Subsidiary of Summa Defence Oyj, Lännen Tractors Oy and Lainisalo Defence Painting Oy, have signed an agreement under which Lännen Tractors’ surface treatment operations in Loimaa will be transferred to Lainisalo Defence Painting Oy. As part of the arrangement, Lainisalo Defence Painting Oy will acquire the paint shop including its equipment, and a total of five employees from the Loimaa surface treatment operations will transfer to the company as existing employees.
The outsourcing supports Lännen Tractors Oy’s strategic focus on the manufacturing and assembly of multi-purpose machines and enables controlled growth of production volumes. At the same time, surface treatment is transferred to a partner with long and well-established experience in demanding defence and government customers, strict quality requirements, and high delivery reliability.
Through the arrangement, Lännen Tractors Oy gains access not only to the Loimaa unit but also to the entire six-site network of the Lainisalo Group, two of which are located in Estonia. The network provides significant capacity and delivery flexibility and improves the predictability and quality of surface treatment across the supply chain.
The arrangement also supports the growth strategy of the Summa Defence Oyj Group and strengthens Lännen Tractors Oy’s ability to respond to growing demand in the defence sector quickly, reliably, and in accordance with high quality standards.
“The arrangement supports our focus on our core business and improves our delivery capability as volumes grow. Lainisalo Defence Painting Oy’s strong and long-standing experience with demanding defence customers, certified processes, and delivery reliability is a clear strategic advantage for us,” says Veli Ollila, CEO of Lännen Tractors Oy.
“It is important for us to support Lännen Tractors Oy in its growth and delivery reliability. The arrangement now concluded is an important part of the overall strategy of the Lainisalo companies. We will develop the Loimaa paint shop operations in the long term as part of the Lainisalo Group’s network, ensuring that Lännen Tractors Oy has access to a flexible, high-quality and scalable surface treatment solution,” comments Pertti Lainisalo, CEO of Lainisalo Defence Painting Oy.
