Marangoni invests in Rovereto plant

As part of a multi-year investment plant, Marangoni has installed a state-of-the-art Banbury mixer at its Rovereto plant in Italy

 

As the deadline approaches for a possible extension of the current labeling requirements to also include retreads, the retreaded truck tire segment is rapidly evolving in terms of performance and the level of uniformity and efficiency that is required.

For the development of new product and process technologies for truck and earthmoving tire retreads, the Marangoni Group recently started implementing a multi-year investment plan worth approximately €8m. This will focus on modernization of the various production departments at Marangoni’s Rovereto plant in Italy.

It has purchased a new, latest generation mixer capable of meeting the demand for increasingly sophisticated and high performance compounds. This new Banbury – which is currently being installed and due to be operational by the end of 2015 – features rotors with variable intermeshing clearance, and can produce compounds with extensive filler dispersion, a fundamental requirement for achieving treads with very high mileage and, simultaneously, low rolling resistance. The new Banbury mixer will also improve the quality of earthmoving tread compounds, making them more competitive for heavy-duty applications.

Another important investment in recent months concerns the building of hot-cure retreads in a production island (see image above), a system that manages the entire tire retreading process fully automatically and flexibly. Constructed exclusively for the Rovereto plant, this production line features four extruders served by an industrial robot that applies the cushion gum and tread using spindles. These control the amount of rubber placed on each tire by measuring the weight and the movements performed by the robot. The whole process is managed and monitored using special prototype software that can generate profiles interactively.

The new technology applied brings significant improvements in final products, both in terms of quality and performance, making them increasingly comparable to premium new tires. The highly automated process also ensures greater flexibility and efficiency, reducing processing times and allowing more flexible management of production flows.

Elsewhere in the plant, other upgrades are being made to the vulcanization department with the purchase of presses that can house 12 sector cylindrical molds. These will further improve product uniformity by reducing the relatively frequent phenomena of ovalization and unbalance when retreading a used tire.

Massimo De Alessandri, Marangoni Spa CEO (right), said, “I’m increasingly convinced there will be many opportunities for quality retreads in the future, and this is the focus of the efforts we are making to improve processes and increase efficiency at the Rovereto plant.

“The investments we have made, exploiting the day-to-day experiences at the factory and the innovations of our group companies operating in the mechanical sector, mean we can continue to perfect our technological development process and strengthen our cooperation with other players in the sector, for whom our company has always represented the reference partner in developing their projects in the retreading sector.”
