These days, two major trends within the European retreading sector are making the use of shearography systems increasingly necessary. First, casings are becoming harder to source due to weakness in the new tyre market and the growth in new tyre manufacturers’ involvement in retreading; they strive to retain ‘their’ casings within their own systems. Second, the focus on quality amongst medium-sized retreaders is becoming ever more important – both customers and the business’s competitive environment demand this. In an interview with Tyres & Accessories, market leader Steinbichler challenges those retreaders who continue to believe they can’t afford investments of 100,000 euros or higher: “For each of our customers, an investment in shearography has been crowned with economic success.”
