Document Type and Number:
Japanese Patent JP2022087515
Kind Code:
A
Abstract:
To grasp viscosity of a resin easily regarding an effective technique when applied to a viscosity estimation technique estimating viscosity of a resin.SOLUTION: A viscosity estimation device 100 comprises a viscosity estimation part 303 estimating viscosity based on a melt-flow rate. The viscosity estimation part estimates the viscosity based on the following Formula 2; where, η: viscosity, C: constant, MFR: melt-flow rate, dγ/dt: shearing rate, n:constant, α:constant, T:temperature.SELECTED DRAWING: Figure 3
