Dark factory: robotics and automation today

The dark factory, with no human workers on shift, has been promised for years but is only now starting to multiply in earnest. The Chinese and Japanese cases show a mature model; in Europe and Spain the reality is different. An honest look at what works and what is still hype.

Private 5G networks: enterprise deployments in 2025

After years of pilots, private 5G is starting to show up in plants, ports, and warehouses with cases that actually work. What changed in 2025, which deployments make sense, and where WiFi 6E or a wired network still win the comparison.

Digital twins on the shop floor: the 2025 harvest

We've spent a decade talking about digital twins on the factory floor, and today real plants in Spain have twins that actually work. Of the four typologies (asset, process, plant, and product), three have proven return; the product twin remains more promise than reality. A look at which platforms are winning, where the twin pays for itself, and what is still hype.

Metal additive manufacturing: where it stands in 2025

Printing steel, titanium, or aluminum parts is no longer a lab experiment. Metal additive manufacturing has spent a decade maturing, with stable aerospace certifications and service providers across Europe. The question is no longer whether it works, but for which parts it pays off against machining, casting, or forging.

Industrial Edge Computing: Low Latency Where Data Happens

Industrial edge computing moves processing capacity from the centralised cloud to the plant floor, the machine, or the robotic cell. Local latency (10-50 ms) is critical for process control, machine vision, and safety systems: it is a physical limit that bandwidth alone cannot solve. OPC UA, K3s, and private 5G now form a proven production-ready stack.

PLC and OPC UA: Modernising the Plant Without Stopping Production

OPC UA is the standard protocol (IEC 62541) that connects industrial PLCs to IT systems, with built-in security and rich information models that Modbus or Profibus cannot match. Incremental adoption in phases, starting with an observer-mode gateway that leaves existing PLCs untouched, lets a plant running decades-old equipment modernise without stopping production.
