The smart manufacturing partner for demanding industries.
Stera is a manufacturing partner for industrial sectors where delivery reliability, quality, sustainability, and end-to-end management are essential. We manufacture parts, sub-assemblies, and finished products for environments where workmanship must withstand use, time, and scrutiny.
Energy, electrification, and network infrastructure
An electrifying society needs solutions where quality, delivery reliability, and controlled sourcing are critical. Stera manufactures, for example, enclosures, copper and high-precision mechanics, electrical and electromechanical assemblies, and designs and manufactures its own equipment cabinet solutions.
Mobile machinery
Mobile machinery in demanding operating environments must withstand heavy loads and varying conditions. We manufacture mechanical, electromechanical, and wiring and cable harness assemblies for industries such as mining and forestry.
Built environment, elevators, and infrastructure technology
In the built environment, products require a long lifecycle, repeatable quality, and reliable delivery. Stera’s role can begin with a single component and grow into a safe electromechanical system that includes mechanics, assembly, wiring harnesses, and testing.
Industrial equipment, automation, and robotics
Manufacturability, testability, and delivery reliability directly affect a product’s competitiveness. We design tools and production auxiliary equipment with demanding dimensional accuracy, and manufacture high-precision mechanics parts, wiring harnesses, electronics, and assemblies for equipment that must function as part of the customer’s own production or the end customer’s process.
Defense and security of supply
Products related to defense and other demanding operating environments emphasize confidentiality, operational reliability, and a resilient supply chain. Stera manufactures parts, sub-assemblies, and assemblies according to customer requirements for environments where there is no room for error.
Measurement, weather, and health technology equipment
In devices requiring precision, small details affect the operation of the entire product. Stera manufactures precision parts, electronics, wiring harnesses, and assemblies ranging from parts weighing a gram to tested units the size of a shipping container.
Why do customers choose Stera?
In demanding industrial manufacturing, the big picture is what matters. Stera manages the manufacturing chain from sourcing to mechanics, electronics, wiring harnesses, assembly, and testing. We also take responsibility when situations change.
We manufacture precision parts weighing a gram, sub-assemblies, and large industrial systems for our customers. Seven factories in Finland and Estonia provide capacity and guarantee operational reliability. An entrepreneurial way of operating keeps activities agile: decisions are made close to production, and we can react quickly to the customer’s situation even when the solution requires new investments.
Stera’s strength is not just in technology or capacity. We learn from the requirements of our customers’ business environment, know their products, and develop manufacturing together over the long term. That is why we are at our best in complex operations that require experience, open-minded thinking, and people who solve things in practice.

Contract manufacturing
Stera handles all stages of the demanding supply chain itself: sourcing, mechanics, electronics, wiring harnesses, assembly, and testing of the final product.
Sourcing and supply chain
A controlled supply chain reduces the customer’s risk. Stera integrates manufacturing, sourcing, the supplier network, and sustainability into the same whole.
