Abstract: A method of making a carburetor float by first creating a homogeneous mixture of gas and polymer in a plastic injection machine. The gas/polymer mixture is injected into a tool having a mold cavity. A moveable portion of the mold cavity allows the gas/polymer mixture to expand in that area thus forming a foamed portion of the finished float. The portion of the mold that is stationary does not allow the gas/polymer mixture to foam and thus forms a portion of the finished float with a higher density that the foamed portion. The result is a float made of the homogeneous mixture with two differing densities in two different portion of the float.
