Classification of casting molding machinery

       Casting molding machines are generally classified according to modeling methods, and are customarily divided into ordinary sand casting and special casting. Ordinary sand casting includes three types: wet sand type, dry sand type, and chemical hardened sand type casting. Special castings can be divided into two categories according to different modeling materials: one type uses natural mineral sand as the main modeling material, such as investment casting, shell casting, negative pressure casting, clay casting, solid casting, ceramics. Type casting, etc.; one type of metal is used as the main casting material, such as metal casting, centrifugal casting, continuous casting, pressure casting, low pressure casting, and the like.
