Mumakore achangopfuura, indasitiri ye graphite mold yave ichikura nekukurumidza, uye ma castings akagadzirwa ari nyore kugadzira, emhando yepamusoro, uye hapana zvasara mu casting pachayo. Kuti isangane nemaitiro ari pamusoro apa, mold ine scale graphite inofanirwa kusarudza yakakodzera kugadzirisa, nhasi Furuite graphite xiaobian ichakuudza nezvehunhu hwemold ine scale graphite:
Hunhu hwe flake graphite yeforoma (Mufananidzo 1)
Chekutanga, chiyero chekupisa chegraphite yemold flake chakakwira. Kumhanya kwekutonhora kunokurumidza uye casting inogona kubviswa nekukurumidza uchishandisa graphite molds.
Chechipiri, ine simba rakati remuchina. Kana tembiricha yekukanda yakakwira, chiumbwa chinofanira kuchengetedza chimiro chayo, kuitira kuti kukanda kugadzirwe zvakanaka.
Chechitatu, thermal expansion coefficient idiki, kupisa kwakasimba. Chimiro chemould nehukuru hwacho zvidiki kana chadziiswa uye chatonhodzwa, saka zviri nyore kuchengetedza kunyatsorongeka kwechinhu chakakandwa.
Chechina, vane mashandiro akanaka ekugadzira michina.
Five, graphite oxide zvakananga mugasi volatilization, workpiece haigoni kusiya chero zvasara.
