What’s differences between Injection Molding and Blow Molding?
There are several significant differences between injection molding and blow molding:
1. manufacturing process itself
2. tolerances and margins of error
3. design considerations
4. role of the process for intended result
5. Main difference between injection molding and blow molding:
6. Injection molding – produces a part that is solid such as a reusable coffee cup lid
7. Blow molding – produces hollow parts such as water bottles
8. The blow molding process can produce plastic parts with very complex shapes. However to achieve this the wall thickness may vary from place to place depending on how much the material has to stretch when it is being blown. The thickness of a plastic part created through injection molding is determined by the relationship of the mold and the core.
However, if you will be farther ahead if you are able to determine the best molding process for your plastic product in the product development stage.
