What Erko does

ERKO is a Polish family-owned industrial manufacturer founded in 1981 by Roman Pętlak and currently in its third generation of Pętlak family leadership, headquartered in Jonkowo, Poland with an additional production facility in Czeluśnica. The company operates three product divisions: ELECTRO (manufacturing over 1,700 types of cable terminals and connectors for copper and aluminum cables spanning cross-sections from 0.14 mm² to 625 mm², plus a complementary range of crimping, cutting, hole-punching, and busbar processing tools), AERO (AS9100-certified aerospace component manufacturing through CNC machining, cold metal forming, deburring, and electrochemical marking with tolerances up to 0.2mm and press forces up to 200 tons), and ROBOTICS (design, construction, and maintenance of automated production lines, including collaboration with OMRON on cable harness automation).

The business generates revenue through three primary streams: hardware sales of electrotechnical components (ELECTRO), hardware sales of precision aerospace, medical, and military components (AERO), and professional services for production automation (ROBOTICS). Pricing is quote-based and not publicly disclosed, with wholesale bulk orders eligible for negotiation, and free delivery offered on orders exceeding 1,000 PLN net. Distribution combines direct sales via regional export managers (covering named territories across Europe, the Americas, Asia, and the Middle East), an official distributor network across at least nine countries, and marketplace channels (Amazon, Allegro). The company serves aerospace primes and Tier-1 suppliers (Pratt & Whitney, General Electric, Safran, Hamilton Sundstrand, MTU Aero Engines, Collins Aerospace, GKN Aerospace), electrotechnical contractors and switchgear manufacturers, and industrial customers seeking production automation.

Proprietary technologies form a core differentiator, including the SHARK® and PIRANIA screw cable connection systems (the latter awarded the Golden Lion at Energetab 2020), and the BPS Intelligent Line for busbar processing. The company holds ISO 9001 (the first such certificate issued in Poland, in 1994), ISO 14001, AS/EN 9100:2009 / AS9100D (Bureau Veritas verified) for aerospace, GOST-R for Russian market access, Polish Ship Register admission, and Electrotechnical Institute approval. It is a member of Aviation Valley, the Polish Chamber of Electro-Technology, and the Railway Chamber of Industry.
