2C injection molding and encapsulation of inserts – Openair® Plasma ensures impervious, secure bonds
When
manufacturing medical devices, only a limited number of certified
source materials may be used, so material combinations are
complicated, in particular for 2C injection molding. Activation with
Openair® Plasma facilitates secure adhesion at the hard/soft
interface, however, making it possible to nonetheless extrude
non-compatible starting materials with each other.
Plasma cleaning of components for a heart-lung machineA
secure bond is also important when encapsulating inserts. In
manufacturing inserts, for instance, the insert is placed in the die
and it is encapsulated with polycarbonate. Pre-treatment with a
potential-free, cycled Openair® plasma jet provides micro-fine
cleaning of these metal inserts prior to injection molding.
The
plasma energy simultaneously activates the surface, which ensures an
absolutely impervious bond between the metal and the polycarbonate
sheathing.
