.... This is particularly true when machine molding or coremaking methods are employed. Metal patterns and coreboxes that are machined to size often will provide closer tolerances than will cast-to-size metal or wooden patterns. High-strength cast components frequently demand tight dimensional tolerances or thin-wall...
