A closed-loop method of heating a preform for a blow molding operation is provided. The method involves inspecting a preform upon entry into a system, heating the preform, measuring a preform temperature along its longitudinal axis and around its circumference, heating the preform again, measuring a preform temperature again along its longitudinal axis and around its circumference, comparing the second temperature measurement to a known, acceptable temperature measurement, and optimizing the heating step(s) to ensure subsequent optimization of the heating of subsequent preforms.

A medical stent mold includes a tube having an interior passage sized and dimensioned to receive a stent assembly disposed at least partially about a central portion of a stent balloon. The medical stent mold may also include a housing forming a chamber through which the tube extends. The tube may include a thermally conductive material and may have a body portion that extends within the chamber and an end portion that is proximate the body portion and that extends away from the housing. Forced convection may be used to quickly heat and cool the tube. Methods of increasing retention of an expandable stent assembly on a stent balloon and of detecting a leak in a stent balloon are also included.

An inspection and ejector unit for preforms for plastic containers in a transportation line, has at least one driver device which picks up preforms travelling from an inward conveyor device to the inspection and ejector unit, transports them further and passes on at least some of the preforms to an outward conveyor device, at least one detection device by which faulty preforms in the driver device are detected, and at least one ejection device by which preforms which are detected as faulty are removed from the driver device, and a corresponding method.

A vulcanizing mold includes an upper mold and a lower mold. At least the lower mold is provided with a cavity in which unvulcanized sample rubber is charged, heated, and subjected to press vulcanization, so as to be formed into a rubber specimen for blowing limit observation continuously changing in vulcanization degree in a longitudinal direction. The cavity is provided with a first cavity that changes in depth in the longitudinal direction and is for producing the rubber specimen, and additionally provided with a second cavity that connectedly extends from the first cavity and is a space in which a temperature sensor is disposed to plot a temperature rise curve of the sample rubber during the vulcanization.
