ArtMolds Vacuum Chamber

Click here to zoom

ArtMolds Vacuum Chamber To assure a bubble-free mold when mixing rubbers and silicones a vacuum chamber is required. The ArtMolds' Vacuum Chamber is designed for deairing (eliminating air bubbles) in rubbers. This PVC chamber, along with ½-inch Lexan plates make a safe and efficient unit. The vacuum chamber comes with all fittings, exhaust valve, vacuum gauge, rubber gaskets, and top and bottom ½-inch clear Lexan plates. All you need is a vacuum pump that will pull 29.9-inches of mercury (Hg) at sea level, needed to deair your materials. As a satisfactory and best value vacuum pump we recommend the economical Robinair vacuum pump 6 CFM or higher, to use with your ArtMolds' Vacuum Chamber. Specifications: Capacity: 4-gallons (approximately) Dimensions: 10-inch diameter by 10-inch tall Maximum Pull: 29.9-inches of mercury (Hg) at sea level 24.87 hg at elevation of Denver, CO Weight: 20-pounds / Shipping weight 22-pounds Vacuuming Process: Mix your rubber according to the manufacturers directions. The mixing container must hold at least four times the amount of material you are vacuuming to allow for the expansion of the material. Once your vacuum reaches 29.9-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 to vacuum for another 2-3-minutes to make certain all of the air has been removed from your material. Release your vacuum, remove your material from the 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.
Assembly Instructions: Thread your gauge onto the brass fitting that will attach to the vacuum chamber Thread your gauge onto the brass fitting that will attach to the vacuum chamber Take the assembled fitting with gauge and thread it into the side of the chamber Place the Lexan plates on flat surface Place one of the red gaskets in the center of the Lexan plates Place the PVC cylinder/Vacuum Chamber evenly in the center of the gasket The second red gasket is placed on the top chamber The second Lexan plate will be placed over that gasket to seal your Vacuum Chamber Connect the tube to your vacuum source Download Owner's Manual Here Download Assembly Instructions
CAUTION: PLEASE TAKE SAFETY PRECAUTIONS WHEN USING YOUR VACUUM CHAMBER. Always wear safety glasses, no close or prolonged viewing through Lexan plate. Never use the Lexan plate as a cutting surface.
