Extrusion Profile

Profile Extrusion of thermoplastics stands as a cornerstone in creating uniform, long, continuous shapes, pivotal across various industries.

Understanding Profile Extrusion:


  • Material Preparation: Thermoplastic granules are processed through a heated Archimedean screw that melts and homogenizes the material.

  • Continuous Operation: This method facilitates the production of extended product lengths without interruption.

  • Constant Cross-Section: The extrusion yields profiles with a consistent cross-section, essential for products like curtain tracks, skirting boards, and conduit.



Mechanics of the Process:


  • Motor and Drive System: An electric motor paired with a hydraulic drive rotates the screw within the extruder’s barrel.

  • Material Feeding: Plastic granules enter through a hopper, drawn and melted by the barrel's heat, and then pushed through a die shaping the profile.

  • Cooling Bath: The molten profile passes through a water bath with formers and guides, where it cools, solidifies, and assumes its final shape.

  • Temperature Regulation: A controlled water circuit or process chiller ensures the bath maintains a consistent temperature for optimal cooling.



Speed and Quality Control:


  • Take Off Rollers: These adjustable rollers draw the profile at the correct speed, affecting its dimensions post-cooling.

  • Vacuum Calibration: Ensures high-precision, hollow profiles maintain dimensional accuracy via a vacuum that molds the soft extrudate within the cooling bath.



Post-Extrusion Handling:


  • Cutting to Size: Profiles are cut for transport and application specifics, with flexible types coiled and rigid types sawed or guillotined.

  • Measurement: A counter, activated by a roller contacting the extrusion, ensures accurate length measurement.



Advanced Techniques:


  • Co-Extruded Profiles: Combining different materials or colors, twin head extruders, and custom dies allow for multilayered profile extrusions, where separate melts bond upon exiting the die.



Materials and Products:


  • Typical Materials: HDPE, PVC, ABS, PA are often used in profile extrusion.

  • Product Range: Includes items like land drainage tubing, cable harnesses, door seals, and various sections for household and industrial applications.


Profile extrusion is integral to manufacturing a diverse array of products, offering customization in design and functionality while ensuring material efficiency and durability.
