Controlling The Curing Of A Rubber Compound

US Patent:
7433755, Oct 7, 2008
Filed:
Mar 30, 2007
Appl. No.:
11/694701
Inventors:
Richard Magill - Broomfield CO, US
John C. Van Doren - Bailey CO, US
Bruce Sellers - Golden CO, US
Tim Erickson - Littleton CO, US
Scott Schnieder - Aurora CO, US
Steve Courington - Lone Tree CO, US
Lance Bethel - Westminister CO, US
Assignee:
Signature Control Systems, Inc. - Denver CO
International Classification:
B29C 39/00, B29C 45/76, G05B 13/02, G06F 19/00
US Classification:
700198, 700 30, 700108, 700204, 264 401
Abstract:
A process for curing a natural or synthetic rubber compound under a plurality of curing conditions by: (1) obtaining time dependent data streams of dielectric or impedance values from a non-bridged impedance sensing circuit and a capacitor having the rubber compound being cured as a dialectric; (2) determining impedance related measurements from the obtained data streams; (3) determining a predictive curing equation by performing a multiple regression between: (a) reheometric data obtained from a plurality of different rubber compound samples cured in a rheometer at various environmental curing conditions, and (b) corresponding samples cured in a production mold at the same environmental conditions; (4) adjusting the curing equation to obtain cured parts having one or more desired properties; and (5) controlling the mass producing cured parts with a controller that uses the curing equation for predicting a cure time for each part, wherein the predictions are effective over variations in the rubber compound, and in the mold temperature.

Process And Apparatus For Improving And Controlling The Vulcanization Of Natural And Synthetic Rubber Compounds

US Patent:
2004001, Jan 15, 2004
Filed:
Oct 8, 2002
Appl. No.:
10/267197
Inventors:
John Doren - Bailey CO, US
Richard Magill - Broomfield CO, US
Bruce Sellers - Golden CO, US
Tim Erickson - Littleton CO, US
Scott Schnieder - Aurora CO, US
Steve Courington - Lone Tree CO, US
Lance Bethel - Westminster CO, US
Assignee:
Signature Control Systems - Denver CO
International Classification:
C08K003/34
US Classification:
524/445000, 524/493000, 525/331900, 525/329700
Abstract:
A process for curing a natural or synthetic rubber includes the measuring of curing conditions by dielectric or impedance means to produce a process curve (impedance property data versus time) followed by analyzing the process curve with a software algorithm which defines and statistically quantifies the correlation between the process curve and the desired part properties. The correlation relationship is applied in real time to end the curing process at the optimum time and to produce rubber parts of uniform quality and with reduced process cycle time.
