METHOD FOR CONTINUOUS FRICTION-ACTUATED EXTRUSION |
摘要 |
In a continuous friction-actuated extrusion process, such as the Conform process, particulate material is fed into the extrusion passageway at a rate low enough to the rate at which material is extruded from the die orifice to be determined by and substantially equal to the rate of feeding. Feeding can be achieved by a simple hopper feeding through an adjustable constriction, preferably formed by a simple gate valve, or a gravimetric or volumetric controlled rate feed device can be used. |
