G.James specialises in the design, manufacture and supply of a range of custom made flexible, rigid, semi-rigid and nitrile modified Polyvinyl Chloride (PVC) profiles.
What is PVC Extrusion?
PVC Extrusion is a process whereby pvc compound (polyvinyl chloride ) is fed into a extruder via a hopper.
The extruder itself consists of a barrel and a screw inside the barrel. The PVC compound is conveyed through the barrel by the flights on the screw.
The material is heated as it is fed along the barrel by heater bands wrapped around the barrel and the material is compressed by the design of the screw profile.
This heat and compression converts the pvc into a molten compound which is then forced through a die orifice. The die is mounted onto the front of the extruder and the orifice helps determine the shape of the profile.
