What Cober does

Cober, Inc. is a privately held U.S. industrial equipment manufacturer founded in 1966 and currently operating from a 30,000 square foot facility in Milford, Connecticut, with manufacturing operations in Stratford, Connecticut. The company designs and builds industrial microwave heating systems, infrared preheaters, hot air curing ovens, and hybrid heating systems used for rubber vulcanization, ceramic drying, pharmaceutical processing, food tempering, and other precision heating applications. Cober differentiates itself through vertical integration, manufacturing its own microwave generators in both 2450 MHz (1kW to 10kW) and 915 MHz (up to 100kW, with capabilities reaching megawatt scale) frequency bands, and embedding its proprietary Internet Diagnostics Online (iDOL) remote diagnostics platform as standard equipment across its oven product line.

Cober sells primarily to enterprise industrial customers in the automotive, infrastructure, pharmaceutical, environmental, laboratory, and food sectors, with automotive rubber vulcanization identified as the lead use case (approximately 1,000 microwave rubber curing systems deployed worldwide). The business operates a sales-led, custom-engineered equipment model: each system is configured to customer specifications across power level, length, and continuous-versus-batch architecture, with pricing not publicly disclosed. Revenue is generated through two streams — capital equipment sales (curing ovens, heating/drying systems, microwave generators) and recurring service revenue covering installation, training, preventative maintenance, refurbishments, controls programming, and remote support via iDOL.

The company has operated continuously for nearly 60 years under the same industrial heating focus, with historical depth in defense (Patriot anti-missile test systems in the 1970s-1980s) and ongoing technical collaborations, including a partnership with German microwave firm Muegge. Ownership is private with no disclosed institutional investors, no funding rounds, and no recent M&A activity in the source material. Cober has 11-50 employees and serves customers globally from its Connecticut base.
