Various systems and apparatuses for heating molds, including for example tire molds, are disclosed. Heating of molds may be effected via induction heating technology. In one embodiment, a system for heating a tire mold is provided, the system comprising: a tire mold formed from a mold material having a base material relative permeability, wherein the tire mold includes a mold surface for contacting a tire, the mold surface for contacting a tire having a mold surface for contacting a tire relative permeability, wherein the tire mold includes a mold back oriented substantially opposite the mold surface for contacting a tire, and wherein the mold surface for contacting a tire relative permeability is greater than the base material relative permeability.

A tire vulcanizing device includes a vulcanization mould and a central part. The vulcanizing mould includes moulding parts that defining a curing chamber therebetween. Inside the curing chamber is arranged a heating and ventilation apparatus structured for use with a heat-transfer fluid. The central part is structured to collaborate with the vulcanization mould by providing support to a heat-transfer fluid inlet and establishing communication between the heat-transfer fluid inlet and the curing chamber. The central part includes heating elements that are configured to be brought into operation before the heating and ventilation apparatus is brought into operation to cure a tire using the heat-transfer fluid.

The disclosure relates to a molding element including a main lamella and two ribs positioned on either side of the main lamella at a certain distance from this main lamella. The ribs are mold-able to grooves in the tread, these ribs including rounded ends. The main lamella includes a cutting edge, the cutting edge making an acute angle. The ribs are curved in their length with a curvature C and in that the lamella is curved with the same curvature C.

Systems for depositing coatings onto surfaces of molds and other articles are generally provided. In some embodiments, a system is adapted and arranged to cause gaseous species to flow parallel to a filament array. In some embodiments, a system comprises one or more mold supports that are translatable.

The invention is a cleaning method for the production of vehicle tire full-molds having profile. The method as the subject of the invention comprising the process steps respectively, the contaminated full-mold (1) is taken a pre-treatment with an ultrasonic cleaning apparatus (10), depurated full-mold (2) is re-cleaned by putting to dry ice process in a first cleaning station (20), cleaning of the full-mold with preferably multiple number of ultrasonic devices (51, 52, 53) by immersing into a cleaning liquid (50) in a second cleaning station (40), rinsing by taken in to a rinsing station (60), putting to another process by taken in to a passivation station (70), and drying by taken in to a drying station (80).

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.

Invention is a cleaning machine for tire curing sidewall (80) that comprises a basket (10), a rotational base (20) which mounted into thereof, a nozzle (60) provided in a movable manner on the rotational base (20), of extending towards the open side of the basket (10) and having an intake (63) connected to inlet (62) in a fluid transferrable manner. The cleaning machine comprises a rotating joint (40) which mounted radially to the outward direction on the rotational base (20) and a telescopic arm (50) which carrying the nozzle (60) at the free end thereof and which of fastened on a rotational base (20) with the rotating joint (40).

Provided are a vulcanization device for a pneumatic tire and a method for vulcanizing a pneumatic tire. A pressurizing medium having a relatively low pressure is supplied through a pressurizing medium low-pressurization/supply line into a vulcanization bladder having a tube-like shape inserted into a green tire in a vulcanization mold to inflate the vulcanization bladder. Thereafter, a heating medium is supplied through a heating medium supply line into the vulcanization bladder (2). Then, a pressurizing medium having a relatively high pressure is supplied through a pressurizing medium supply line into the vulcanization bladder to increase internal pressure of the vulcanization bladder while the media in the vulcanization bladder are circulated through a circulation line extending outside the vulcanization bladder, thereby vulcanizing the green tire.

Tire mold maintenance and repair systems and related methods are disclosed. According to an aspect, a mold maintenance and repair system includes a mold holder. The mold holder is configured to releasably attach to a support structure and to hold a mold. The mold comprises contoured upper portion for molding an item and an attachment lower portion for attaching to the mold holder.

A method is provided for forming an impermeable barrier layer on an inner tire surface of a tire. An assembly is also provided along with a kit for forming an impermeable barrier layer on an inner tire surface of a tire accordingly.
