Wood |
Inexpensive for small-batch production. |
Fair wearing properties. With care, will remain reasonably accurate over fairly long periods. Not suitable for high-volume production. |
|
Metal |
Excellent wearing properties. High standard of accuracy and stability. Suitable for high-volume production and shell molding. CAD/CAM improvements are greatly reducing cost and lead time requirements. |
Expensive. Difficult to modify. Equipment is less adaptable for movement from one foundry to another. |
