Imithetho yezifundo zezifundo zomhlaba (core):

inkanyezi: izinyawo ezihambisana azikwazi ukudunyiswa okuhle, kodwa ukukhohlwa kwesipho sokunikeza kuyokwenza ukuphuma kwesandla, ukukhoma; kuya kwi isiZulu

2, refractory: imetalu yemithi enomlilo ngeke iyoleke ngaphandle, uma ikhona imithi enomlilo, ethambile ekuseni kwezindlu yomoya, ekwenza ukukhetha, ukukhetha okukhulu, ukukhetha okukhulu;

Kwesinye isikhathi, izidingo zetekhnoloji zomhlaba:

ukusiza, ukunyakaza, ubukhulu, ububanzi bukhona kwezinyanga zokugcina;

2, isitayela esifushane, isitayela, isitayela, isitayela esifushane ungakwazi;

3, ukwenziwa ngamunye, ukwenziwa ngamakhine kungaba;

4, izimpawu ezihlukahlukene zezinto ezibomvu, ezimile, ezithuthukiswayo!

　　Manufacturers do not require high series of automatic horizontal molding machine sand type, dry sand type and wet sand, good initial viscosity, viscosity in general, red sand, black sand beach, sand coal can be used.

Izinto ezinhle kakhulu zokwenza izinto zokucubungula zingasetshenziswa kakhulu kwezinto ezihlanu ezihlanu, izinto ezihlanu ezihlanu zingasetshenziswa kakhulu kwezinto ezimbalwa.
