Tyre CuringUsing nitrogen in the tyre curing process can improve tyre quality and reduce cycle time and energy costs.

Car tyre production Curing is used to give a tyre its final shape and form.

Steam is typically used to create the heat and pressure required for curing.

However, using steam brings a number of disadvantages such as:

  • Lack of flexibility in setting individual parameters

  • High cost of steam

  • High maintenance effort

  • Need for additional protective antioxidants in some cases

  • Risk of quality impairment as a result of of local overheating following condensation.

Nitrogen-based Solution

In order to overcome these disadvantages, BOC has developed a gas-based tyre curing concept that replaces steam with nitrogen as the pressure agent.

Operators of nitrogen-operated tyre presses can select the system pressure independently of the curing temperature. The elimination of steam means that the rubber no longer overheats as a result of excessive steam, and less steam condenses in subsequent stages of the curing process.
