Latest Patents

Tzong-Ming Yeh holds a patent for a "Process for molding plastic lenses." This invention describes an improved injection/compression molding process for manufacturing high-quality concave optical lenses of thin thickness. The process involves injecting a thermoplastic material into a mold cavity designed with adjustable thickness. Initially set at a greater thickness than the lens to be produced, the cavity gradually reduces in thickness through a compressional force applied to the thermoplastic material. This method not only addresses common issues such as weld lines and birefringence but also enhances quality control, eliminates the need for external heating or cooling, increases production rates, and reduces costs.
