The strip thread mold design is not robust enough to provide a leak proof result. There are Primarily Two Types of Unscrewing Molds: The first type is known as a reciprocating core. This type does not require the stripper action to take part in unscrewing. This type of unscrewing mold requires racks, gears and hydraulic cylinders.

Unscrewing-core tooling with hydraulics uses a rack (a linear, toothed rail) that is usually mounted atop the mold. The toothed grooves of the rack enter the mold through the top and intersect with spur-type gears inside, which turn the core. A hydraulic cylinder moves the rack to turn the core.
