Tooling boards are used in a variety of industries such as motorsport, aerospace and foundry. They are mainly used to form prototype models or moulded them into desired shapes. A range of familiar products use tooling boards, and manufacturers rely on them in a wide range of commercial setups as well as in day-to-day life.
They are made from filled polymer materials which are then bonded together to form more useful larger blocks. Tooling board can be shaped by hand, but the usual chosen method is CNC machining.
There are two different well-known types of tooling boards, polyurethane and epoxy board which have different properties.
The Types of Tooling Board
Polyurethane tooling boards are sold at a lower cost than epoxy due to them not being able to be heated to as high of a temperature to shape. This makes them the ideal choice for prototype model work as they are very lightweight and versatile, often seen on film sets to set up as props.
Epoxy Tooling Boards withstand high-temperature applications (up to 230 degrees), so are used when the material needs to be put under intense stress to be shaped. It has high dimensional stability and therefore works well when highly accurate and complex moulds are required.
