Abstract
The present invention is directed to devices for encapsulating medicinal products and methods of using these devices to form the encapsulated product. More specifically, the present invention includes improved closing and/or ejection pins for use with a conventional capsule closing device. The closing pins may be hollow down a longitudinal interior diameter and may include a chamfered capsule contacting surface. The closing and/or ejection pins may be removably mounted to a pin plate and may be manufactured from a polymer. The pin plate may be attached to an actuation shaft in a non-rotational fashion, such as with a non-circular shaft profile and set screw.
