Profile Extrusion is accomplished by forcing molten plastic through a die to form a part with a uniform cross section. This extrusion is then cooled to solidify the plastic. This can be done with multiple plastics simultaneously to form parts that have different properties in different areas of the cross section.
 

Process Characteristics
Part Cost - low Tool Cost - low Production Capability - high Short lead times to production Uniform cross section of parts Multiple materials / durometers are possible in the same part.
