Maelezo

Mchanga wa silika wenye nguvu nyingi (p):Upeo mbaya wa uso wa castings na kasoro za mishipa kwenye ukuta wa ndani
Mchanga wa kauri wa Kaist (t):Ukuta wa ndani wa uso wa kutupwa ni laini, bila kasoro kama vile mshipa

Hitimisho

Katika Shell mold coated mchanga akitoa, kulinganisha na high nguvu silika mchanga, Kaist Ceramic foundry mchanga ina faida ya nguvu ya juu, chini ya gesi mageuzi, nzuri upenyezaji hewa, muda mrefu wa upinzani joto la juu, upanuzi chini, nk, castings ni si scraped , uso wa uso unaboreshwa kwa kiasi kikubwa, na kasoro za mishipa huboreshwa kabisa.
