Casting flask 140 ml 5.5 cm ID, 6 cm high

Small casting flask.

I often need to cast small parts in Thermo-stable materials or resins.

This flask is a convenient way to hold 2 part silicone rubber to make the molds.

It should hold 140 ml when filled to the top, or 70ml when half filled.

Subtract the volume of your part from 140 ml (or 70) and you should come close to making the correct volume of two part silicone for the mold.

For casting:

1) Tape the hole in the botom. This hole is the "Blow out" hole for demolding.
