2 Power in motion MARANGONI, 60 years on Back in the 1950s Marangoni had already recognised the enormous advantages that retreaded tyres could represent not only for users but also for conserving the environment. Over these last 60 years Marangoni has invested human resources, time and money into achieving excellence across the entire retreading process: the compounds, technology and machinery used are all made by the Group in-house, and are constantly tested and upgraded at the Marangoni Research and Development Centre. The wide range of earthmoving tyres represents the synthesis of the intense product development work conducted in the field, with the aim to best satisfy our customers needs. It s this business intuition that has led the Marangoni Group to be recognised as a world leader in retreading. The right tyre for every application The excellent results achieved by the company in the field of compounds are also the consequence of significant investments made by Marangoni into research and development. A highly qualified team combines innovation capacity and technical skills when choosing the materials used. Thanks to the careful selection and repair of the casing, and to the compounds and tread patterns used, the performance of Marangoni retreads are equivalent to new tyres of premium brands. Testing durability and resistance to heating directly on the working surface verifies how well the compound withstands different conditions, from use in less hard till extremely hard conditions. LeadRship acquired in the field Thanks to the know how acquired in the field and to the technology used, Marangoni is currently a world leader in retreading, offering a vast product range for all applications, featuring high technology and excellent quality. Marangoni defends the environment Mindful of the future for coming generations, Marangoni is committed to defending and protecting the environment, giving tyres longer life through the retreading process. Constantly committed to sustainable development, the Marangoni Group implements and promotes an array of activities and technologies for managing the entire life cycle of the tyre. The company s exclusive know how in this context is demonstrated by ISO 14001:2004 environmental certification. 2 3

3 xclusive BAS structure for adapting the tread compounds to different tyre uses. Product development The three compound structure utilised in the retreading procedure, allows specific tread compounds for every application and exclusive compounds for the sidewall. Four types of tread compound + RSISTANC TO cuts and TARS BAS 1 compound with very low hysteresis. BAS 2 low hysteresis compound, however its mechanical characteristics are more similar to those of the tread compound, so as to ensure continuity in the rigidity of the tread section. TRAD tailor-made compound for a wide variety of uses. SIDWALL compound developed to maximise resistance to fatigue, atmospheric agents and cuts during use. W2 W1 Recommended to with stand cuts and tears. xcellent for use when operating with extreme high loads and in severe work conditions. Recommended to withstand cuts and tears at higher average speeds than with compound W2. Recommended for medium distance travel and higher speeds than the ideal levels for compound W1. H2 ven better resistance to generation of heat internally when operating on relatively even surfaces (less severe use) H1 + RSISTANC TO HATing 4 5

4 Retreading process and systems 1_SLCTING TH TYRS 2_BUFFING 3_SKIVING MOULD SYSTM Mould curing SYSTM Smooth mould curing The tread is cured inside a mould that creates the pattern due to the pressure and temperature generated by the press. The tread is cured inside a press with a smooth mould, then is grooved to the tread pattern requested. 4_RPAIRING TH casing 5_BUILDING 6_CURING AUToclav curing The tyre is cured inside an autoclave, then grooved if necessary. 7_inspCTion and finish very tyre to be retreaded undergoes several checks to ensure it s suitable for retreading. On passing the initial examination, the tyre is then buffed. This involves removing residual tread and preparing the surface for the new tread. Where necessary, the casing is repaired and prepared for the subsequent building stage, entailing application of the tread compound depending on the intended use of the tyre. At the end of the process, the tyre is ready for curing. TRAD pattrn sculpting The tread pattern is made using a blade that sculpts the rubber following precise instructions from the software that manages the machinery. Only Marangoni offers 5 years of guarantee The guarantee covers arth-moving tyres retreaded by Marangoni, against any fault that may be attributed either to the manufacturing process or to the quality of the materials used. then, Marangoni will proceed: to retread the tyre, if deemed possible or to credit the remaining value of the tyre. A tyre returned under warranty will be inspected by Marangoni s specialized technicians and if: 6 no more than 5 years have passed since the manufacture date; Marangoni can make this commitment because of the 7 non evidence of flaws is detected due to incorrect usage, impacts, implementation of high technical production standards that sharp-edges objects; are internationally recognized and the exclusive usage of high the tyre has received regular maintenance, quality materials.
