low pressure casting mold
Relative article about how to overcome casting defects
aluminum castings are prone to defects such as internal porosity, shrinkage cavity and porosity during the casting process. After machining, the surface dense layer parts of these castings with defects are removed and the internal tissue defects are exposed.
for automobile cast aluminum parts with sealing requirements, such as cylinder block, cylinder head, intake manifold, brake valve body, etc., during the pressure-resistant sealing test, the existence of defective micropores will cause the leakage of the sealing medium and cause a large amount of waste. And these defects are often found after machining after pressure test, resulting in serious waves of working hours, raw materials and energy.
In order to solve the problem of high rejection rate of aluminum castings for automobiles and save castings that may be scrapped due to the above defects, certain treatment measures must be taken in production. At present, the common technology used in Z is infiltration treatment, that is, plugging. The so-called "infiltration" is to penetrate the infiltration agent into the micropores of the cast aluminum parts under certain conditions, and after curing, the filler in the infiltration pores is connected with the inner wall of the casting pores to block the micropores and make the parts Meet the process technology of pressure, anti-seepage and leak-proof conditions.
