Hinges: Some materials tolerate repeated bending and can be used as hinges. In other cases, profiles can be co-extruded from hard thermoplastic and elastomers, which gives optimal flexibility.
Seals: Profiles with integrated sealing strips can have major advantages in installation, such as in building and industry.
Coatings: In the form of thermal stamping, where the surface is subjected to pressure and/or a structure, or through the application of film with adhesives.
Decoration: Using a line pattern in the extrusion tool.
Screw pockets: They provide the profile with good attachment points, regardless of the length to which it's cut.
Sliding function: Some polymers have a very low friction coefficient. These polymers can be used for durable products such as conveyor belts.
Joining keys: The profile can be designed for joining with other profiles, machine components, building components, etc., without the use of adhesives or extra parts.
Spring action: Can be achieved through the right choice of materials. Many plastics are de-stressed so the spring action decreases over time.
Friction: High friction can be achieved through co-extrusion with a rubber-like elastomer. This is used in architraves, for example.
Marking: With a barcode, sorting declaration or company name, for example, applied with inkjet printing.
Encapsulation: Reinforcing wires, etc., can be inserted in the profile during extrusion. Soft sealing strips can be fitted with a cord, for instance, which prevents the strip from overstretching during installation.
Colouring: Most types of plastic can be coloured. When 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.
Snap-on: Can simplify fitting and replacing screws or bolts.
Grooves: For inserting sealing strips, for instance.
Fixing: Guides and fixings can be designed so the product only works within specific dimensional deviations. This enables extremely precise tolerance ranges.
Insulating cavities: In structures, to counteract cold bridges such as door and window profiles.
Reinforcement: Ribs at exposed places can be a cheaper alternative to increasing the material thickness.
