Cov khoom siv qhia tias qhov tsawg kawg yog qhov seem tuab thiab qhov yuav tsum tau muaj qhov tsawg kawg nkaus rau lub casting raws li tau teev nyob rau hauv qab rooj. Cov thooj av hnyav yuav tsum tsawg tshaj 13 hli (0.5 rau), tab sis tuaj yeem ua tau ntau dua.
Hlau Tshooj cai tsawg Daim phiaj xwm txheej tsawg tshaj
Aluminium alloys 0.89 hli (0.035 tawm hauv) 1: 100 (0.6 °)
Tooj dag thiab tooj dag 1.27 hli (0.050 ntawm) 1:80 (0.7 °)
Magnesium alloys 1.27 hli (0.050 ntawm) 1: 100 (0.6 °)
Zinc alloys 0.63 hli (0.025 ntawm) 1: 200 (0.3 °)
