factory

FENGFU has three factories as shareholder and has been responsible for the international market of more than six cooperated factories in the filed of tyre curing bladder,tyre building bladder and inner tube.

  • INNER TUBE
    Inner tube is a circular elastic tube with a tire valve nozzle used to maintain internal pressure in a tire.
    The valve mouth is used to inflate and maintain air pressure in the inner tube.
    Inner tube should have good air tightness, heat resistance, elasticity, aging resistance and small permanent deformation, which is usually made of Butyl rubber.
    Inner tube is bearing gas container for air damping, which is auxiliary bearing pressure container used in automobile, motorcycle, bicycle, rickshaw tire inner cavity .

    General information of Vulcanization

    Vulcanization is the process of applying pressure to the green tire in a mold in order to give it its final shape, and applying heat energy to stimulate the chemical reaction between the rubber compounds and other materials.
    In this process the green tire is automatically transferred onto the lower mold bead seat, a rubber bladder is inserted into the green tire, and the mold closes while the bladder inflates. As the mold closes and is locked the bladder pressure increases so as to make the green tire flow into the mold, taking on the tread pattern and sidewall lettering engraved into the mold. The bladder is filled with a recirculating heat transfer medium, such as steam, hot water, or inert gas. At the end of cure the pressure is bled down, the mold opened, and the tire stripped out of the mold.
