Italy’s Main Group, one of the leaders in injection machinery for shoes, has merged with another Italian company, Electromodul, a manufacturer of presses for the production of heels and many other types of products, to form a new company called Main Group Corporation. Main Group will control it with an 80 percent stake. Lorenzo Lorenzin, president of Main Group, will also run the enlarged company. A new business plan calls for joint distribution of the products of the two companies and an extension of the product range to other types of machinery, including the processing of recycled plastic materials.
