Read MoreOur engineered materials are trusted for performance under intense pressure and operational demands that may exist in multiple industries. Whether the challenge is extreme temperature, extreme electrical loads, or an environment with extreme corrosion, our materials are always capable. Every engineered product is created with long-lasting reliability, safety, and stability in mind. With decades of experience in researching, manufacturing, and machining high-performance insulation and composite materials, we know well the demands of real-world applications. Our customers are relying on our materials to maintain a consistent dielectric strength, structural integrity, and dimensional accuracy under all stresses. We do not accept failure. The only thing we accept is precision-engineered perfection.
Engineered and manufactured for extreme thermal, electrical, and mechanical performance.
We engineer and manufacture custom components using a wide range of electrical insulation materials, prepreg, and resin systems that are designed for the most complex applications. Whether your components need to withstand high voltage, harsh environments, or thermal cycling, we meet the challenges that others cannot. We offer consistent quality, dimensional stability, and superior resistance to heat, moisture, and the forces applied during actual mechanical use.
Thermoplastics are softenable, machinable, and reformable polymers. We fabricate the four workhorse grades that cover the vast majority of OEM thermoplastic applications.
Nylon offers an exceptional combination of mechanical strength, self-lubricating properties, and electrical insulation. Ideal for moving components, insulators, and structural parts that must perform in humid or chemically active environments.
We offer a fully integrated suite of services, from concept to production, that ensures your electrical equipment materials will meet the highest standards of function, safety, and manufacturability. Our approach is designed to manage risks, compress timelines, nd generate quality at every stage of production.
Design & Prototyping
Our engineers turn complex ideas into real solutions. With a combination of advanced modeling software and real-world know-how, we can timeline prototype for performance testing, iterative proof of concept, and product feasibility, facilitating the progression of your designs smoothly into production.
Precision CNC machining
With multi-axis machining centers, our CNC capabilities will produce very complicated parts with extreme precision and repeatability. Whether tight tolerances or complex geometries are your requirements, we can provide consistent scale and quality every time.
Fabrication
From cutting and shaping to bonding and laminating and forming and surface finishing, our fabrication team is skilled and consistent. We work with a wide range of materials and configurations, making complex builds possible. All parts are made to spec to facilitate dependable installation and future durability in mission-critical applications.
