SinoArp Cures Tires with Its Global First 85” Dual-Mold Hydraulic Press

On July 5th, Sinoarp held celebrations for tires cured with its 85” press in a renowned tire plant in China. This is Sinoarp’s global first 85” dual-mold hydraulic press, another symbol of OTR curing presses. 

The press can open/close mold within 50 seconds, and cure tires with 1540mm O.D., enjoying high productivity. Its multi tie rods are placed evenly around molds to ensure well-distributed locking forces. Its fixed bottom mold, highly accurate parallelism and concentricity between top and bottom platens have paved the way to high-quality tires. The guide system of open/close is independent and free from mold-locking forces, so that it can remain the original shape eternally. 

Its specification parameters are as follows:




       No. of cavities

       Max. mold-closing   force

       Platen O.D.

       Max. mold thickness

       Min. mold thickness
