Pressure Pot

A pressure pot is required for bubble-free and air-trap-free resin castings. This is especially critical in creating clear resin castings as trapped air can mar the appearance of a crystal clear casting. The ArtMolds Pressure Pot is designed for use in applying pressure to force air out of resin and to force resin into thin sections of a mold. This eliminates air bubbles and air traps in the cured castings. This pressure pot includes a gauge and all the other fittings. However, you will also need to purchase an air compressor of at least 3.5 H.P. and a ¼-inch adapter/coupling to attach the air compressor to the pot. Both items are readily available at the larger home supply centers such as Sears, Home Depot and Lowes.

Pressure Pot Specifications: Capacity: 2.1/4 gallons Dimensions: 8 ¾-inch diameter by 11.5-inches tall Maximum Pressure: 50 PSI Weight: 20-pounds Gasket Material: Polysulfide

Casting under pressure is the best way to make high quality resin castings. This is especially true with difficult recesses and complex molds. Pressure casting compress air to sizes undetected by the human, creating a virtually bubbleless casting.
Simply cast your part in your mold and then insert your mold into the pressure pot. Secure the lid tightly, and then turn on your air supply to fill the pot to 40-50 PSI. (DO NOT EXCEED 50 PSI). Leave the pressure pot on until the casting has cured. Then remove the air source and release the air from the pot. Unfasten the lid and remove your mold from the pot. Demold your void free casting.
Note: You will want to make certain you do not pressure cast soft rubbers as the air bubbles will return once exposed to normal air prussure. You must use your vacuum chamber to remove all air from the mold rubber to avoid having the mold collapse in areas of your mold that have air trapped under the surface. You will have the appearance of warts on the surface of the finished result if you do not.
Summary: Mix your material in accordance with the directions and pour it into your mold. Place the mold into the pressure pot. Place the lid on the pressure pot and locate the (4) locking slots on the cover lining them up with the (4) swing up bolts on the tank. Place the (4) swing bolts into the slots in the cover and secure the (4) hand nuts tightly on the cover. Make certain the nuts are secured tightly before pressurizing the tank.
 Assembly Instructions: Attach the air supply hose (not included) to the ¼ NPT air inlet connector (not included) of regulator.
