2008-9-2 The pressure developed in the extruder system is largely a function of die resistance and dependent on die geometry and melt viscosity. Extrusion pressures are lower than those encountered in injection molding. They are typically 500 to 5000 psi (3.5 to 35 MPa). In extreme cases, extrusion pressures may rise as high as 10,000 psi (69 MPa).

2019-4-12 Introduction High pressure intrusion–extrusion of nonwetting liquids into porous solids is a promising technology for mechanical energy absorption and storage. 1,2 This principle of energy absorption proposed by V. Eroshenko is based on the conversion of the applied mechanical energy into the energy of solid–liquid interfaces by forced penetration (intrusion) of a nonwetting liquid into ...

2015-9-23 higher extrusion temperatures. It should be remembered that pressure can influence flow properties. Two resins may have the same MI, but different high pressure flow properties. Therefore, MI (Table 2) must be used in conjunction with other yardsticks, such as molecular weight distribution, to measure flow and other properties of resins.
