Gravity casting
Gravity casting refers to the process of injecting molten metal into a mold under the action of the earth's gravity, also called casting.
The generalized gravity casting includes sand casting, metal casting, investment casting, lost foam casting, mud casting,etc. The narrow gravity casting refers specifically to metal casting.
Low-pressure casting
Low-pressure casting is a casting method in which liquid alloy is pressed into the mold cavity from bottom to top under pressure,and solidified under pressure to obtain castings.
The principle of pressure casting is to pass dry compressed air or inert gas into a sealed crucible,
with the help of the pressure acting on the molten metal surface, the molten metal flows along the riser pipe from bottom to top to fill the mold smoothly through the runner ,
The filling pressure is generally 20-60kPa. When the casting is completely solidified,
the gas pressure on the liquid surface is released, so that the non-solidified molten metal in the riser pipe and the runner flows into the crucible by its own weight,
and then the mold is opened and the casting is taken out.
measuring liquid level, sealing test, mold matching, tightening mold or mold, etc.
casting and sand casting, and it is also different from pressure casting with high pressure and high speed filling.
surface of the molten metal, low-pressure casting is filled with molten metal in the lower part of the crucible through the riser pipe, which completely avoids the possibility of molten slag entering the mold cavity.
molten metal, which is beneficial to the formation of castings with clear contours and smooth surface, and is more beneficial for the molding of large thin-walled castings.
