Mold for vulcanizing tires comprises a profiled surface having air deviating paths consisting of micro-channels some of which are aligned perpendicular to the surface and extending from the surface to the rear surface

摘要

Mold comprises a profiled surface (3) having air deviating paths consisting of micro-channels (4) of which 80% are aligned perpendicular to the surface and extending from the surface to the rear surface (5). An independent claim is also included for a method for producing a tire vulcanized mold. Preferred Features: The pore size of the micro-channels is 20-200 mu m, preferably 20-80 mu m. The profiled surface is made from sintered aluminum. The micro-channels are connected to a vacuum source.
