Downstream Extrusion Equipment

Downstream extrusion equipment is used to finish and inspect parts after they have been extruded. Post-extrusion processing operations include cooling, cutting, pulling, texturing, embossing, and inspection. Downstream extrusion equipment is designed to process and finish all kinds of extruded products, including plastic and metal piping, rods, or wires; rubber hoses and gaskets; aluminum and steel; and other types of metal sheet. Suppliers of downstream extrusion equipment differ in terms of capabilities, cost, and service

. Downstream extrusion equipment is often used to prepare extruded parts for assembly, finishing, painting, labeling, or shipping. Downstream extrusion equipment may also include inspection processes to ensure that extruded parts meet specific industry standards, such as ISO 9000 standards. Different extruded products may require different downstream extrusion equipment for various finishing processes. For example, downstream extrusion equipment that is used to finish plastic extrusion products may include saws and cutters, punches, and cooling equipment. Cutting equipment such as a laser cutting machine is used to cut various lengths of extruded plastic pipe or tubing. Rubber extrusion products often require finishing in salt tanks or infrared ovens, and may also be cut into smaller components.

Downstream extrusion equipment for aluminum or other metal extrusion products include cutting and embossing equipment. Aluminum extrusion products include sheets that are cut or punched by an extrusion die cutting machine, formed and bent into long sections that are then further processed by a metal cutting machine into smaller pieces. Aluminum extrusion products are used extensively in building and construction, transportation, and aerospace applications. Aluminum extrusions may be finished with specific textures by an embossing machine. An embossing machine impresses a pattern on the aluminum by passing it through a series of textured rollers.

• Extrusion Processes
  Extrusion is the process where a solid plastic (also called a resin), usually in the form of beads or pellets, is continuously fed to a heated chamber and carried along by a feedscrew within. The...
