Thank you to everyone who joined us for our panel at Fantasy Basel! Here is a brief overview of what was covered and helpful links to aid you in your mold making endeavors!
Things to consider when deciding on a mold type:
- Shape of the item?
- Size of the item?
- What material will be cast in the mold?
- What is your budget for materials?
- What is your time frame?
- How many castings/ how long will you need the mold to last?
Common Mold Types
The item is placed in a container. Silicone is poured over the item forming a block that captures the details of one side of the item.
- Small items
- One sided item
- Groups of multiple small items
Two part pour on mold:
The item is placed in a container. Half of the item is sectioned off using clay. Silicone is poured over the exposed half, forming a block. The mold is then flipped over and the clay is removed. Silicone is poured in the second half capturing the detail of the other side.
- Two sided items
- Symmetrical /low profile items
Brush on mold:
Silicone is brushed onto the surface of the item. The silicone is built up in multiple layers. A plaster bandage mold jacket is added for support.
- Odd shaped items
- Vertical items
- Larger items
- Good for slush/roto casting items like masks
- Larger items like lifecasts
Unlike silicone, stone molds are not flexible. Layers of plaster and burlap are built up over the item. These molds can be made in single or multiple parts.
- Casting flexible items
- Baking foam latex appliances
- Slip casting latex/rubber
