Ojala Group

Ojala Group is a pioneer in contract manufacturing. The company has almost 60 years of experience in demanding customer projects. Customers are equipment and machine manufacturers in various industries.


The new company has a long history of expertise

Leden Group is a fresh group, but its roots go back almost 60 years in 1963. Esa Ojala founded a filter workshop in his home barn. The company, Ojala-Yhtymä, already at that time began to spread its know-how through various types of subcontracting throughout the parish.

In the early 1970s, the company had its first hall in Sievi. Finnish industry was in a state of transition and needed diverse services. Jobs were also needed in small rural municipalities, which made the growth of Ojala a source of joy for the entire region.

The transition phase was also experienced in Estonia in 1990, when Favor AS was founded. The company was one of the first private limited companies in the country – previously private companies were illegal in the country. The company started with roof profiles, which are still part of the range. A decade later, Favor began to grow its contract manufacturing.

In 1997, another contract manufacturer, Celermec, was established next to Sievi Ojala Group, focusing on sheet metal mechanics, machining, painting and assemblies.

A third contract manufacturer was formed in Nivala, Sievi’s neighborhood, when LaserComp, which specializes in laser and plasma cutting, edging and welding assemblies, started operations.

Now, three contract manufacturers operating in Northern Ostrobothnia are united by industrial know-how and customer thinking, which began to grow in the region in the early 1960s. Favor Estonia has followed a similar growth path. Technology has been renewed and the operating environment has changed many times during the trip, but the desire to provide the best for the customer has remained.

In 2015, LaserComp acquired Celermec. At that point, the regional investor Arvo Sijoitusosuuskunta became an owner, playing a significant role as a midwife when Favor, LaserComp, Celermec and Ojala Group merged to form Leden Group in 2021. A new, more international journey has begun.
