Initial Plastic Resin Pour

To begin the resin pour, I took the two parts of the mold and pressed them together then wrapped them in rubber bands to apply pressure onto them. The two part resin could be mixed 1:1 by volume or 90:100 by mass. for the first pour I opted to use the volume mix. I estimated I would need about 10 fl oz to fill the mold so I poured 5 oz of part A then 5 oz of part B into a mixing cup and mixed thoroughly. Then white dye was added in and again mixed thoroughly. The mixture was then poured into the mold in 5 parts. In between each part, the mold was tilted slightly and rotated to try and get the resin in all the overhang areas. Once poured, the 10 oz filled perfectly to the top of the mold. The mold was then placed in a pressure chamber and left to cure.

First Part

After the resin cured, the mold was taken out of the pressure chamber and rubber bands removed. The part was then pulled from the mold and the spout cut off. This part came out fairly good. There was however, a small amount of bubbling on the top of one of the overhangs. Other than that, the parting line was visible, but the rest of the part was very defined. The smooth parts was very smooth and the knurling was defined as well.
