TH3630A - Plastic sleeve compression - Google Patents

Abstract

Dispensing the molten plastic material to form a casing around an object where the material is expelled from the outlet of the container (10) by a piston (34) with a resilient, annular polymer seal (50). Which surrounds the piston and attaches to the wall with the receiver of the container The seal joins the plastic material and sweeps the plastic material out of the container. The piston of the OI container is fitted with two flexible ring-shaped polymer seals (50) to cling tightly to the receiver wall and the bearing path (62) arranged in between. Seals to prevent lateral movement of the piston.

Claims (1)

1. Method of compressing as a plastic casing around an object containing The presence of a certain amount of molten plastic material within the cylindrical receptacle of the container and the arrangement of the container with contact with a partially defined cavity by the object to be encapsulated that exhibits characteristic features. That the method also continues Moving the piston (34) along the receptacle to push the material out of the receiver and into the form cavity, while allowing the plastic material to join the ring-shaped polymer flexible seal (50), which surrounds it. The piston is present and is pushed against the wall of the support.
