摘要： A method of forming an element to float at least partially on a surface of an at least partially liquid hydrocarbon mixture. The method includes mixing a polymer resin and a foaming agent together in preselected proportions to provide a material mixture, and heating the material mixture, to at least partially liquefy it. The material mixture is injected into a mold cavity configured to define the element's exterior surface in a series of at least three steps, commencing with an initial step. In each step, the material mixture is injected over a predetermined time period at a predetermined velocity and under a predetermined pressure. Each predetermined velocity in the steps following the initial step is less than the predetermined velocity in an immediately preceding step thereof. Each predetermined pressure in the steps following the initial step is less than the predetermined pressure in the immediately preceding step thereof.
