Latest Patents
One of Sean Weir's latest patents is a non-return valve designed for use in a molding system. This invention relates to a non-return valve that can be configured for use anywhere along a molding material flow path. The valve includes an improved means to restrict the backflow of melt during injection. A spigot-seal is configurable between overlapping, closely-spaced, and mutually parallel complementary male and female spigot portions. This design maintains effective backflow restriction even during transient movement between the spigot portions. The non-return valve is particularly advantageous when used in a barrel assembly of an injection unit for the injection molding of a metal alloy.
Another significant patent by Weir is a brake for a molding machine valve. This device features a valve structure that includes an outlet body designed to define an outlet. The outlet body attaches to a melt processing screw of a molding machine. The valve structure also includes an outlet cover that can selectively close and open the outlet. A brake is integrated to decelerate the outlet cover in response to the deceleration of the outlet body, ensuring that the outlet remains substantially closed.
