Description
In a general sense, all shaped or configured extrusions are profile extrusions, whether tubular or another geometric cross-section in form. Any extrusion that is not a flat sheet or film product is often referred to as a profile extrusion.

What is plastic extrusion
The raw material (polymer) in the form of granulates, is gravity fed into the hopper and through the feed throat, drops on a rotating screw. Screw rotation is provided by an electric motor. The screw design varies and is dependent on the material and final product design. The rotation of the screw forces the plastic forward through a heated barrel. As the plastic is conveyed through the barrel the channel or thread of the screw decreases, thus compressing the plastic. Three or more independent Proportional Integral Derivative PID controllers, creating zones of gradually increasing temperature, heat the barrel. The plastic melt temperature is normally higher than the set temperature for the controllers. This additional heat is generated through a combination of compressive force and shear friction (shear heat). When the plastic melt reaches the end of the screw the plastic melt is well mixed and pushed through a screen pack, supported by a breaker plate, filtering contaminants and removing the materials rotational memory. Finally the filtered melt is then pushed through the die. The die gives the final product the desired profile and shape. After exiting the extruder the extrudate is pulled and cooled. The cooling method is dependent on the profile and shape of extrudate.
What is PVC density?
- PVC is chemically stable and does not de-polymerize.
- Density: 1.6 g/cm3
