Abstract
A co-injection nozzle is disclosed that includes a combining means configured to reduce shear heating and create a more even shear heating profile in core and skin material flow streams. The combining means is configured to reduce shear heating peaks and valleys in core and skin material flow streams as the streams flow between annular channels of the combining means during a mold filling process.
