Reifen Müller retreads its millionth tire

Order Reprints

Marangoni Retreading Systems Deutschland GmbH is congratulating Reifen Müller from Hammelburg, Germany after it produced its millionth tire, a Ringtread Blackline retread.

Ringtread is the only joint-free precured retreading system capable of producing retreaded tires that rival the quality of new tires, Marangoni says.

Reifen Müller operates two Ringbuilder 3000 machines, the second of which was installed in 2012. The machines offer an integrated combination of cushion gum extrusion and ring application, introduced onto the market several years ago and synonymous with maximum productivity and the highest quality.

Ringtreads adhere completely to the casing, without tension and without any deformation of the profile, guaranteeing high mileage and total safety on any type of road surface. This retreading technology, combined with the use of shearographic inspection and nail-hole detection, ensures a perfect retreaded tire.

At Reifen Müller, retreading is not an instant process. Only when the casing and the tread strips are a perfect match for each other can a quality tire live its second or third life. Reifen Müller therefore not only applies the most recent casing inspection techniques, but also the high quality of Marangoni retreading materials. The main product used is the cold retreading material for the Ringtread line, in the high-end Blackline version. In peak season, the Hammelburg factory turns out around 350 tires a day.

With Ringtread technology, the plant can produce 200 retreads in each 8 hour shift. The high level of automation guarantees high productivity, savings in labor and faster processing times. In addition, this process eliminates the wasted off-cuts of rubber resulting from preparation of tread strips. The Ringbuilder 3000 is a completely automatic machine, in which the cushion gum is applied directly onto the casing, filling any craters and allowing perfect application and rolling of the tread rings. Reifen Müller was the first tire retreading company in Europe to use this technology, and based on the results achieved, then decided to purchase a second machine.
