Gravity casting process is the way of pouring molten aluminum into mold by hand (Traditional casting ) compare to die-casting process by machine.
This casting process is difficult to produce in large q’ty & required both advanced technology & craftsmanship.
(Even heat temperature)
(Hot spot occured)
Gravity Casting AL
No burning mark after 10min.
Die casting AL
Smoked & Burned after 5~6min.
(uniformly structured molecular base makes heat distribution faster)
(impurities (black dots) interefere heat distribution.)
