Measurement of injection flow length using spiral flow.
We measure the resin flow length when injection molding is performed under certain conditions. The mold is designed with a resin injection port at the center, and a spiral groove with a constant spacing based on an Archimedean spiral is used. A flow velocity meter is incorporated within the cavity to measure the flow velocity immediately after injection. Additionally, a flow velocity sensor installed in the mold allows for the determination of the initial flow velocity into the cavity, as well as the shear rate and shear viscosity at the time of passing through the sensor. [Features] ■ Capable of calculating shear rate and shear viscosity during cavity passage ■ Allows comparison of flow length and shear viscosity *For more details, please download the PDF or feel free to contact us.
