Composites Molds/Tools

Composite parts are typically formed in molds, also known as tools (see CompositesWorld’s introduction to fabrication methods for a primer on manufacturing methods). Tools can be made from virtually any material. For parts that will be produced in low quantities and can be cured at ambient or low temperature, or for prototype parts, where tight control of dimensional accuracy isn’t of prime importance, materials such as fiberglass, high-density foams, machinable epoxy boards or even clay or wood/plaster molds often are suitable.
