RFP India is India’s leading manufacturer of aluminium tubes, which are manufactured from high quality hot rolled plates and bars. The Aluminium tubes are extruded by using two likely ways. These are either Porthole extrusion or Seamless extrusion. Well, it is relatively undemanding to differentiate between the two extrusion ways. In porthole extrusion, the mandrel is set and is backed by a number of essential bridges that are attached to the exterior part of the extrusion die. Meanwhile, in seamless extrusion, a mandrel is fixed and positioned within the extrusion die, forming the internal curve of the tube. However,

which production manner is apt depends on alloy and its application. For example, high-strength alloys can merely be produced by seamless extrusion.
