The present invention relates to a method of manufacturing a vaginal ring, wherein the vaginal ring comprises at least one therapeutically active agent and a body comprising a crosslinked siloxane elastomer. The method comprises manufacturing the body in the form of a rod having a first end and a second end and forming the body into a ring by arranging an attachment part between the first end of the body and the second end of the body, wherein the attachment part comprises a non-crosslinked siloxane elastomer having a weight average molecular weight of 650-850 g/mol and a cross-linking catalyst, and curing the attachment part for a period of time of 1-30 second using a temperature of 125-220°.
