Title: Wilfred Houle: Innovator in Injection Mold Design
Introduction
Wilfred Houle is a notable inventor based in Largo, FL (US). He has made significant contributions to the field of injection molding, particularly in the design and method for in-mold coating of lenses. His innovative approach has led to advancements in the manufacturing process of coated lenses.
Latest Patents
Houle holds a patent for an injection mold design, which includes a method for in-mold coating of lenses and the production of coated lenses. This patent describes a method and apparatus for coating lenses within an injection molding machine that features a concave optical insert. The design includes a perimeter edge that meets the receiver ring in an annular contact region, forming a channel throughout this area. When molding a lens, a closed-loop coating containment lip is created by the channel. After the lens solidifies and the mold is opened, a predetermined volume of coating solution is applied, and the mold is re-clamped. This process ensures a uniformly thin layer of coating is cured onto the convex lens surface, effectively avoiding coating runoff and preventing mold contamination.
