Method And Apparatus For Producing Multilayer Plastic Articles

View page
US Patent:
53804791, Jan 10, 1995
Filed:
Nov 9, 1992
Appl. No.:
7/973962
Inventors:
Walter J. Schrenk - Midland MI
Herbert C. Roehrs - Beaverton MI
Ranganath K. Shastri - Midland MI
Ralph E. Ayres - Midland MI
Mark A. Barger - Midland MI
Jeffrey N. Bremmer - Midland MI
Assignee:
The Dow Chemical Company - Midland MI
International Classification:
B29C 4516
US Classification:
264241
Abstract:
Methods and apparatus are provided for making multilayer plastic articles. Initially, two or more streams diverse thermoplastic materials are provided. Layers are foraged from these streams and are arranged in a layered first composite stream. The first composite stream may be directly formed into a desired configuration by a molding process or may be manipulated to form a second composite stream having an increased number of layers before being formed into the desired configuration. The resulting articles are comprised of a number of discrete and substantially continuous layers.

Methods And Apparatus For Generating Interfacial Surfaces

View page
US Patent:
50947931, Mar 10, 1992
Filed:
Dec 21, 1990
Appl. No.:
7/632448
Inventors:
Walter J. Schrenk - Midland MI
Ranganath K. Shastri - Midland MI
Ralph E. Ayres - Midland MI
Daniel J. Gosen - Saginaw MI
Assignee:
The Dow Chemical Company - Midland MI
International Classification:
B29C 4706
US Classification:
264171
Abstract:
Method and apparatus for generating interfacial surfaces in a fluid mass which: (a) divide a first stream of the fluid mass into a plurality of branch streams, redirect or reposition the branch streams, expand and contract the branch streams in a symmetrical fashion, and recombine the branch streams to form a second stream of the fluid mass; or (b) divide a first stream of the fluid mass into a plurality of branch streams, redirect or reposition the branch streams, recombine the branch streams to form a second stream of the fluid mass, and expand and contract the second stream in a symmetrical fashion.

Method For Producing Injection Molded Multilayer Articles

View page
US Patent:
52020746, Apr 13, 1993
Filed:
Apr 11, 1991
Appl. No.:
7/684467
Inventors:
Walter J. Schrenk - Midland MI
Ranganath K. Shastri - Midland MI
Herbert C. Roehrs - Beaverton MI
Ralph E. Ayres - Midland MI
Assignee:
The Dow Chemical Company - Midland MI
International Classification:
B29C 4516
US Classification:
264241
Abstract:
A method of making a multilayer plastic article by forming a multilayer stream of diverse thermoplastic materials and injection molding the multilayer stream directly into the article. The multilayer stream can be formed by coextrusion of the materials or by coextrusion followed by layer multiplication in one or more interfacial surface generators/static mixers. The coextruded stream, or a multiplied stream from the one or more ISG's, can also be divided into substreams and the substreams thereafter recombined prior to being injection molded so that the layers in one such substream are angularly oriented with respect to the layers in another substream.

Method For Producing Blow Molded Multilayer Plastic Articles

View page
US Patent:
55408788, Jul 30, 1996
Filed:
Sep 27, 1994
Appl. No.:
8/313669
Inventors:
Walter J. Schrenk - Midland MI
Ranganath K. Shastri - Midland MI
Herbert C. Roehrs - Beaverton MI
Ralph E. Ayres - Midland MI
Assignee:
The Dow Chemical Company - Midland MI
International Classification:
B29C 4922
US Classification:
264513
Abstract:
A blow molded multilayer plastic article having a large number of layers is formed. First and second diverse thermoplastic streams are extruded into a coextrusion feedblock. In the feedblock the streams are divided into multiple streams and arranged into a first composite stream having a substantially uniform distribution of the layers. The first stream is fed into an interfacial surface generator in which the stream is manipulated to form a second composite stream having even more layers of substantially uniform thickness. This second stream is then formed into a preform such as by injection molding and this preform is blow molded. The second composite stream and preform are formed so that the layers of first and second materials lie generally parallel to a critical surface and possess substantial uniformity when blow molded.
