About Us
Italy, 16 miles north of Milan. The year is 1989: entrepreneur Antonio Colzani and wife Candida Toscano establish the family business, their eponymous Colzani Ingranaggi Srl – where “ingranaggi” stands for gearing. The young company initially focused on the hobbing and grinding of small and medium geared devices. Gradually, as the founders were flanked by the new generation – Marco and Ornella Colzani –, and market demand grew, so did the company.
Colzani Ingranaggi went from strength to strength, setting itself ever more ambitious goals: expanding and upgrading machinery, tools, testing and quality control, enlarging the covered area used as shed, increasing its highly qualified personnel.
Today, it numbers three manufacturing plants, a staff of 50 people and a total of 6,000 square meters (some 64,600 square feet): the admin building, comprising a turning and hobbing department, a second building that houses the grinding department and an air-conditioned area for testing, and a third manufacturing plant housing the large gear cutting machines, the rack department, straight-tooth bevel gears and Klingelnberg gears.
