types of casting of aluminum alloys

There are many types of casting of aluminum alloys, according to the customary modelling method is divided into: ① ordinary sand casting, including wet sand, dry sand and chemically hardened sand type 3 categories. ② special casting, according to the modeling materials can be divided into natural mineral sand and stone as the main modeling materials for special casting (such as fusion casting, clay casting, foundry shell casting, negative pressure casting, solid casting, ceramic casting, etc.) and metal as the main casting materials for special casting (such as metal casting, pressure casting, continuous casting, low-pressure casting, centrifugal casting, etc.) two categories.

Casting process usually includes: ① casting (so that the liquid metal becomes a solid casting container) preparation, casting according to the materials used can be divided into sand, metal, ceramic, clay, graphite type, etc., according to the number of uses can be divided into one-time type, semi-permanent type and permanent type, casting preparation is the main factor affecting the quality of the casting; ② casting metal melting and pouring, casting metal (casting alloys) are mainly cast iron, cast steel and casting non-ferrous alloys; ② casting metal melting and pouring, casting metal (casting alloys) cast steel and casting non-ferrous alloys; ③ casting processing and inspection, casting processing, including the removal of the core and casting surface foreign matter, removal of pouring mouth, shovel grinding burrs and phi seams and other protrusions as well as heat treatment, shaping, rust treatment and rough machining.
