Abstract
An extrusion molding process including the steps of: i) extruding a material through an extruding die into a tubular molding, ii) driving two clamping devices to clamp the tubular molding at different elevations, causing an air-tight space to be formed within the tubular, iii) closing two symmetrical halves of a molding die on the molding between the clamping devices and simultaneously lowering one clamping device to stretch the molding downwards, causing the molding to be compressed in a die cavity between the two symmetrical halves of the molding die and molded into the desired finished product; and iv) opening the molding die from the finished product and returning the clamping devices to their former positions.
