Dosi Ltd. Was founded in 1929 by Mr. Angelo Dosi as workshop. The strong mechanical tradition allows to achieve complete cycles, from the prototype to the assembling and tests groups and final machines.

Dosi Srl performs medium-heavy carpentry complete with high-tech boring and milling machining. Our customers are all leaders in their fields, and work mainly in the precision mechanical systems, automatic machines, packaging machines, machines for plastic processing, earth-moving machinery and road building machinery. 

Currently the company operates on a covered area of 5000 square meters, in conformance to the procedures provided by the quality certification ISO 9000 to ensure the satisfaction of its customers. Always sensitive to environmental issues, Dosi is a “zero emissions” company. The photovoltaic system installed in our factory produces the internal electricity needs. Dosi has acquired at the end of 2008 the company Baruffaldi Plastic Technology, which is specialized in manufacturing extrusion machines and special machines for plastic profiles; moreover the range of automatic machines was completed by integrating in the group the brand Primac, leader in the production of plants for smooth and corrugated pipes.

In 2025, Italsigma also became part of the Dosi Group. Founded in 1982, Italsigma specializes in the design and production of customized systems for testing industrial products, with 40 years of experience dedicated to quality. The company operates in the field of materials testing, designing and manufacturing tailored systems to test products from various industries in compliance with regulatory standards. Its production program includes both highly flexible, multi-purpose testing machines—thanks to their full programmability and modular design—and specialized machines for more specific types of tests.
