Topic: Two-component (2C) injection molding in medical technology. Plasma activation prior to encapsulating metal inserts.

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.

A 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.
