Extrusion - Designoptions
 
  1. Hinges Some materials tolerate repeated bending and can be used as hinges. In other cases, profiles can be co-extruded from hard thermoplastic and thermoelast, which gives optimal flexibility.
  2. Seals Ideal for seals. Profiles with integrated sealing strips can have significant advantages in terms of installation, e.g. in building and industry.
  3. Coatings - either in the form of thermal stamping, where the surface is subjected to pressure and/or a structure or through the application of film using adhesives.
  4. Decoration using a line pattern in the extrusion tool.
  5. Screw pockets means that the profile has good attachment points regardless of the length to which it is cut.
  6. Sliding function. Some polymers have a very low friction co-efficient. These polymers can be used for durable products, e.g. for conveyor belts.
  7. Joining keys. The profile can be designed so that it can be joined to other profiles, machine components, building components, etc. without the use of adhesives, etc.
  8. Spring action can be achieved through the correct choice of materials - many plastics are de-stressed, so that the spring action decreases over time.
  9. Friction. High friction can be achieved through co-extrusion with a rubber-like thermoelast. This is used in architraves for example.
  10. Marking e.g. with a barcode, sorting declaration or company name, applied using ink jet printing.
  11. Encapsulation. Reinforcing wires, etc. can be inserted in the profile during the extrusion process. Soft sealing strips could for example be fitted with a cord, which prevents the strip from being overstretched during installation.
  12. Colouring. Most types of plastic can be coloured. Where there are particularly demanding requirements for precise colours, pre-coloured granulate is used or a percentage of coloured granulate is introduced during the extrusion process.
  13. Snap-on can simplify fitting and replacing screws or bolts.
  14. Grooves e.g. for inserting sealing strips.
  15. Fixing. Guides and fixings can be designed so that the product only works within specific dimensional deviations. This enables extremely precise tolerance ranges.
  16. Insulating cavities in structures to counter cold bridges, e.g. door and window profiles.
  17. Reinforcement using ribs at exposed places can be used to good effect instead of increasing the thickness of the material.
