http://www.artmolds.com. Call Now to order 908-273-5401 Vacuum de-airing is the method used when applying a vacuum to viscous material to remove the air trapped in the mixture. Air bubbles are the bane of all mold makers as they weaken mold making and casting materials. In transparent acrylics and resin it is imperative to remove all air bubbles as they are unsightly and will diminish the quality of the finished product. EnvironMolds offers the inexpensive yet sturdy DIY vacuum chamber to assure a bubble-free mold making when mixing resins such as and polyurethanes and silicone rubbers and slower setting harder resins. The DIY vacuum chamber must accommodate a larger mixing container as in the deairing process the liquid contents will expand three times its volume, so if the vacuum
chamber is too small one will have to mix many small batches to accommodate this phenomenon. The vacuum chamber is needed for de-airing (eliminating air bubbles) for materials prior to their setting. The process is fairly straight forward. The casting or molding material is mixed according to the manufacturer’s directions. The mixing containing is filled one third of the way and then placed into the ArtMolds DIY Vacuum Chamber which accommodates a 2 1/2 gallon mixing container.
The vacuum pump is turned on and the air is removed. Once the vacuum gauge shows the maximum vacuum the liquid will begin to foam and rise in the bucket until it reaches the rim. It will continue to froth until it finally collapses. The vacuum is maintained for another minute or so when the mixture then has been completely de-aired
Artist and author Dave Parvin wrote that I recently found out that ArtMolds claims to have a functioning cheap vacuum chamber for less money one would spend to construct his/her own, I just had to try it. To really put it to the test, I decided to let one of my studio assistants, Stevie, do the assembly. The first step Stevie had removed the contents of the box which consisted of:
1. Vacuum chamber body
2. Two rubber gaskets
3. Two acrylic plastic lids
4. A vacuum gauge
5. An exhaust valve body assembly
6. A yard of plastic tubing
The only two things required for assembly of this DIYvacuum chamber to eliminate air bubbles, which are not supplied are an adjustable wrench and a dab of petroleum jelly. I substituted 13 mm and 14 mm open end wrenches which worked perfectly. Pliers would have sufficed as well. Stevie had no problem following each of the nine simple assembly steps with no guidance from me except for the last one which I will explain.
In the next step Stevie removed the protective paper from the acrylic lids. The directions said to remove the paper from both sides of both lids
Next, one of the two rubber gaskets was centered on the bottom lid. Stevie then placed the vacuum chamber in the center of the bottom gasket, making sure that the entire perimeter of the chamber was sitting evenly on the gasket.To operate, connect the plastic tube to your vacuum source. You are ready to use the vacuum chamber. Anyone with any experience with pneumatics will know how to do this. However, since Stevie had no exposure to air driven equipment, I had to help her with this step. I showed her three different ways of doing this. In the first, I had her attach the plastic line directly to the vacuum pump with another barbed connector.. The advantage to this method is that it is the simplest
and will result in the least amount of loss of vacuum due to leakage. The main disadvantage is that the vacuum source has to be close to the pressure chamber.
Note that the ArtMolds DIY vacuum chamber is large enough to contain a 2 1/2 gallon bucket. A bucket of that size is sufficient to hold a gallon of liquid and allow for expansion when evacuated. I have probably been using vacuums chamber for deairing for at least twenty years in my studio and do not ever recall a need to
evacuate more than a gallon of liquid at one time. So as we know, while size does matter, this ArtMolds DIY vacuum chamber should be large enough for just about any purpose a sculptor might have. At higher altitudes, one cannot pull the same 29 plus inches of mercury that one can achieve at sea level. The 25 inches that one should be able to get in Denver is still sufficient. However, for thicker liquids it may be necessary to rock the chamber back and forth to help bring the bubbles to the surface and allowing the gases can escape. It is important that the chamber be light enough that it can be picked up for this purpose. The edges on the acrylic lid make perfectly good handles. Don’t worry about the lid coming off; if you are strong enough to pull the lid loose from the chamber with an established vacuum, I suspect the US Olympic Committee would like to talk to you.
