PourReuseHatLRUnlike Permanent Hats, Marshall Gruber Reusable Hats can be used many times - thus eliminating the need and cost of a female mold - especially for molds that are not used extensively.

Fabricated of high-density polyethylene, a reusable hat will provide many trouble free castings if reasonable care is exercised in its use and storage. A reusable hat is applied to the mold after the initial pour of the matrix has been vibrated. It is placed over the bowl and the rim of the hat is gently pressed into the un-gelled matrix. A generous 2” flange is provided around the perimeter of the hat to allow for maximum adhesion of the hat to the matrix. Reusable hats are also available with an “untrimmed” flange around the perimeter.

Note: Reusable Hats are not as durable, nor as precise a fit as a high quality female mold, but offer the savings that a reusable female provides.
