How to Make Strong Engine Cylinder Head From Hot Molten Iron. Korean Metal Casting Molding Factory

Engine parts manufacturing plant located in Ansan, Korea This company develops and mass-produces industrial and defense engines and marine generator engines. What this factory makes today is an industrial ‘engine cylinder head’. Molding sand mold production line This is a cylinder head mold made of Chemiwood material.

combining wooden frames This is molding sand (sand) used to make molds. It is used by mixing additives into sand. It can withstand the pressure and high temperature of molten metal and is also resistant to shock.

Pour the molding sand into the wooden mold. Press the sand firmly and fill it without any gaps. Remove any remaining sand and level it.

Create a hole for the molten iron to enter. Gas outlet and molten iron inlet Separate wooden frame Remove the mold by gently tapping it with a hammer. Casting core manufacturing line molding sand mixer Put the mixed sand into the machine.

casting core mold sand blowing Sand is poured into the mold under high pressure. Fill with sand to leave no gaps. It releases gas.

wooden mold separation I was worried that the core might be damaged when he hit it with a hammer. completed casting core casting core moldwash Dip the core into a liquid containing dissolved iron oxide. Heat to remove alcohol and dry quickly.

Apply the liquid to the sand mold as well. Assemble the core and sand mold. completed formwork scrap metal melting operations Molten iron made by melting scrap metal over a long period of time It is a high-temperature molten iron exceeding 1500 degrees.

melt-added alloy dissolving additives When they poured the molten iron, it was so hot that I thought the camera would melt. impurity remover Removes impurities inside molten iron. injection operation Pour hot molten iron into the mold.

There was a stinging smell when it combined molding sand and molten iron. Cool for at least 10 hours after injection. Molten iron hardens after cooling Demolding Shot blast Remove foreign substances stuck to the surface.

I wanted to take a picture of what was inside, but I held back because I thought I would also be removed. By-product removal grinding Grinds sharp surfaces smooth. CNC precision cutting machining line Front cutting The cutting operation takes place inside the machine.

side cutting valve guide assembly Remove the cutting oil with an air gun. border polishing precision inspection measurements State-of-the-art measuring equipment accurately measures structure, length, and size. Appearance inspection process The exterior is carefully inspected by shining a light on it.
