Vacuuming Process Using the DIY Vacuum Chamber Kit:

   
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. Order now click this link for the DIY vacuum chamber.
