4" x 8" x 1-1/2" HDPE Block Mold
High-density polyethylene (HDPE) is a polyethylene thermoplastic, used in the production of plastic bottles and cutting boards. HDPE is considered more durable and safer than PVC. We use HDPE to make an alternative to our blue silicone molds, and it is available in most standard single blank or block sizes, as well in custom order dimensions.
Our CNC machined design can be fully disassembled and prevents screws from stripping threads which commonly happens in home-made molds.
Cast Dimensions: 4" x 8" x 1-1/2" tall.
NOTE: Please confirm you have a large enough size pressure pot (5 gallon +) prior to ordering if pressure casting is your goal.
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.
