The Original and still the best Maneater Crafts HDPE Moulds.
These moulds are semi-permanent in nature, they won't warp or crack but will take lots of abuse, unlike traditional silicone molds. These tough moulds are solid bodies, milled from blocks of High Density Polyethylene.
Demoulding 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.
A release agent must be used due to the rigidity of the molds. Just spray the release agent into and on top of the chambers ensuring complete coverage and allow to dry before pouring your resin.
Apply a release agent to 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 ployester resin blanks will release with little effort at all. Epoxy blanks may require a few extra raps against your bench top before releasing.
