Aluminum Die Casting Parts vs Plastic Injection Molded Parts.

Plastic Injection molding and aluminum die casting are similar in a lot of ways:

• Both require a mold or tool to produce parts.
• The tooling cost is very similar in both industries.
• Both processes inject material into a mold to make parts.
• Both processes can make hundreds or thousands of parts every day.

Plastic Injection Molded Parts
Advantages

• Plastic parts are produced at a lower temperature than aluminum parts, plastic melts at only a few hundred degrees Fahrenheit
• Plastic Parts weigh less than aluminum die casting parts.

Disadvantages:

• Plastic is not typically biodegradable
• Plastic parts require metal inserts to hold a thread for screws.
• Plastic does not block EMI/RF waves
• Plastic Parts are not as strong.

Aluminum Die Casting Parts

Disadvantages

• Aluminum parts weigh more than plastic.
• Aluminum parts are produced in only one color and need paint or powder coat for color.

Advantages

• Aluminum naturally shieds EMI/RF waves.
• Holes can be directly threaded into the parts.
• Features can be machined into aluminum.
• Aluminum has great thermal transference properties.
• Aluminum is a natural conductor of electricity.
• Aluminum material is environmentally friendly and can be recycled easily when done.
• All aluminum alloys (360, 380, 383, and 413) are made from recycled materials.
• Aluminum parts are stronger than plastic
