High-quality semi-solid slurry manufacturing apparatus and method using optimized process parameters, and component molding apparatus including semi-solid slurry manufacturing apparatus

A semi-solid slurry manufacturing apparatus using a slurry cup, the apparatus comprising:

• a high-pressure washing unit configured to simultaneously remove and cool a foreign substance in the slurry cup by using high-pressure air blow;
• a release agent coating unit configured to apply a release agent to an inside of the slurry cup in which the foreign substance is removed and cooled by the high-pressure washing unit;
• a preheating unit configured to preheat the slurry cup to which the release agent is applied by the release agent coating unit;
• an injection unit configured to inject a molten metal into the slurry cup preheated by the preheating unit;
• and
• an electronic stirring unit configured to electronically stir the slurry cup into which the molten metal is injected by the injection unit.

A semi-solid slurry manufacturing method comprising:

• ladling a molten metal in a melting furnace;
• injecting the ladled molten metal into a slurry cup;
• electronically stirring the molten metal injected into the slurry cup;
• and
• separating the stirred molten metal from the slurry cup,
• wherein the electronic stirring starts before or during the injection of the molten metal to electronically stir the injected molten metal and is performed for 10 seconds to 30 seconds after the injection of the molten metal is completed.
