Extrusion Profile

Profile Extrusion -In the profile extrusion process, polymer granules are melted via a screw rotating within a heated barrel. The external heat combined with frictional (shear) heat of the the granules rubbing against each other melts the polymer as it is driven towards the exit of the barrel. The molten polymer is then forced along heated pipes until it reaches a steel die where the profile shape is formed. The die is designed to gradually change the flow of polymer from a continuous "rod" of polymer flowing in a heated steel pipe to the final profile required. After exiting the die the polymer profile is then cooled to fix the dimensions in a series of water baths which bring the temperature down to ensure a solid profile. This profile can then be cut into fixed lengths. Examples of extruded profiles are window frames, sealing profiles for automotive doors/windows/trims, bathroom & kitchen sealing strips, as well as a number of industrial applications.
