Gate direction for the production of magnesium · =

Injection molded parts.

Hiring / "relates to the production of magnesium injection molding ·» share and it is her task to create an improved device for the production of such injection molded parts «.

The device according to the invention uses a so-called "goose neck" receptacle, in his chamber and "goose neck" magnesium in front of his: Usage is saved for the formation of injection molded parts, with Heating means are provided to keep the magnesium in both the chamber and the goose neck in the molten state and on a regulated ' To maintain temperature «.

More precisely, the invention relates to a device in which a cover unit is used and is placed onto the vessel in a sealing manner and the lid unit means for pushing out the molten Magnesium included in the formation of injected end products, which means in the intermittent application of hydrostatic: Pressure by using an inert gas and then venting the Gas exist after completion of the spraying of an end product

The invention also relates to a device in which the goose neck receptacle has a holding ring, which allows the attachment and removal of the magnesium intake " unü E ^ ektoran"
