Getting ready to cast the aluminum version of the intake manifold
What the intake manifold should look like after all sensors and accessories have been installed.
The plastic model is placed into a steel cylinder in order to recieve the plaster that will be the mold.
Steve seals the bottom of the cylinder to a rubber base that will be removed after the plaster has dried. The purpose of the wax seal is to prevent plaster from leaking out the bottom.
The plaster has been mixed and poured. Now all we have to do is let it dry and then put it in the kiln. The purpose of firing it is to remove all the excess water from the plaster.
