Study Notes
Die Casting
- Offers fast production rate, long service life, and close tolerance
- Is economical and used for casting complex applications
- Offers good processing properties, high electrical conductivity, corrosion resistance, strength, hardness, and thermal conductivity
- Good EMF/RFI isolation
Disadvantages of Die Casting
- High die cost and entrapped gases in the form of porosity
- Metals with high melting points cannot be used
- Long lead time and smaller production runs may not be cost-effective
Applications of Die Casting
- Suitable for casting medium-sized parts with complex details
- Often used for nonferrous metals like magnesium and aluminum
- Used to manufacture consumer, commercial, and industrial products like automobiles, toys, and parts of sink faucets
Centrifugal Casting
- Uses centrifugal force to produce parts with better surface finish than sand casting
- Suitable for high-volume production runs and offers good mechanical properties
- Limited to smaller castings with good mechanical properties, low shrinkage, and low gas porosity
Permanent Mold Casting
- Offers precise control over dimensional attributes and repeatable casting process
- Has high tooling cost, long set-up time, and limited to smaller castings
- Higher pouring temperature of molten metal reduces mold life
- Only suitable for materials with lower melting temperatures
- Limited part geometry due to mold opening and closing
- Offers good surface finish, reusable mold, and fast cooling rates
Slush Casting
- Has varying wall thickness, requires manual labor, and is time-consuming
- Suitable for producing gold jewelry, lamp components, and hollow parts
- Mainly used for manufacturing brass materials items
