Sigma Italy becomes Sigma Group

We are happy to inform you that S.I.G.MA. S.r.l., specializing in manufacturing refractories for glass furnaces, has been transformed to S.I.G.


In order to meet the growing demand of our refractories, we decided to double the capacity of the vibrocast products, bringing it up to 500 tons per month.

To this end we have constructed a new plant in Plovdiv, Bulgaria, which is operational from March 2014.

Some photos of new factory under construction:


With the new factory in Bulgaria, S.I.G.MA. GROUP will become leader in Europe for glass furnace and forehearth special shapes, including feeder expendables, manufactured using an updated chemcast technology.

The new factory will enable S.I.G.MA. GROUP to ensure rapid deliveries and still be more flexible in case of emergency.

We need the same or even more support and trust you had in us for the past two decades, to work for you and to satisfy your needs.

Our sales department is at your disposal for any further information.
