What is Profile Extrusion?


Plastic Extrusion is a manufacturing process through which plastic is melted, shaped into a continuous profile, and cut to length. This process is used in the production of a wide variety of items, including piping, wire insulation, and plastic sheeting. Even adhesive tape and window frames include extrusion as part of their manufacturing processes.

Advantages of Profile Extrusion:

  • Low scrap rate
  • Less purge
  • Close tolerances
  • Consistent melt
  • Continuous process
  • Stronger physical properties
  • Less brittleness
  • High margins
  • Usage of custom color resins
  • Extrusion dies are more economical than injection molds
  • PVC replacement
  • Stronger physical properties

Q. What is the profile extrusion process?
A. Profile extrusion is a process that forces heated resin through a die. The material assumes the configuration of the opening geometries in the die to create a continuous, uniform shape. After fully exiting the die, the profile is cooled in a water bath. It can then be cut into desired lengths.. Extruded profiles can be made with high-impact polystyrene (PS), polyvinyl chloride (PVC), high-density polypropylene (HDPP), acrylonitrile butadiene-styrene (ABS), thermoplastic elastomers (TPEs) and other materials. Profile extrusion does not include production of plastic sheet and film
Q. What are the top profile extrusion applications?
A. Window and door frames and gutters often use PVC profile extrusions. Another building and construction application is PVC siding. On the interior, window blinds are often made with extruded profiles, which can be given different surface textures from the die. Materials offering thermal stability and good electrical properties can be used to extrude wire and cable insulation and jacketing. Thermoplastic elastomers can be used for flexible profile extrusion such as weatherstripping and tubing.
Q. Why is extrusion molding used?
A. Extrusion offers the advantages of high-volume, high-speed continuous production and minimal waste. It produces complex shapes, various profile thicknesses and different textures with consistency and precision. Furthermore, the tooling tends to be less expensive than tooling for other polymer manufacturing processes.
