A direct injection molding apparatus and a method of injection molding

A method of injection molding, the method using an apparatus comprising

• a mold cavity member having a mold cavity,
• a melt channel,
• an injection chamber,
• an injection gate having an injection gate hole controllable by a movable filling valve
• a movable injection sleeve and
• at least one injection channel,
• said method comprising the steps of
• providing a flow of molten material from a source of molten material to the injection chamber via the melt channel, the purged melt moving the movable injection sleeve to create a desired injection volume in the injection chamber while the at least one injection channel is closed by said movable filling valve,
• closing the flow of molten material from the source of molten material when an amount of molten material received in the injection chamber corresponds to the mold cavity,
• opening the injection gate hole,
• transferring the amount of molten material in the injection chamber through the at least one injection channel to the mold cavity via movement of said movable injection sleeve,
• closing the movable filling valve and
• resuming the flow of molten material from the source of molten material to the injection chamber via the melt channel.
