Patent number: 8153235Abstract: An injection molded foam article including a structure and a projection projecting from the structure. The thickness of the projection is greater than 40% of the thickness of the structure and the front surface of the structure opposite the projection is free of sink marks.Type: GrantFiled: November 24, 2010Date of Patent: April 10, 2012Assignee: Hendrickson USA, L.L.C.Inventors: Jeffrey Russell Zawacki, Wilfried Mozer, Brian Leonard Desmith

Patent number: 8128394Abstract: Tooling assemblies for interfacing with interchangeable molds are provided, each with a tooling body for mounting to a platen of a press of an injection molding machine and for receiving an interchangeable mold block. Interchangeable mold blocks are also provided for forming articles. A series of fasteners fasten each mold block to one of the tooling bodies. Alignment systems are oriented within a perimeter of the mold block to permit expansion of the mold block relative to the tooling body to accommodate varying rates of thermal expansion of the tooling body and the mold block. Methods for assembling a mold, molding an article and interchanging a mold with interchangeable mold blocks are also provided.Type: GrantFiled: March 26, 2009Date of Patent: March 6, 2012Assignee: Delta Engineered PlasticsInventors: Brian L. Desmith, Wilfried Mozer, Jeffrey R. Zawacki

Patent number: 8062451Abstract: A method of laminating a decorative layer to a molded part comprises molding a part formed of an amorphous or semi-crystalline thermoplastic resin and applying a segment of co-extruded an amorphous or semi-crystalline thermoplastic resin film to the part. The part is loaded into a vacuum forming nest and maintained in a heated state. The film is heated and then positioned over the part in a pressure box. A vacuum is applied through the vacuum forming nest to a first side of the film facing the part at the same time air pressure is applied through the pressure box to a second side of the film. The film is bonded directly to the part without the need for an adhesive.Type: GrantFiled: February 23, 2009Date of Patent: November 22, 2011Assignee: Delta Engineered PlasticsInventors: Wilfried Mozer, Brian L.

Patent number: 8048347Abstract: The method of manufacturing an article having a surface, a skin, and a core includes closing a first mold portion on a compressible seal. The seal is disposed between the first and second mold portions. The portions define a pressurizable mold cavity having a spaced apart injection port and a vent. The mold cavity is pressurized at a first pressure greater than atmospheric pressure. Molten plastic and blowing agent are injected form gas cells within the mixture. The gas cells have an internal pressure exceeding the first pressure. After waiting for a first period, the pressurizing gas is vented for a second period at a rate sufficient to rupture the gas cells which form a skin adjacent to the mold cavity wall. The skin defines a core cavity filled with the foamed mixture, which is solidified. The mold portions are separated releasing the article.Type: GrantFiled: March 26, 2009Date of Patent: November 1, 2011Assignee: Delta Engineered PlasticsInventors: Wilfried Mozer, Brian L. Desmith
