With a total of 4 patents to his name, he has developed innovative methods and devices that enhance the efficiency and effectiveness of material layering and molding processes.

Latest Patents

One of Yi Fan's latest patents focuses on devices and methods for forming segregated layers from mixtures of granular materials. This invention allows for the layering of initially mixed granular dissimilar material components deposited by surface flow. The process is achieved by varying the relative angle of the flowing layer periodically with respect to the bulk of the pile formed. The thickness and extent of the layers can be controlled by adjusting the timing and extent of the surface variations. Additionally, variations in surface flow rates can be realized through several methods, including altering the feed rate from an inlet to a collection base, changing the feed location, tilting the collection base, and reducing the pile repose angle using vibration or fluid flow.

Another significant patent involves a process for forming a rotational molded article. This process includes providing a blend of powders, including a polyolefin and a dispersant, and rotational molding the blend to create a molded article. The specific parameters of the powders, such as density and melt index, are carefully controlled to achieve the desired properties in the final product.
