Abstract: A Silicon based expandable curing bladder comprising, an expandable tire curing bladder (20) composition comprising a silicone base at least 50 to 99 percent by weight of the composition. The curing bladder (20) comprising a silicon base and/or additives which are selected from the groups consisting of silicon base rubber, silicon base compound, silicone color, platinum catalyst, inhibitor, activator, heat stabilizers, crosslinkers and filler in order to increase release properties of an expandable curing bladder with long durability. A production method which is preferably compression and/or transfer molding or injection molding is also described accordingly.

Abstract: Invention is a cleaning robot for cleaning the inner surfaces (5) of the half mold (4) of tire curing molds comprising a basket (10) wherein a lifting arm (50) placed in a manner pivotal on a proximal end (52), the lifting arm (50) pivoted on a distal end (54) of a support arm (70). The cleaning robot fits completely into the basket (10) when the positioned as close and comprising a movable head (80) having a nozzle (82) coupled in a manner to establish fluid communication to the dry ice inlet (84) and located at the distal end (76) of the support arm (70) and a free end which is configured movably closer to the inner surface (5) such as at a vicinity of the inner surface (5) along the contour of its when the positioned as open.
