Patent number: 7022271Abstract: For observing a flow of molten resin in an injection molding apparatus, a transparent cylinder, which is formed of transparent glass or transparent plastic material, is used in place of a mold of the apparatus. Because filling the transparent cylinder with the molten resin up to the cylinder's full capacity will burst the cylinder, the molten resin injection is terminated on the way when the injected molten resin has occupied a predetermined percentage, in a range of 50–90%, of the total volume of the cylinder, so that a burst of the cylinder can be avoided. The transparent cylinder provides for an increased resin-flow observation range because of its transparency, and can be less expensive because it is formed of inexpensive glass or plastic. As a consequence, there can be provided an efficient resin-flow observing experiment apparatus at lower cost.Type: GrantFiled: January 27, 2003Date of Patent: April 4, 2006Assignee: Nissei Plastic Industrial Co., Ltd.Inventor: Masashi Suganuma

When the turret device is in a second position, the second production portion may be used. This approach allows retooling of one of the production portions while the other production portion is running on the line.Type: GrantFiled: January 22, 2001Date of Patent: July 15, 2003Assignee: Crane Plastics Company LLCInventors: Herbert L.

Publication number: 20030090041Abstract: The thermoforming press has a frame, a forming die assembly affixed to the frame, a mold-supporting table suspended to the frame under the forming die assembly, and a pair of molds mounted side by side on the mold-supporting table. A drive system is provided for imparting a pendulum movement to the mold-supporting table for alternately registering one of the molds with the forming die assembly while the other mold is positioned at a part retrieving station. The part retrieving and stacking mechanism has horizontal and angular displacements only as the vertical component of the retrieving motion is provided by the pendulum system. Spring discs are mounted between the forming die assembly and the press platen to control the forces generated between the forming die assembly and each mold.Type: ApplicationFiled: October 24, 2002Publication date: May 15, 2003Inventors: Georg Nemeskeri, Brent B.

Publication number: 20030017224Abstract: The present invention relates to a multiple foam substrate of predetermined shape and a method of manufacturing the substrate. The substrate is a multiple foam substrate which may be manufactured by the method with a mold having first and second mold cavities. The method includes injecting a first foam into the first mold cavity sufficiently to fill the first mold cavity and storing the first foam in the first mold cavity for a predetermined time sufficient to form a substantially non-mixing surface on the first foam. The method further includes injecting a second foam into the second mold cavity and onto the non-mixing surface on the first foam sufficiently to fill the second mold cavity. The method further includes storing the second foam in the second mold cavity for a predetermined time sufficient to bond the first foam to the second foam along the non-mixing surface.Type: ApplicationFiled: September 17, 2002Publication date: January 23, 2003Applicant: Lear CorporationInventors: George B. Byma, Brian A. Cristea, Richard Muhlbacher

Publication number: 20020094353Abstract: A separate parison separation assembly for each parison in a multiple parison blow molding apparatus. Each assembly has a shear plate secured in a recess machined into the mold in order to provide a positive and repeatable location of the shear plate. The shear plate is square and provides eight cutting edges; each of the four sides of the shear plate by rotating the shear plate as an edge wears, and by turning it over. The shear plate has a useful life up to eight times that of the prior art designs. The cut-off knife for each assembly is secured to the other half of the mold, directly on its surface, with a compression pocket cut into the face of this half of the mold to contain and to compress the parison between the mold halves. The design eliminates open space at the edge where the flash forms, reducing the mass of polymer at the edge and thus the temperature of the flash edge.Type: ApplicationFiled: January 17, 2001Publication date: July 18, 2002Inventors: Earle L. Ellis, David A. Kesselman, Bernd Klingenmaier, Jeff Enfield, Roy N. Krohn

Patent number: 6375890Abstract: In an injection blow-molding process the preform is purposely formed as a smooth walled tube closed at one end and without any thread or other cap attachment configuration about the mouth of the preform. The preform is moved to the bottle mold which completely forms the cap attachment configuration with the bottle in the blow-molding step. A processing dome is also formed from the preform in the blow-molding step to provide means to transfer the bottle to the trimmer which removes the dome. By using the smooth walled preform (without threads or any other cap fastening features), the bottle mold may utilize only a portion of the vertical height of the preform for the bottle. Bottle molds for a variety of bottle volumes and heights may employ the same preform and preform injection mold. The smooth walled preform also permits bottle molds with a variety of mouth diameters to be employed with the same preform injection mold.Type: GrantFiled: November 24, 1998Date of Patent: April 23, 2002Assignee: Brit CorporationInventor: Tony Salemi
