Abstract
An apparatus for extrusion molding that includes an extruding die that permits extrusion of a material into a hollow tubular molding, a molding die, first and second clamping devices and a device for releasing compressed air. The first and second clamping devices are positioned along opposite end portions of the molding die and configured to clamp the molding independently from one another to form an air-tight space therebetween. The molding die includes two die cavity halves and is arranged to close around the air-tight space and compress the molding to conform the same to a final product configuration. The device for releasing compressed air is arranged to release compressed air before the die cavity halves are separated.
