Block Molds

Block casting molds are designed to pour a large cavity which allows a user to create casts that can be cut into multiple pen blanks from mixed color resins (dirty pour flip cup or swirls), embedding inorganic shredded materials such as US currency or color pencils, or organic materials such as coffee beans, pasta noodles, banksia pods, acorns, or pine cones. 

Blue molds except Gisi Style Molds cast Polyester Resin (Silmar 41), Urethane Resin (Alumilite Clear), and Epoxy Resin.

Mold release sprays help to extend the shelf life of our molds. We recommend Stoner Thermoset for Polyester and Epoxy Resins, and Stoner Urethane for Urethane Resin.

Please contact us or visit our Casting Basics Guide for more information on mold casting.
