  • Patent number: 10076867
    Abstract: A device and a method for producing a preform having a shoulder and base geometry optimized for subsequent stretch blow molding, since the preform cannot be produced according to the conventional injection-molding method. For this purpose, the preform produced in the injection-molding tool is transferred into a conditioning station and is conditioned and cooled in the shaft while no contact is made with the top of the preform and the preform shoulder on account of a special contour of the conditioning receptacle. Due to the reheating of these preform regions they can be mechanically deformed into a new geometry which is advantageous for the blow molding process and thus their wall thickness can also be influenced. In the subsequent blow molding process the deformed preform has the advantage that the plastic material which is distributed better in the bottle results in considerable material savings and higher quality bottles.

The system also includes a controller coupled with the extruder, the controller configured to apply a correction factor that has been calculated for a path of the nozzle based on a slope of a surface of an object to be fabricated. The correction factor for a positive slope is different from that for a negative slope. The extruder is configured to cause movement of the nozzle along the path to deposit material on the slope of the surface of the object, and the correction factor removes differences in thickness of the deposited material caused by the slope in relation to the path.

  • Patent number: 9108350
    Abstract: The present invention provides blowing agent introduction systems and methods for introducing blowing agent into polymeric foam processing systems. The methods may involve introducing one or more doses of blowing agent into polymeric material in an extruder during a plastication period of a molding cycle. Prior to introduction, a dose is confined in an accumulator which, for example, has a volume defined between an inlet valve and an outlet valve. A control system may receive inputs related to system parameters (e.g., pressure of polymeric material in extruder, axial position of screw in barrel, whether screw is rotating, and the like) and based on the inputs coordinates operation of the valves to confine and introduce the blowing agent dose(s). The introduction systems may be used in discontinuous plasticating processes, such as injection molding and blow molding, and can be particularly useful in processes that use precise quantities of blowing agent.

    Abstract: A thermoplastic compound is formed using a blend that includes one of processed fly ash, cinders and processed fly ash and cinders with a fractional melt having a melt flow index of less than 1 or a low melt resin with a melt flow index between 1 and about 3 or both, and a resin compatible with the fractional melt or low melt resin and having a melt flow index that is different from the melt flow index of the fractional melt or the low melt resin. Presence of the processed fly ash and cinders is believed to reduce cycle time for forming the thermoplastic compound into a plastic product from about 5 percent to about 30 percent merely because of the presence of the processed fly ash and cinders. Presence of the processed fly ash and/or cinders also permits the increased use of more fractional melt than conventionally attempted and also allows for use of thermoplastic regrind from recycling sources.

    Abstract: Stretch film is treated by passing a web of tackifier-containing, unbloomed thin polymer film through a heater so that the web is heated to a temperature sufficient to cause tackifier bloom prior to the web reaching a next stage in an in-line process. Also, a pattern can be applied to a thin polymer film. An oriented web of thin polymer film is passed across at least one heated roller having the pattern engraved thereon to define face regions and relief regions collectively conforming to the pattern. As the web contacts each roller surface, portions of the web positioned over the relief regions receive less heat than portions of the web positioned over the face regions, thereby causing the respective portions of the web to undergo differential, heat-induced shrinkage which imparts the pattern to the thin polymer film.

  • Patent number: 8641951
    Abstract: The invention relates to a method for producing a programmed shape memory polymer, which assumes a first temporary shape and at least two additional stored thermally activatable shapes, namely at least one second temporary shape and a permanent shape, with the steps of: (a) providing a shape memory polymer which has at least two switching segments (A, B), which through phase segregation each form a switching phase having each a corresponding transition temperature (TtransA, TtransB), (b) deforming the shape memory polymer into a shape corresponding to the first temporary shape at a temperature above the upper transition temperature (TtransA), and (c) cooling to a temperature below the lower transition temperature (TtransB) by fixing the first temporary shape. The method of the invention provides a one-step programming method for a triple-shape plastic material.

  • Patent number: 8608999
    Abstract: A method of fabricating a three-dimensional geometrically complex device is provided, based on a shape memory polymer. The method includes selecting a substrate composed of a shape memory polymer. A filling material is deposited in or on a planar surface of the substrate, thereby forming the device. The planar surface of the substrate may be in either a temporary or original shape of the substrate. Prior to the deposition of the filling material, the substrate is transformed into a first shape having a planar surface if the original shape of the substrate does not have a planar surface. The device is configured to be thermo-mechanically tunable to display a plurality of geometrically complex shapes, under a series of temperature changes and stress.

  • Patent number: 8591789
    Abstract: In a belling machine and in a method of forming a socket at the heated end of a pipe made of thermoplastic material, an end (20) of a pipe (2) made of thermoplastic material on which a socket is to be formed is heated until it is in a deformable state, inserted in a forming chamber (1) and formed into a socket shape. Process air, taken from a compressed air source (30), is conveyed by a process air feed line (3) into an evaporator (40) of a refrigerating machine (4) using a refrigerant recirculating in a closed circuit and passes through the evaporator (40), resulting in transfer of heat from the process air to the refrigerant inside the evaporator (40). The process air treated in this way in the evaporator (40) is then conveyed by the process air feed line (3) to the forming chamber (1) into which it is introduced through an inlet (10), at least to cool the material of the end (20) of the pipe (2) at least by means of a process air flow inside the forming chamber (1).

    Abstract: A method and system for making a golf ball core is disclosed. The method may generally include forming a golf ball core out of a raw core material. The golf ball core may be rapidly heated to begin curing (or vulcanizing) from the outermost surface toward the center of the golf ball core. Before curing the entire golf ball core, the golf ball core may be quenched to stop the curing process. As a result, the golf ball core may include an outer cured zone and an inner uncured zone. In this state, the golf ball core may be incorporated into a finished golf ball to be sold to consumers. Following a set of instructions provided with the golf ball, the consumer may heat the golf ball and a cure indicator to customize the properties of the golf ball core, and, thus, the characteristics of the golf ball.

    Abstract: A method of forming an article of footwear includes injecting a first material into a first cavity of a mold assembly to form a sole assembly, injecting a second material into a second cavity of the mold assembly, a first last being suspended within the second cavity, to form an upper of the article of footwear about the first last. The upper and the sole assembly are positioned in contact with one another. The upper and the sole assembly are cured and bonded together to form an article of footwear. The article of footwear is removed from the mold assembly and from the first last and allowed to expand to a first size.
