IRE-OMBA was founded in 1906 by the Earls of Sottocasa under the name

“SOCIETA’ ANONIMA OFFICINE METALLURGICHE SOTTOCASA”. Its headquarters

were at No. 14, Via Serassi Bergamo.

In 1932, the company changed its name to “Officine Metallurgiche Bergamasche

Anonima” (OMBA).Up until the early 1960s, the factory in Bergamo manufactured large-scale forged

pieces weighing up to 6,000 kg: drive shafts, piston rods, cylinder heads for large

marine engines, and large round and flat forged sections. In the die-casting field,

the company at this time specialized in a range of products for the engineering,

automotive and petrochemical industries.

It was towards the end of the 1960s that OMBA made forging the sole focus of

the company, speciali zing in the production of rings.

IRE-OMBA. FORGED IN 1906



The first ring rolling mill was installed in 1969 and remained in operation

until 1997.

In 1974, the product range was increased with a new rolling mill, to which

two hydraulic presses were added in 1975 and 1976.

This equipment – albeit revamped – is still in use today.The late 1980s saw the start of a period of radical renewal, both in terms of

production and in terms of the organizational infrastructure of the company,

which gradually evolved from a family business to a more corporate concern

– a change that has allowed OMBA to continue its expansion.

With plants in Bergamo and Seriate, and a manufacturing facility about to

open its doors in China, OMBA has now consolidated its position as a key

manufacturing company in its sector at international level among the top ten

worldwide rings producers.

QUALITY CONTROLIn

In order to guarantee a consistent level of quality for

all OMBA products, each part undergoes a series of

rigorous tests, including:

• Non-destructive testing (ultrasonic, magnetic particle,

liquid penetrant)

• Evaluation of mechanical and metallurgical properties.

Everyone makes mistakes. Ours never leave the factory.



CERTIFICATIONSFor over a century, OMBA has been developing its technical

and professional expertise – an approach that has enabled the

Company to improve the quality of its products on an ongoing

basis. It is thanks to the company’s wealth of knowledge and

skills, and its unflagging commitment to complying with thestrictest manufacturing protocols, that OMBA’s operations have

been approved by the most authoritative international institutions,

including TUV, RINA, ABS, ISO 9001, GERMANISCHER LLOYD,

Yet for OMBA, the most important form of certification remains.

Customer satisfaction is the best guarantee of quality.
