PRUMO Leather and Footwear

The Mobile Units Project (PRUMO) is a support service designed mainly to offer small enterprises on-site evaluations of their production process, work with the businessperson to identify the main technological problems, and put into practice an array of adjustments and modifications to obtain immediate results. This service focuses on aspects such as product quality, increased productivity, and reductions in cost, scrap and waste, seeking to improve the competitiveness of these companies.

PRUMO’s staff uses Mobile Units, vehicles equipped with portable laboratory equipment specialized for each industry and operated by an engineer and an IPT technician. A series of tests and analyses of raw materials are performed and deficiencies in equipment, processes and tooling, or shortcomings in personnel training are detected. Based on the diagnosis, necessary changes are suggested and feasible solutions implemented, with immediate confirmation of the results. The service is conducted on the company’s premises for a period of up to two days.

Whenever possible, technological support for micro and small enterprises is covered by non-refundable grants of 80%, while the company covers 20% of the total value with its own funds.
