Oil seal rings - Import export

THP range machines are particularly appropriate for the molding of oil seals, backup rings, parts for the automotive industry and many other rubber parts. There are two series, 2RT or 3RT, depending on the number of mold platens. Of simple design for easy maintenance, they can be provided as single or double station machine. Their vacuum cover design allows for reduced curing time and therefore increased profitability. The top platen, which is inclined by 60°, is suitable for different demolding options.

Orings are universal sealing elements used to seal against liquid or gaseous median. They are suitable for static and minor dynamic applications. Orings can be used for radial and axial sealing. The sealing occurs during installation by the radial or axial compression of the crosssection. During operation, the median pressure increases the deformation of the Oring and so increases the sealing effectiveness. For best sealing effectiveness, the Oring should have the largest possible crosssection. During installation the correct groove size, compaction, elongation/compression should be ensured. By static use the compaction should be 15 30% of the crosssection. By dynamic use it should be 10 18% (hydraulic), 4 12% (pneumatic). With regard to the ID, when installed the Oring should be stretched max 6% compressed max 3%

We manufacture rough or fully balancing & sealing ring in stainless steels and copper based alloys. Large diameter and thin section parts. High dimensional stability resulting from the low and balanced internal stress.
