Abstract:
1. A method for welding two separate extrusion ends of a thermal plastic material to form a flashless article comprising: a) spacing a first and a second extrusion end to a first position extending beyond a respective first and second mold and residing at said first position by contacting a stop; b) removing said stop from said first position; c) inserting a heating element between said first and second extrusion ends; d) heating said extrusions to a temperature for welding; e) compressing one of said extrusion ends into one of said molds; f) plunging said compressed extrusion end into the other of said molds until contact is made with the other extrusion end; g) compressing the other of said molds upon said other extrusion end; and h) cooling the molds to a temperature, thereby forming a flashless article.
