Hormone ring

Before the injection moulding process, an active ingredient that protects against HIV is mixed into hormone rings made of LSR. Clean room production meets the highest standards of hygiene and product quality.


HIV protection: A production cell around an electric ALLROUNDER 520 A mass produces active ingredient implants made of LSR.


The electric injection moulding machine in stainless steel version is specially designed for clean room applications.


As primary contractor, ARBURG bears responsibility for the complete production cell. This operates directly in a clean room.

Whatever the requirement.
We'll find the solution.
