With a total of 8 patents to his name, Cerny has made strides in enhancing manufacturing processes, particularly in the production of plastic closures.

Latest Patents

One of Cerny's latest patents is an "Apparatus for molding a plastic closure with air-assisted ejection." This innovative apparatus features a male mold assembly that includes a forming pin and an outer pin sleeve, which work in conjunction with a female mold to define a mold cavity. To facilitate the mechanical stripping of a molded closure from the forming pin, pressurized air is introduced into the molded closure through at least one air passageway that extends axially between the forming pin and pin sleeve. This method allows for the outward expansion and formation of the plastic closure during ejection, significantly reducing the forces exerted on the closure. Consequently, this innovation minimizes the cooling time required during the molding cycle prior to ejection, enabling significantly increased operating speeds for the compression molding apparatus.
