摘要： An apparatus for manufacturing a hollow plastic product is provided. In accordance with one aspect, into a mold half having a tubular groove portion and a projecting groove portion which projects outwardly from the tubular groove section is supplied a parison into the tubular groove portion and a clump of molding material into the projecting groove portion. When blow molding is carried out by introducing a pressurized gas into the parison, the clump becomes integrated with the parison thereby providing a hollow plastic product of unitary structure. In accordance with another aspect of the present invention, a parison extrusion nozzle is provided with at least two passages each of which is connected, preferably through a valve, to a corresponding dispensing unit for dispensing a desired molding material. A control unit is provided as connected to each of the dispensing units to control the supply of molding material so that there is obtained a parison having regions of different molding materials.

摘要： An extruder having an extruder head that forms a tubular passageway, an extruder screw rotatably disposed in the tubular passageway, and a first motor connected to the extruder screw for rotating that screw to force an extrudable material through the tubular passageway. The extruder further has a feed hopper for holding the extrudable material, and having an outlet in communication with an inlet of the extruder head for conducting the material thereinto. The feed hopper defines a supplemental opening adjacent the inlet of the extruder head, and a feed assist roller is rotatably supported on the extruder and extends partly through this supplemental opening to a location adjacent the inlet of the extruder head. A second motor is connected to the feed assist roller for rotating that roller to facilitate moving the extrudable material from the feed hopper and into the tubular passageway of the extruder head.

摘要： A device for feeding an extrusion head for plastic material includes a main extruder connected to a main die for extruding a continuous main flow of material, and an auxiliary feed mechanism associated with the main die and selectively controlled to cover the outer exit flow of the main die with a surface layer. The auxiliary feed mechanism continuously conducts two auxiliary flows, a first flow forming the surface layer and the second flow being mixed with the main flow. An invertor valve permits selective exchanging of the two auxiliary flows such that the second flow can cover the main flow and the first flow can be mixed with the main flow.

摘要： The invention provides a method for encapsulating extrudable materials within an extruded stream of another extrudable material. The produced product is an extruded material that contains one or more different materials embedded within the first material. The boundaries between this first encapsulating material and the material or materials thus encapsulated are well-defined and distinct. In the preferred embodiment, the encapsulated and encapsulating materials are plasticized thermoplastic resins. A stream of the encapsulating material is formed in a first extrusion channel. A plasticized stream of the material to be encapsulated, coated by a coextruded layer of the encapsulating material, is simultaneously formed and travels through a second extrusion channel. At any selected time, a cross-sectional segment of the second stream may be removed from its stream and replaces a similar cross-sectional portion of the stream removed from the first channel. The resulting stream of material extruded from the first channel contains discrete and uniformly shaped units of the second material encapsulated within a continuous stream of the first material.

摘要： A vertical plastic parison extruder with a relatively short vertical height and an adjustable choke between the extrusion screw and the extrusion die. The choke, in combination with a vertically moveable mandrel extending into the extrusion die, frictionally dissipates the rotational component of the moving viscous plastic between the extrusion screw and the exit of the extrusion die. The relatively short length and large diameter of the extrusion screw permits the moveable mandrel to extend through the extrusion screw and eliminates the need for lateral support of the extrusion screw and mandrel below the material feed entrance to the extrusion screw. The extrusion screw length to diameter ratio is adjusted to provide the same residence time for plasticizing the feed material as with the normally smaller diameter and longer extrusion screws.

摘要： A mini-extruder apparatus for extruding small quantities of material. The apparatus is designed to overcome the problems of excessive heat transfer from the heated portion of the barrel to the feed portion of the extruder barrel and the premature failure of the long thin extruder screws employed in extruders. The mini-extruder includes an extruder barrel having a substantially circumferential, radially extending cavity formed in an isolator portion of the extruder barrel to thermally isolate the feed portion from the heated portion. The mini-extruder also includes a drive system constructed to drive the extruder screw at both ends. The mini-extruder can also be designed as a co-rotating or counter-rotating twin screw extruder where each end of each extruder screw is driven.
