Title: Norbert L. Bradley and Ceramic Injection Molding
Introduction
Norbert L. Bradley is an inventor associated with Sanford, Michigan. His patent work includes methods and apparatus for injection molding ceramic suspensions into greenware composites. Bradley is credited with 5 patents.
Latest Patents
Two of Bradley’s listed patents address injection molding ceramic greenware composites while preventing knit lines: “Apparatus for Injection Molding a Ceramic Greenware Composite Without Knit Lines” and “Method of Injection Molding Ceramic Greenware Composites Without Knit Lines.”
The disclosed process places an elastomeric bladder inside a mold cavity. Ceramic suspension is injected into the bladder, causing it to expand and press the suspension against the mold. This pressure helps prevent jetting and knit-line formation as the suspension fills the cavity. After molding, the greenware composite can be removed, dried, debindered, and densified to produce a finished ceramic part.
Career Highlights
Bradley’s listed professional association includes The Dow Chemical Company. His patent work reflects an interest in improving ceramic molding processes and the quality of molded components.
Collaborations
Ritchie A. Wessling and Virgil W. Coomer are identified among Bradley’s coworkers.
Conclusion
Norbert L. Bradley’s patents describe an elastomeric-bladder approach to ceramic injection molding designed to reduce defects and support the production of finished ceramic parts.
