Location Ossam AD is situated in the Central North part of Bulgaria, in the city of Lovech 170 km from Sofia by road 2 hours by car

Company history 1980 – The company was established with main scope of activities – mass production of castings of spheroidal-graphite cast iron 1997 – The company was privatized by Metal Technology Group Angel Balevski Holding AD. Since then Ossam AD is a member company of MTG 2001 – Ossam AD is the first Bulgaria foundry certified according to ISO 9001 2010 – production of ADI material is started In the next years new processes, methods and materials were implemented, investments in equipment and software were made and all this lead to increasing of the effectiveness and quality of the production 2015 - A major investment was made and a new moulding line DISAMATCH 24/28 together with an automatic sand quality control mixer were bought and put in operation 2016 – 2017 – new CNC machines were bought and installed in the plant, new machining shop was fully equipped 2019 – “no bake” casting method was implemented in the production

Facilities Established: 1980 Open area: 69 000 sq.m. Covered area: 56 167 sq.m. Employees (2019): 200 Export share (2019): 67 % Production is organized in 3 levels: • Melting of the metal on the top • Casting and deburring in the middle • Shaking out and cleaning of the parts on the ground floor

Production capabilities: Ductile cast iron – 85% Grey cast iron – 15%. Main production methods: • Mould sand casting of grey and ductile cast iron • No bake casting of parts Machining, Painting, Assembling
