The height dimension of the fall-preventing projection and the injection gate mark are identical or substantially identical.

The primary cavity part (201) is attached to the fixed platen of a moulding machine in use and incorporates an injection gate (211).

The injection fluid is injected under pressure and moves the sample substance through the core.

The injection material (218) is forced through a sprue (208) into the mold cavity (204).

The height dimension of the fall-preventing projection and the injection gate mark are identical or substantially identical.

The primary cavity part (201) is attached to the fixed platen of a moulding machine in use and incorporates an injection gate (211).

A valve stem has a reverse taper thereon used in an injection nozzle for a hot runner system.

To enable the solidified sprue to be separated from the moulded article, a bush (8) is also present in which the gate (6) likewise extends.

Daucus carota L. (Carrot and Fodder Carrot

A runner section (40) is fluidly connected to said sprue passageway (38) and said plurality of mold cavities (34, 36).

In metallic material injection molding machines, the connection between the injection nozzle and the sprue bushing has tended to leak metallic material.

The injection angle (α3) of the injection hole (611C) is set smaller than the injection angle (α1) of the injection hole (611A).

The same is true for the injection direction of injection hole (611A), injection hole (611B), and injection hole (611F).

The same is true for the injection direction for injection hole (611C), injection hole (611D), and injection hole (611G).

Sealing structure is configured to seal the coinjection molding hot runner sprue bushing to the coinjection hot runner during the relative movement.
