About Us-Hermetic

Hermetic Coil is a family owned and operated business. We have been providing wound coil needs to the solenoid, relay and electronic field for over 50 years. Hermetic Coil pioneered the thermoplastic sealed coil-winding concept. We also can provide for your insert molding and small molded component needs using our sister company’s (Illinois Precision) unique rotary table injection machines.  

Hermetic Coil can take your coil design, small molded part ideas and turn it into a world-class component. The advantage Hermetic Coil has is its total in house control over the manufacturing process. From tooling design to final quality control using our in house tool and die facilities and Illinois Precision molding machines we can deliver total customer satisfaction. 

Whatever your needs in the automotive, medical, electronics and specialty applications we can turn your dream product into a one stop reality.
