Injection molding machine with viscosity gauge and method to measure with an injection molding machine

摘要

In the case of an injection molding machine is a nozzle via a the nozzle adapter connected with the heating cylinder. A pressure measurement probe is mounted on the nozzle adapter. Molten plastic is mixed with the front an open nozzle in air and a calculate plastic pressure occurring is sprayed with a pressure measuring unit during the injection molding of the molten plastic material in the air is measured. On the basis of the measured pressure, the viscosity of the sprayed molten plastic material is determined.
