The open-roller process is a crucial step in the production of rubber tires, whereby molten rubber is extruded onto a rotating drum. This method involves several key steps that ensure the quality and consistency of the final product.

Firstly, the raw materials are mixed together to form a homogeneous mixture of vulcanized rubber and other additives. This mixture is then fed into the extruder, where it is melted down to a liquid state.

Next, the molten rubber is forced through a die, which defines the shape of the tire. The die is heated to ensure a smooth flow of the material, and the pressure applied helps to compact the rubber particles and create a uniform texture.

Once the rubber has been extruded onto the drum, it is subjected to heat and pressure to cure the vulcanization process. This process converts the rubber from a liquid state to a solid one, making it more durable and resistant to wear and tear.

Finally, the cured rubber is cut into individual pieces, which are then assembled into a complete tire. The open-roller process ensures that each tire is produced with consistent quality and specifications, making them suitable for use on various vehicles.
