Close cooperation creates many benefits

Strengthening the cooperation between the contract manufacturer and the customer supports the customer’s competitiveness. The contract manufacturer can then participate in planning, develop individual manufacturing solutions, and invent intelligent operating models at an earlier stage.

Leden Group was created in spring 2021, when four contract manufacturers merged. Each company had a long history, and therefore considerable expertise. It was clear to us that, by combining this diverse expertise, we can serve our customers more comprehensively.

Leden Group provides metal based contract manufacturing, from design to delivery. This enhances our customers’ operations and creates increasingly intelligent solutions.

We have customers in the energy and technology industry, mechanical engineering, and the pharmaceutical industry, for example.

The benefits of smart contract manufacturing are clear. Customers want higher quality, lower costs, faster market access and improved scalability of production. At best the customer achieves all these, at the same time.

Naturally, we continue to manufacture individual components according to the customers´ specifications. This is the core of contract manufacturing. However, the highest added value will be in our ability to offer comprehensive end-to-end solutions. By doing that, we make life easier for our customers, which is our mission.
