8 mm and mounted in a recess formed in a sidewall molding surface
of the tire vulcanization mold.
For efficient process control, the mold must be equipped with thermocouples that are close to the molding surface
to monitor temperature.
The local texture of the molding surface
of the cavity and also the processing conditions affected the gloss of the corresponding surface of the molded parts.
This molding element has a molding surface
adapted to mold part of the tire tread surface and a blade adapted to mold a sipe or a groove in the tread.
That will give us uniform heat transfer tram the molding surface
18 mm from the molding surface
along the entire perimeter of the cavity.
The molding element having a molding surface
intended to mold part of the tire tread surface and a blade intended to mold a sipe or a groove in the tread.
The mold element comprises a molding surface
able to mold all or part of the tread surface of this tread.
The tool is enclosed in a box of wood or other material so that the molding surface
can be entirely covered with loose plastic powder or granules.
Thereafter, the molten metal is poured onto the surface of the gypsum mold in such a way that the tubular body is buried in the mold while the slit is exposed on a tire molding surface
of the mold.
Key statement: A tire vulcanization mold cleaning method for cleaning a molding surface
of a sector of the tire vulcanization mold for molding a tread portion of a pneumatic tire by using plasma created in an atmosphere of a reaction gas which chemically reacts with dirt attached to the molding surface
of the sector.
Each mold piece has a molding surface
for forming a tread pattern of the tire tread portion, and end surfaces where adjacent mold pieces are in abutment with each other when they are assembled.
