Introducing a brand new line of custom crafted molds that are sure to change the hand casting industry. These are semi-permanent in nature. They won't warp or crack but will take lots of abuse, unlike traditional silicone molds. These tough molds are solid bodies, milled from blocks of HDPE (High Density Polyethylene). And best of all, they stack!! There is no need for a casting rack! Demolding is easy! Just pull the suction plugs, turn the mold upside down, rap the ends a few times on your work bench and watch the blanks fall out. These true beasts are designed to DEVOUR THE COMPETITION!
This mold system has overall dimensions of 7.25" x 6.75" x 1.60" with four casting chambers, each measuring 5.25" x .84375" x 1.0". The blanks can easily be end trimmed and squared up on a table saw, if so desired.
Includes eight large stopper silicone inserts and eight small stopper silicone inserts! The small stoppers will accommodate tubes 7mm - 27/64" in diameter. The large stoppers will accommodate tubes 27/64" - 13.2mm.
A release agent must be used due to the rigidity of the molds. Maneater Wax Mold Release is highly recommended. Just brush the release agent into the chambers and on the silicone inserts, ensuring complete coverage. Allow to dry before pouring your resin. Also apply a release agent on the rubber plugs to keep them free of any resin buildup caused by potential spillage.
A rubberized dead blow hammer will help the demold process greatly. Lightly rap the bottom and sides of the mold once your blanks have fully cured, then turn the mold over and lightly rap the mold ends against your work bench top to see your blanks release. Based on personal experience, Alumilite and polyester resin blanks will release with little effort at all. Epoxy blanks may require a few extra raps or a blast of air from a rubberized nozzle before releasing.
