Plastic Parts Injected Molded | Plastic Comparison
Similarities Of Plastic Injection Molded Parts and Aluminum Die Casting Parts. Plastic injection molding and aluminum die casting are similar in a lot of ways:
- Both require a die, a mold or tooling to produce parts.
- The dies or tooling costs are very similar in both industries.
- Both processes inject material with pressure into a mold or die to make parts.
- Both processes can make a few parts, hundreds of parts or thousands of parts every day.
- 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.
- 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
- Aluminum die casting parts are stronger than plastic but aluminum parts weigh more than plastic injection molded parts.
- Aluminum parts are produced in only one color and need paint or powder coat for color. Aluminum can be polished or anodized.
- Aluminum naturally shields EMI/RF waves to protect electronic circuits.
- Holes can be die casted in the parts and directly threaded into the aluminum parts.
- Features can be machined into aluminum and the part remains strong.
- Aluminum has great thermal transference properties and is used for heat sinks.
- Aluminum is a natural conductor of electricity and can be e-coated or used as an electrical ground for electronics.
- Aluminum material is environmentally friendly and can be recycled easily when done. Die casting materials are all recycled materials that were alloyed into a die casting aluminum alloy. All aluminum alloys (360, 380, 383, and 413) are made from recycled materials.
