Abstract
A molten material supply unit includes a heating cylinder. The heating cylinder may receive and heat the material in a substantially vacuum condition. A molding apparatus may include a pressurizing and charging unit in addition to the molten material supply unit. The pressurizing and charging unit is adapted to receive the melted material from the molten material supply unit and to charge the melted material into a die under pressure.
Claims56
A molten material supply unit comprising a heating cylinder constructed and arranged for receiving and heating the material in a substantially vacuum condition.
A molding apparatus for molding a material using a die, comprising:
- a molten material supply unit having a heating cylinder that is constructed and arranged to heat and melt the material in a substantially vacuum condition;
- and
- a pressurizing and charging unit that is adapted to receive the melted material from the molten material supply unit and to discharge the melted material into the die under pressure.
A molding apparatus for molding a material using a die, comprising a molten material supply unit having a heating cylinder that is constructed and arranged to heat and melt the material in a substantially vacuum condition.
A method of melting a material, comprising:
- heating and melting the material within a heating cylinder in a substantially vacuum condition;
- and
- discharging the melted material from the heating cylinder.
A method of molding a material using a die, comprising:
- heating and melting the material within a heating cylinder in a substantially vacuum condition and further injecting the melted material into the die in a substantially vacuum condition.
An apparatus adapted to melt a material selected from the group consisting of a magnesium alloy and an aluminum alloy, comprising:
- a heating cylinder having an inlet and outlet, the inlet being adapted to receive the material to be melted;
- and
- a vacuum pump communicating with the heating cylinder and being arranged and constructed to generate a reduced pressure within the heating cylinder.
A method comprising:
- heating a material into a softened state,
- inserting the softened material through an inlet of a melting chamber, wherein the softened material forms a substantially airtight seal with the inlet,
- melting the softened material within the melting chamber,
- reducing the pressure inside the melting chamber and
- discharging the melted material from the melting chamber substantially in the absence of air.
An apparatus comprising:
- first means for heating a material into a softened state,
- second means for melting the material into substantially a liquid state, the second means comprising an inlet adapted to receive the softened material,
- third means for inserting the softened material through the inlet of the second means, whereby the softened material forms a substantially airtight seal with the inlet,
- fourth means for reducing the pressure inside the second means and
- fifth means for discharging the melted material from the second means substantially in the absence of air.
