The 20x16x3" formed polyethylene mold is a perfect size for larger epoxy resin and wood serving boards, charcuterie boards and small table tops. If you are looking for a slightly smaller mold we highly recommend cutting pieces of 1.5" thick HPDE plastic (or screwing two or three 3/4" pieces together) to create a spacer to create a void that resin will not fill in.

Like our popular line of silicone molds, the formed polyethylene molds are created just for makers, resin artists and wood workers. These time saving, one piece, completely sealed, durable HDPE molds significantly cut down on the setup and demolding time usually involved with other molds and forms. These molds are superior to wood and tuck tape, and multiple piece (screwed together) HDPE molds because:

  • They never need to be assembled, or disassembled. Saving huge amounts of time.
  • Like most HDPE molds, epoxy resin does not stick to the surface of the mold. 
  • The strength and flexibility of the molds allows you to insert and remove pieces of wood easily.
  • The corners and edges never need to be sealed.
  • The side walls are made of 1/8" to 3/16" thick high density polyethylene. This allows them to be more flexible than thick HDPE molds, which is a benefit when it comes to demolding. Plus, the sides are at a ~90 degree angle*, not tapered outward like the welded HDPE molds on the market, leading to less wasted resin and less finishing work. Due to the thickness and internal stresses of HDPE plastic, side walls are often imperfect.
  • The molds are reusable, and we have yet to seen a "worn out" polyethylene plastic mold yet. 
  • To remove the set and dry epoxy piece from the mold, simply push on the inside of the upper side walls of the mold with your hands (or use a rubber mallet) to detach the walls of the mold from your piece. Then turn the mold upside down and gently hit the bottom side with a rubber mallet until the piece falls out onto your work surface.
  • To make demolding even easier, we recommend using a mold release spray, available on Amazon. This is definitely NOT REQUIRED but will reduce the efforts required to demold your work from these molds.
  • *Note: These molds are best suited to resin and wood applications, as your piece will require trimming of the perimeter to ensure perfect 90 degree straight edges and flat bottom, as well as planing after removal from the mold (due to the radiused edges and corners, and not-perfectly flat bottom of the mold). Unlike our silicone molds, the sidewalls are often imperfect and require trimming during the finishing stage. If you are a resin artist using resin only and want to be able to do as little finishing as possible to your piece, we recommend our line of silicone molds over our polyethylene molds.
