Abstract

Vessels used for melting material to be injection molded to form a part are described. One vessel has a body formed from a plurality of elongate segments configured to be electrically isolated from each other and with a melting portion for melting meltable material therein. Material can be provided between adjacent segments. An induction coil can be used to melt the material in the body. Other vessels have a body with an embedded induction coil therein. The embedded coil can be configured to surround the melting portion, or can be positioned below and/or adjacent the melting portion, so that meltable material is melted. The vessels can be used to melt amorphous alloys, for example.

Dependent claims

A vessel for melting meltable material comprising:

a body extending longitudinally in a horizontal direction with a melting portion configured to receive meltable material to be melted therein, the body comprising:
a plurality of elongate segments arranged to form a melting surface;
an insulating material between each of the plurality of elongate segments to electrically isolate each segment from an adjacent segment;
the insulating material spaced a distance from the melting surface to form indentations in the melting surface;
and
the body including a first opening to receive a plunger for horizontally moving the meltable material from the melting portion through a second opening;
wherein the body comprises a substantially U-shaped structure.
