Actually making the extruded profiles work exactly according to the desired parameters is not an easy task. Improving the extrusion profiles calls for both innovation and using latest techniques. The process to have an improved working of the extruded profiles may start from the process of profile designing to using techniques for better surface finish.

Parameters for Perfect Extruded Profiles
Irrespective of the material that is used in the manufacture of extruded profiles, the features and properties that are expected from an improved extruded profiles remains essentially the same. Some of these parameters are:

• Close tolerances
• Resistance to corrosion
• Capacity to withstand various climatic conditions
• Excellent surface finish
• Excellent strength
• Light weight especially in aluminium extruded profiles

Techniques for Improving Extruded Profiles
Some of the techniques that are there for improving the extruded profile's performance is given below. Most of these performance enhancing techniques are limited to the profiles made of aluminium, while the section on "Reinforced extruded profiles" takes a look at plastic profiles.

• Design of Extruded Profiles
• Hydroforming
• Friction Stir Welding
• Reinforced Extruded Profiles
• Surface Finish
