Intengo yensimbi yengulube iphinde yakhuphuka, futhi isikhathi esiphezulu sokuthunyelwa kwemboni ye-cast iron sifike ngaphambi kwesikhathi.
Eminyakeni yamuva nje, isidingo se-pig iron siye sanda. Ngenxa yenzuzo enkulu yemikhiqizo yensimbi. I-China iyizwe elikhulu elikhiqizayo. Ukwanda okusheshayo kwesidingo sensimbi yengulube yensimbi ensimbi embonini ye-Foundry kubangele ukushoda kwezinsiza ze-cast iron kanye ne-ductile iron kanye namanani akhuphukayo. Izinsiza zensimbi zomhlaba ziyindlala, futhi izigayo zensimbi zilahla insimbi Isidingo esinamandla nokunikezwa okunganele. Ukwenyuka kwentengo yezinto ezingavuthiwe kanye nokwenyuka kwempahla kugqugquzele ukwenyuka kwentengo yezinto ezilahliwe ezivela kwamanye amazwe, okugcine kuholele ekufikeni kusenesikhathi kwenani eliphakeme lemboni yensimbi.
