Plastic is not metal

Plastic is not metal

1. Plastics show changes in their mechanical properties at room temperature or if they are exposed to stress

2. Many plastics designs are delivered from metals

3. Basic properties of plastics form a very marked contrast to those of metals

4. PLastics are less tolerant than metals

5. A well designed object can fail if the material is exposed to inappropiate conditions

6. PLastics have different behavior than metals even if they are exposed to the same device

7. You must do a thorough and precise analysis of all requirements before every design process
