Rubber Extrusion: Drag, Pressure and Leakage

April 8, 2023

Drag, pressure, and leakage are important factors that affect the quality of the extruded rubber product in the rubber extrusion process. Drag: Drag refers to the frictional force that occurs between the rubber material and the surface of the extrusion die or head. The drag force opposes the movement of the rubber material and is

Rubber Extrusion – Line takeoff speed

April 8, 2023

Line takeoff speed in rubber extrusion refers to the speed at which the extruded rubber product is pulled or drawn away from the extrusion die or head. This speed is also known as line speed or haul-off speed. The line takeoff speed is a critical parameter in rubber extrusion as it affects the quality of

Flow behavior of rubber compounds in Extrusion

April 2, 2023

Rubber compounds exhibit unique flow behavior during extrusion due to their viscoelastic properties. When a rubber compound is subjected to shear stress during extrusion, it experiences both viscous and elastic deformation. Initially, the rubber compound behaves as a solid and resists deformation due to its elastic properties. As the shear stress increases, the compound starts
