Title: Innovations of Jeffrey M. Kingsbury
Introduction
Jeffrey M. Kingsbury is a notable inventor based in Santa Rosa, CA. He has made significant contributions to the field of optical lens manufacturing, holding a total of 2 patents. His work focuses on advanced molding techniques that enhance the production of ophthalmic lenses.
Latest Patents
Kingsbury's latest patents include a method of molding using gated dies. This innovative method and apparatus for molding and casting ophthalmic lenses involves a front surface die and a back surface die that are slidably and removably received in the bore of a molding or casting apparatus. Molding or casting compound is introduced between the two dies, which are then urged together to impress the die surfaces on the compound as it cures. The design includes at least one gate channel formed in the edge of the die, which serves to control the thickness of the molded part and manage excess material during the molding process.
Another significant patent by Kingsbury is related to the fabrication of thermoplastic optical components by injection/compression. This method involves a series of sleeves and mold inserts that create a mold cavity for the optical lenses. The assembly is heated above the glass transition temperature of the thermoplastic, allowing for precise molding. After the injection of the thermoplastic, the mold inserts are compressed, and excess material is expelled, ensuring high-quality lens production.
