Coiltek Electronics

What Coiltek Electronics does

Coiltek Electronics (legal entity Coiltek Manufacturing Pty Ltd) is an Australian privately held precision manufacturer founded in 2004 and headquartered in Salisbury South, South Australia. The company specialises in custom-wound electromagnetic components — including coils, transformers, toroids, chokes, inductors, solenoid coils, and bonded coils — manufactured to client specifications using semi-automatic winding machinery supported by skilled manual winding processes. Coiltek serves enterprise customers across defence, mining and mineral exploration, medical devices, space and satellite, rail and transportation, audio, environmental sensing, communications, and automotive/electric vehicle sectors, with anchor relationships spanning more than eight years in production programs such as the Hexagon Group BMM transmitter line at over 6,000 units per month.

The company's offering extends beyond wound components into two complementary service lines: electronic assembly (PCB assemblies, wiring looms, magnetic and solenoid assemblies, transmitter assemblies, battery assemblies, and electro-mechanical builds combining wound products with plastic mouldings, metal components, and connectors) and industrial 3D printing using Markforged X7, Onyx One, and Onyx Pro printers for carbon fibre, ONYX, and fibreglass-reinforced prototyping and low-to-mid volume production. Notable process capabilities include SprayBot robotic electromagnetic shielding, self-bonding wire processing for miniature coils, and CNC-controlled epoxy encapsulation. All operations run under an ISO 9001:2015 certified quality management system.

Coiltek operates a sales-led, quote-based go-to-market model with no public pricing, no e-commerce channel, and direct engagement through website contact forms and phone inquiries. The company pursues long-term engineering partnerships from concept and co-design through prototyping, validation, and full-scale production, emphasising Australian sovereign manufacturing and supply chain security. Beyond its domestic Australian base, Coiltek exports consumer metal detector coils to over 36 countries.
