Methods are provided to remove vulcanized rubber contamination and other process related residues, such as sulfur-based residues from a vulcanization mold. A vulcanization mold can be placed in a reactor where solid vulcanized rubber contamination can be turned into its base substances on a particle level by reversing the vulcanization and breaking the sulfur-bonds of the contamination. The reactor can be filled with a process liquid that interacts with the devulcanized particles. Energy can be applied to the process liquid to set it into motion to transport devulcanized particles away from the mold surface and from mold cavities such as air venting systems, of which can include then a combination of devulcanization and then a nucleation process to remove the contaminants from the mold.

A liquid-jet-guided laser system can be used to generate functional slots having different depth and sidewall profiles by applying active control of laser beam parameters. Blinds slots can be processed onto a workpiece, such as a tire mold or a turbine vane, for an insertion of a sipe or a sealing element, respectively. Through slots can also be processed onto a workpiece, such as a turbine element for cooling during operation or a semiconductor wafer for singulation purpose. The processing of the workpiece can include a two-step procedure, wherein the first step comprises a pre-cut. The pre-cut cuts a contour outline of a slot onto a workpiece corresponding to an element that is to be inserted into the slot. The second step comprises a removal cut to remove excess workpiece material in between the contour outline. The liquid-jet-guided laser system can employ multiple-wavelength processing of a multiple-material workpiece.

Methods for manufacturing a tire mold and displacing the air from the mold into a compression cavity during the tire making process
A tire mold or a tire mold segment can include an air compression cavity, which connects to multiple surface connection slots having dimensions between 10 and 300 microns, which can be suitable for selective removal of air in the mold. The air compression cavity, can be close to the outside ambient, allowing the air escaping the interior of the mold to be compressed, which can assist in preventing the rubber material from leaving the mold pattern surface.
A removably attached coupling assembly can be used to be attached to a laser focus optic assembly of a liquid jet guided laser system. The coupling assembly can include a coupling body, a window assembly, and a nozzle assembly. The coupling assembly thus can allow the independent and separate servicing of the window and the nozzle. For example, to service the window, the coupling assembly can be first detached from the laser focus optic assembly, exposing the top portion of the coupling assembly. The window assembly then can be detached from the coupling assembly. The window can be removed from the window assembly for servicing, such as being repaired or replaced.
