Our History

Mücait Öngör, after combining his education on modelling with a mastership on foundry, installed Önmetal Döküm in 1969 as a model workshop. The company started it activities in the foundry sector in 1980 by casting parts for the automotive industry. The fact that the natural gas heating boilers have increased following commencement of use of natural gas in Turkey leaded the company to take a strategic decision in 1993 and start producing the first cast iron boiler with its own unique design and therefore step into heating sector.

After this, it became producer of many different cast iron boilers that can operate with different types of fuel. Following its path with the motto of continuous improvement, the Company as a result of projects regarding producing more environmental and more productive goods, has started its Research & Development activities in 2007 for manufacturing condensing boilers with aluminum casting exchanger. Our young and dynamic team following up innovations and legal regulations not only in Turkey but also throughout the world and positioning accordingly has launched in 2011 the wall hung full condensing boilers between 70-190 kW capacity and in 2015 the high capacity floor standing boilers (220 kW-760 kW). Our team of engineers aim to relieve Turkish heating sector from external dependence and bring it to a further level in terms of technology and design. Within the scope of our ongoing projects mega boilers with 2800 kw and the first national casting combi boiler exchanger that is allowing for a faster and more efficient burning by keeping the surface area larger with a cylindrical burner can be listed.

The Company keeps growing every day with its own equity capital and 70% of its product sales are exportation.

Our products are designed under our Research & Development department, and launched to the market after being tested in our laboratories during all production phases. All our products meet CE, GOST-R and TSE (Turkish Standards Institution) standards while our company holds ISO 9001 certificate and complies with the productivity, health, environmental protection and security criteria required by these standards.

The biggest aspire of Mücahit Öngör, who is the founder of our Company and aims to gain added value while growing at the same time, is to build a vocational high school and provide job opportunities for its graduates.
