Indak Manufacturing

What Indak Manufacturing does

Indak Manufacturing Corporation is a privately held, vertically integrated US contract manufacturer of electrical, electromechanical, and mechanical assemblies founded in 1947 in Northbrook, Illinois by brothers-in-law Jesse Cobb and John Soreng. The company operates through four wholly-owned subsidiaries (Piedmont Automotive Products, est. 1962; Southern Switches, est. 1964; Techny Plastics, est. 1972; and Borg Indak, acquired in the early 1990s) and runs approximately 220,000+ sqft of manufacturing across facilities in Northbrook IL, Delavan WI, Clarkesville GA, and Dahlonega GA. Core capabilities span design and engineering (2D AutoCAD, 3D NX, Altium Designer), surface mount PCB assembly (8 SMT lines placing over 140,000 components per hour on Universal Advantis and Genesis chip shooters), electromechanical assembly, plastic injection molding (75 to 300 ton presses, sub-gating and hot runner systems via Techny Plastics), and qualification testing (9 AOI systems, X-Ray, patented thru-hole optical inspection, life cycle, thermal shock, salt and dust fog). The company's primary customer base is automotive OEMs (described as 'various American and foreign automobile manufacturers'), with additional verticals in heavy truck, outdoor power equipment, medical devices (Class I/II), banking equipment, marine and pleasure craft, and renewable energy battery management systems.

The product portfolio centers on PCB assemblies, prototypes, electronic modules, automotive and commercial LED lighting (interior and exterior illumination with in-house color binning, driver design, and thermal management), high current switches, blower speed control resistors, automotive sensors, HVAC / climate controls, and rugged switches/controllers for harsh environments. Annual output is reported at over 12 million electronic and electromechanical assemblies and over 25,000 injection molded plastic parts per day. All four operating entities are ISO 9001:2015 registered by NSF-ISR (certificates valid through January 2027), and the company additionally holds ISO 13485:2016 certification for medical device manufacturing.

Indak generates revenue through three streams: (1) custom OEM manufacturing services (project-based contracts with design-for-manufacturability engagement, multi-year cadence, quote-based pricing via [email protected] or 847-272-0343); (2) standard catalog switches, resistors, and sensors via the indakswitches.com sub-brand and stocking distributor Koch Sales Company (Muenster, TX); and (3) LED lighting products for automotive and commercial applications. European sales are handled via T/CCI Manufacturing GmbH in Hamburg. Marketing presence is minimal, consisting of direct sales, LinkedIn, and Facebook pages. Revenue, headcount, and ownership details are not publicly disclosed.
