Casting Flexible Polyurethane Foam : 4 Steps (with Pictures ...
Expanding foam does just that, it expands, and it will try to push the mold pieces apart, or deform the mold if it is not rigid enough. It is common to use plaster of paris for the outer mold, and I have also successfully used thermoplastic in sheet form.

Direct injection expanded foam molding - Wikipedia
Direct injection expanded foam molding (also known as injection molded foam) is a manufacturing process that creates soft foam products direct from a compound into a final product. [1] This process eliminates the steps normally required for die-cutting and compression molding, because it manufactures the foam and the product, simultaneously.
Rigid & Flexible Foam Casting – brickintheyard
Flexible and rigid foams work best in silicone molds. Foams are measured by their expansion per cubic foot. A 2# foam for example, is 2 pounds per cubic foot once expanded and cured. This means that 1 pound of A mixed with 1 pound of B will yield a cubic foot of foam in free rise.
MOLD MAKING – EPS FOAM, EXPANDABLE URETHANE FOAM
By using EPS foam to create molds, you conserve material compared to directly cutting or machining the final parts from solid foam blocks. EPS foam molds only require the amount of material necessary to form the mold cavity, reducing material waste and cost.
