Abstract

The present invention relates to a plunger (1) for feeding encapsulating material to a mould cavity, comprising a closed first and second groove (3) recessed into and enclosing the cylinder casing (6) of the plunger (1), wherein the second groove (3) is positioned between the first groove (2) and the end surface of the plunger (1) to be directed toward the encapsulating material. The first groove (2) is provided with a scraper (5), such that the scraper (5) protrudes at least partially above the surface of the cylinder casing (6) and, optionally, the second groove (3) is provided with a sealing ring (7). The present invention further relates to a kit-of-parts for the assembly of the plunger (1) of the present invention, a device for encapsulating electronic components mounted on a carrier comprising the plunger (1) of the present invention and method and use of the plunger (1) of the present invention.
