PRORATIO, s.r.o.

What PRORATIO, s.r.o. does

PRORATIO, s.r.o. is a privately held Czech contract manufacturer founded on 21 December 1993 in Poříčí nad Sázavou, supplying safety-critical and electromechanical components primarily to the European automotive industry and, secondarily, to audio and security-system OEMs. The company operates three production sites: the original Poříčí nad Sázavou headquarters, a Sedlčany branch established in 2004, and the German subsidiary SKP Technik GmbH in Neunkirchen am Brand founded in 2000. It holds IATF 16949:2016, ISO 9001:2015, and ISO 14001:2016 certifications, qualifying it as a Tier supplier for European automotive OEM programmes.

The production portfolio spans cable harness manufacturing (single- and multi-core, flat and round cables with crimping, ultrasonic welding, soldering, and bandaging), SMT printed circuit board assembly at an annual capacity of approximately 24 million parts, vertical plastic injection moulding (BOY22s and HOTMELT low-pressure potting), rubber vulcanisation across 33 injection moulding machines for loudspeaker rings, and final electromechanical assembly. The flagship programme is airbag cable-set production for AUDI and VW at the highest automotive safety level, complemented by loudspeaker components for Dr. Kurt Müller GmbH (since 1995) and microphones/security systems for Hosiden Besson Ltd. (since 1996).

The business model is direct B2B contract manufacturing with quote-based pricing; the firm manages full material procurement, production, and logistics delivery to OEM customers. Revenue is generated via hardware sales of manufactured components and assemblies. In August 2022, founder Henry Kummer transferred his stake to Matthias Lodes (managing director of MJL Group GmbH), consolidating family/associated ownership without any disclosed external institutional capital.
