FACTORIES
Seven factories, one network.
The expertise, machinery, and capacity of Stera’s factories complement each other. For the customer, this means options, flexibility, and reduced risk.
The multi-factory model provides operational reliability. When capacity needs to be increased or production reorganized, we can respond quickly. We also have extensive experience in automating various production stages. Automation supports production quality, efficiency, and repeatability at our factories.

Large enough to take responsibility, agile enough to adapt
Stera’s factory network provides customers with capacity, options, and operational reliability. A lean operating model keeps decision-making close to the action, allowing for quick reactions to the customer’s situation. When manufacturing requires multiple methods, assembly, testing, or production reorganization, the entire process remains in the hands of a single partner.
