Are considering whether you can use the right kind of plastic for making the 2.4meter x 0.5m x 0.4 meter cast.
Now I compare the aluminium metal and plastic
- The Flatness : aluminum is better ,and stability.
- the strenghness :aluminum is more durable and more tensile strength.
- the cost ,the plastic part is cheapest ,The tooling also cheap than die casting aluminium
- The heatsink:aluminium raise cooling effciency,add external aluminium radiating rib for dissipate heat quickly
- if you have choose aluminum with limited money . you can choose sand casting for small patch .and die casting aluminium tooling cost is highest , but we can use extrusion service or stamping instead of it
