In those years, Manouchehri store with the management of their big boys 'Mohammad Amir Yavari' by almost 8 workers began to work, so he attempted to expand and develop of the production in this factory.

They started to produce products such as Traditional Iranian breads and cookies by six or five clay ovens.

After transferring factory to 'Narmak', they have produced everything by the traditional clay ovens. Then between the years of 1958-1993, the younger brother 'Mehdi Amir Yavari' has migrated to Germany, so he has found the new technologies. He has purchased domestic and foreign machinery in order to increase capacity and diversity of production department.

During this period, 'Seyed Khandan' and 'Narmak' stores were also added to the 'Nane Tehran' group and fed through the 'Narmak' Factory. They have produced high quality breads, so big supermarkets & key accounts of Tehran started to buy their breads.

So in 1993, the new factory and store in 'Mir Damad' by working of 45 workers and new equipment in order to diversity in the production of breads, cakes and pastries was established.

After 15 years, due to the change of strategy in the production of bread and pastry and centralizing production in one place, 'MirDamad' Store was dismantled and moved to Narmak.

During the period of presence of ‘Damien Piscioneri’, the workers trained to produce new and luxury goods.

In 1393 after the reconstruction of part of the factory and procurement of new equipment for the production of 'Sweets and Desserts' in the Nane Tehran Group's was launched.

After more than 90 years of activity in the production of bread and pastry with three generations of 'Amir Yavari Family', now Nane Tehran Group's are working with approximately 150 personnel in the area of nearly 1500 square meters.
