Lost foam casting manufacturers supply gray iron castings and machine tool castings

  In the pouring process production of machine tool castings, the principle of high temperature discharging and low temperature pouring should be followed
Because increasing the discharge temperature of molten metal is conducive to the melting of inclusions and the floating of molten slag, which is convenient for slag removal and degassing, and reduces the slag inclusion and pore defects of machine tool castings; A lower pouring temperature is conducive to reduce the gas solubility and liquid shrinkage in the liquid metal and the baking of the cavity surface by the high-temperature liquid metal, so as to avoid defects such as pores, sand sticking and shrinkage
Therefore, on the premise of filling the mold cavity, try to use a lower pouring temperature
The process of injecting molten metal from the ladle into the mold is called pouring
Improper pouring operation will cause defects of machine tool castings such as insufficient pouring, cold shut, air hole, shrinkage cavity and slag inclusion

Lost foam casting technology is made of foam plastic, which is exactly the same as the structure and size of the parts
It is impregnated with fire-resistant adhesive coating
After drying, it is made by dry sand molding, vibrated and compacted, and then poured into the molten metal to make the mould vaporized and disappear
Lost foam casting is a new technology with nearly no allowance and accurate forming
It does not need to close the box and take the mold
It uses dry sand without binder to reduce pollution
It is considered to be a green casting technology
