Having technical knowledge and high accuracy of PU injection machines and enough knowledge of polyurethane materials enabled the manufactures to produce high-quality machines and therefore, the manufacturers active in the shoe industry were satisfied with the PU making machines of Sanat Nazari. PU SANAT NAZARI MFG.CO managed to conclude a cooperation agreement with TECHNO PUMA Company of Italy and also successfully upgraded the company's technical knowledge in the field of design and construction, and increase the quality of its machines due to the license of this large Italian company. The company also achieved sales representatives for machines produced by WINTECH companies in Italy, such as EVA, PVC, and rubber machines, and also products produced by Dream Teach Company from South Korea, including a vehicle air filter paper kilter, and after-sales service for these companies in Iran, hence it is natural to have a market share in providing services to import and sell foreign products.
