There are many advantages when making a mold with liquid silicone. In this mold making tutorial, a decorative refrigerator magnet is used to make a single cavity mold which can be used to reproduce the design in many food and non-food mediums. A poured mold is square shouldered and sits level when in use. Once the basics are understood, you will find that this can be a very quick and efficient method for producing molds in quantity. Take advantage of this free resource and learn the basic principles of using a liquid silicone to create this professional looking and durable single cavity mold.

Step 2

Anchor-DitApply Anchor-Dit™ to the back side of the original and press it down into the center of the mold box.  Anchor-Dit™ should smoosh out the along the sides, insuring that a strong yet temporary bond has been established and that no silicone will creep underneath.  With the excess Anchor-Dit™ removed, the mold box is ready to receive the CopyFlex™ liquid.   CopyFlex Equal AmountsMix a small amount of CopyFlex™ liquid silicone rubber –  just enough to paint a thin coat over the object insuring that air bubbles are not trapped on the surface.

Step 4

CopyFlex mixtureScale out equal parts of A and B by weight, combine the two parts in a container and mix thoroughly until the color is uniform.  Make sure unmixed material does not remain on the sides or bottom.  

CopyFlex Skim CoatUsing a natural bristle artist brush, paint on a thin coat of CopyFlex™ onto the original. The idea here is not to cover the object but to imbed the mold making silicone into the details. We call this a “skim coat” and it insures that no air bubbles will be trapped in the nooks and crannies of the surface.

Step 6

CopyFlex pourOnce the skim coat is applied, a larger batch of CopyFlex™ silicone rubber is prepared and poured to fill the mold box at least 1/4″ above the highest point on the original.   CopyFlex Stretch PourCopyFlex™ should be poured in one spot from a height of about 12″ which allows the material to stretch as it falls.  We call this a “stretch pour” and it helps eliminate air that was incorporated into the liquid silicone during mixing.

Step 8

CopyFlex completed pourAllow CopyFlex™ to slowly creep over the original until it is covered completely.   Unmolding CopyFlexCopyFlex™ cures in about four hours.  A quick way to check if CopyFlex™ is completely cured is press a coin’s edge into the surface to see if it leaves an imprint. Cured CopyFlex™ will spring right back leaving no imprint whatsoever.
