文摘
- •
Micro-injection molding of a micro-pillared surface for biomedical application
- •
Relation between cavity design and state-of-the-art micro-injection molding technologies
- •
A smaller cavity thickness increases the replicated height of micro-features.
- •
The application of vacuum venting has no significant effect on the replication.
- •
The holding pressure can be effectively exploited to improve the replication close to the injection location.
