Vacuum Chamber. Take the next step in studio equipment by adding that important vacuum chamber. To assure bubble-free mold rubber when mixing polyurethane and silicones, a vacuum chamber is required. The low cost ArtMolds' Vacuum Chamber is the perfect addition to the small studio, school, university or protype lab. The ArtMolds' Vacuum Chamber has been engineered  for deairing (eliminating air bubbles) mold making and casting rubbers. Though the price point of our vacuum chamber may be low, its design does not skip on prefessional grade quality -- and safety.

This PVC vacuum chamber, along with ½-inch opitically clear acrylic plates make a safe and efficient unit. The vacuum chamber includes all machined brass fittings, including a  pet cock exhaust valve, hose barb to connect your vacuum pump, a vacuum gauge, a pair of matched rubber gaskets, and a set of ½-inch clear acrylic plates. All you need is a vacuum pump for your new vacuum chamber that will pull 29-inches of mercury (Hg) at sea level, needed to deair your materials.

Vacuuming Process:

Mix your rubber according to the manufacturers directions. Use a container that holds at least four times the amount of material you are vacuuming to allow for the expansion of the material. Once your vacuum chamber reaches 29-inches of mercury (at sea level), the material will begin to rise (resembling foam) for a minute or two. When the material falls it will plateau and not rise any more. You will want to continue opertaing the vacuum chamber for another 2-3-minutes to make certain all of the air has been removed from your material. Open the petcock of your vacuum chamber to allow air inside, remove your material from the vacuum chamber. Pour the material slowly starting from the corner of the mold box, or mold, letting the material to flow freely into the box or mold cavity. This method will usually not introduce any new bubbles into the vacuumed material. To insure that the material is totally devoid of air bubbles you can place the entire mold/mold box into the chamber for an additional few minutes. This will assist the material into difficult areas of the mold/mold box.
