- Advantages of casting:
Casting method can produce products from different materials: ferrous metal (cast iron, steel, .. metal eye: aluminum, bronze, non-metallic casting: cast the statue from gypsum, xi bamboo shoots)
Castings can range from several grams to several tons such as hammers, machine platforms.
Molds have complex shapes and shapes such as machine tool body, engine cover, etc., which other methods are difficult to process or can not be fabricated.
It is possible to cast different layers of metal in a cast
The cost of making cheap castings is low due to the low investment capital and the high production capacity. Ability to mechanize and automate.
Castings are also used in the manufacture of artistic products, decoration: foot pillars, church bells, monument molding.
- Disadvantage casting flow pattern
Accuracy of shape and size is not high
Metal for pouring, peanut, bean
The metal is made of thicker castings than forged or welded.
Easy to cause defects such as deficiencies, porosity, suck, sacred, sand fire
Hard working conditions. Molded in sand molds are often not very productive.
