Tapered Round Locks Are usually used as locators only. As with tapered bar locks, they do not provide early alignment or protection of cores,

and thermal expansion must also be considered because of the 360-degree contact area. Tapered round locks are usually not recommended for mold bases with a large distance between locators. Tapered round locks are recommended for use in mold inserts when the distance between locaters is small, minimizing thermal expansion.
