What Cemsa International does

Cemsa International S.r.l. is an Italian privately held industrial machinery manufacturer headquartered in Cologno Monzese, in the Milan metropolitan area. Founded as Cemsa-Italwares in the 1950s and operating under the CEMSA brand since 1969, the company designs and builds custom resistance welding machines (spot, projection, seam, and flash/butt welders from 15 kVA to multi-head 300 kVA DC units) and electrical upsetting machines (free and in-die configurations handling bars up to 120 mm diameter). The technology rests on the classical resistance heating principle (Q = RI²), augmented with proprietary special CNC robots (Roboroof, Robobench, Roboside, Robocomb, Roboseam), medium-frequency transformer systems, and Industry 5.0-aligned inverter welding electronics that the company states can cut energy consumption by up to 50%. Supporting offerings include flexible production cells, transfer machines, and engineering services for positioning equipment, electrodes, and power-supply integration.

The company's commercial model is quote-based custom engineering sold directly to end users, supplemented by an international network of agents, representatives, and distributors covering more than 120 countries. More than 80% of annual production is exported. Cemsa reports a catalog of roughly 29 machine models and serves seven vertical segments: automotive (seat frames, wipers, bumpers, underbody reinforcements), aerospace/railway/naval, HVAC, household appliances, gratings and mesh panels, metal furniture and cabinets, and armored and fire doors. Headcount is disclosed at 11-50 employees with no parent, subsidiary, or external investment structure identified. Revenue is not publicly disclosed and pricing is not standardized. Recent activity in 2024 includes the co-developed MRT F 2WR transversal roller welder for a US HVAC customer, the commissioning of GRG-MP-6T and GRG-MP-8T-1600 multi-head machines for European gratings manufacturers, and trade show presence at EuroBLECH 2024, BIMU 2024, and LAMIERA 2025.
