STX manufacture a wide range of aluminium components for various industries with machine tonnage ranging from 135 ton up to 900 & 1250 ton. Pressure die-casting is a process where molten metal alloy is injected under high pressure into a steel mold (or tool), and solidifies rapidly (within milliseconds) to form a net shaped component and is then automatically extracted.
The die casting tool will typically produce any number of components from hundreds to thousands, before requiring replacement.
Advantages of die casting:
- Excellent dimensional accuracy (depending on casting material, but usually 0.1 mm for first 2.5 cm (0.005 in for first inch) and 0.02 mm for every extra centimeter (0.002 in for every extra inch).
- Smooth cast surface (1-2.5 micrometer or 0.04-0.10 rms thou).
- Thin walls can be cast compared to sand and permanent mold casting (around 0.75 mm or 0.030 years). Inserts can be cast-in (such as threaded inserts, heating elements, and high surface bearing strengths).
- Reduce or eliminate the operation of secondary machines.
- Rapid level of production.
- The pull strength of Casting is 415 MPa (60 ksi).
Casting made 8 meters and 30Lbs by weight. In magnesium.
Disadvantages of die casting:
- Weight Casting should be between 30 grams (1 ounce) and 10 kg (20 lb).
- High initial cost.
- Limited for high fluidity metal.
- A certain amount of porosity is common.
- A large volume of production is required to make economical alternatives for other processes.
