method of molding and apparatus of the same is disclosed. A melted material is fed into an empty measuring chamber; a pre-determined amount of the melted material is transferred from the empty measuring chamber to an empty mold chamber via a transferring passageway adjacent to the empty mold chamber; the melted material in the transferring passageway is pushed to the empty mold chamber by a sealing piston until the port defined between the transferring passageway and the empty mold chamber is sealed by the sealing piston and one guiding plane of the sealing piston is served as one part of the peripheral wall of the mold for providing a method of molding an article and the apparatus for the same; when the sealing piston starts to work, less than 90 percents of the empty mold chamber is filled with the melted plastic material; and when the sealing piston starts to work, the melted plastic material is still transferred from the empty measuring chamber.
