This is a small mold Box and mold Cylinder for making RTV (room Temperature Vulcanization) Silicone rubber molds of small gears and objects. Also included is a Flask and Sprue base for lost wax casting of small parts.
Place an object on the base of the box or cylinder. Small undercuts are ok if your using flexible silicone rubber two part mixes. Mix the silicone rubber and pour it over the part at the base of the box or cylinder. When you remove the silicone rubber form the box or cylinder mold it can then be used as a casting mold for the small part.
The base of the box and cylinder is about 35mm.
The walls are canted out to make it easier to take the mold out of the casting box.
Design time 7 minutes.
Working with primitives only.
Time from inception to final publishing 13 minutes.
