Kemptron

Kemptron is a Finnish electronics manufacturing services (EMS) company specializing in power electronics. Established in 2024, it emerged from the Kemppi Group, a family-owned Finnish industrial parent that also owns Kemppi, a global arc welding company, and Kempower, a DC fast charging solutions provider. Kemptron draws on over five decades of power electronics expertise originating from Kemppi's pioneering work in welding technology, where Kemppi was the first welding company to use inverter technology in the 1970s. Kemptron focuses on high-mix, low-volume power electronics manufacturing, producing up to tens of thousands of units annually. Its core services include custom manufacturing ranging from PCB assembly to sub-assemblies and box-build manufacturing, as well as engineering and new product introduction (NPI) services that guide the entire electronics manufacturing process from concept to market, from fast prototyping to testing. The company produces electronic circuit boards, subassemblies, modules, transformers, and chokes for OEMs. Positioned as a strategic EMS partner for high-power applications, Kemptron emphasizes a customer-first approach, agility in handling complex processes, and robust power electronics designed to perform in demanding conditions and harsh environments. It also highlights sustainability, aiming for energy-efficient components, waste-minimizing designs, and transparent supply chains. Kemptron is led by a team of seasoned specialists with industry backgrounds. Its parent company, Kemppi Group, is now led by the third generation of the Kemppi family. Kemptron operates primarily from Finland, serving customers such as Kemppi, and targets OEMs requiring advanced power electronics manufacturing.

Kemptron was established in 2024 as a Finnish EMS manufacturer emerging from the Kemppi Group. Its heritage stems from Kemppi, a global arc welding company founded and headquartered in Finland. Kemppi was the first welding company to use inverter technology in the 1970s, well before it became common in other industries in the 1980s. Because proper manufacturing know-how did not yet exist, Kemppi developed and built it, and has been manufacturing power modules since then. This gave the group extensive expertise and know-how in power electronics for controlling high currents and power. Kemptron was created to focus on manufacturing robust power electronics designed to perform in the most demanding conditions and harshest environments. It draws on the know-how and technological advancements of the entire Kemppi Group, which has over five decades of experience. The Kemppi Group is a family-owned parent company of Kemptron, Kemppi, and Kempower, and is now led by the third generation of the Kemppi family. Renewal, growing the business, and expansion are described as coded in the group's DNA, with courage and will to rethink the business and make bold decisions when needed. Kemptron operates as an EMS manufacturer specializing in high-mix, low-volume power electronics, manufacturing up to tens of thousands of units annually. Its services range from PCB assembly to sub-assemblies and box-build manufacturing, as well as NPI services from concept to market. The company is led by a team of seasoned specialists with industry backgrounds.
