摘要: In an extrusion die flow channels supply molten plastic to a pair of distribution grooves constructed in the upstream face of the die component adjacent to the die body. The die body becomes more universal and can be used for a variety of applications by replacing the die component with alternate designs of distribution grooves.

摘要: The invention relates to an extrusion die assembly having a balanced flow path in which the die and tip modules cooperate to form an extended exit channel which communicates with an extrusion channel. The die is rotatably mounted on the die holder and the tip module is rotatably mounted within the axial bore. Each of the rotatably mounted components is independently driven by a motor. The motors are controlled to provide an infinite variation in relative rotational motion between the rotating components.
