Glossary of Casting Terminology "E"
|Once the mold is completely filled and the casting has solidified, it is released (ejected) from the mold using its ejector pins, etc.
|The generic name for the pins incorporated into a mold for removing a casting from it via ejection. They require high abrasion resistance and toughness, and with high-pressure die casting in particular, they are made of a special tool steel variant with a hardness of 55 HRC or higher.
|What happens when breakage of the insulating material or the like results in an electric current taking a path other than through the intended electric circuit. It may cause electric shock to humans, fire, loss of power, etc.
|Something made from one type of atom and is the base component of a substance.
|The amount of deformation when a tensile force is applied to a material.
|Lettering raised or protruding from the surface of a casting.
|A device for qualitative and quantitative analysis that applies energy to a metallic sample to cause it to emit light via electric discharge. It then examines the wavelengths emitted with a spectrometer to determine the type and quantity of the elements contained in the sample.
|The numbers or letters, etc., engraved in a cast piece to identify it.
|When the surface of a casting, mold, etc., suffers etching due to a chemical reaction caused by water, a chemical agent or the like.
|A type of solidification form and crystal structure created as an alloy metal solidifies, and two or more solid phases crystallize simultaneously from the liquid metal during solidification.
|Discharged combustion gas from an engine or expelling the air from inside a mold, etc.
|A bolt with a looped head that is screwed into threaded holes in a mold or other equipment, enabling the hooks on the end of the cables of a roof crane to be attached and lift the item.
