Industrial Material Applications Across Critical Industries
Wm. F. McGraw and Co. is based out of Riverview, MI, and primarily develops custom-engineered components and provides industrial insulation products, designed for many important industries. Our materials offer thermal and dielectric protection, as well as structural support, and are manufactured to deliver the highest possible performance capabilities in high-demand applications. From electric vehicles of the future or replacing aging power infrastructure, our precision-fabricated materials always deliver reliable and consistent performance.
Our Application Segments
We supply materials used in various commercial and industrial applications requiring performance, dependability, and longevity. Each industry serviced utilizes precision-engineered composite and insulation materials that are appropriate for its specific operational use.
Switchgear Use
Switchgear applications need superior electrical insulation and arc-resistant materials to maintain effective operational safety. High-Voltage isolation, reduced parasitic energy loss, and preventing short circuits are very performance-specific applications for our best-in-class laminated composites and dielectric isolation barriers. Our materials utilize flame-retardant properties with the appropriate dimensional stability and mechanical rigidity to be used in switchgear for panel insulators or applications (such as barriers, cabinets, and enclosures) as well as power distribution and transmission applications.
Power Electronics
When assessing power electronics applications, thermal management and electrical insulation are critical. Our materials provide a high level of thermal dissipation with dielectric insulation suitable for use in heat exchangers, inverters, converters, and control units in various installations. These components are commonly subjected to continuous high-exhausting loads and constantly changing thermal conditions, where product reductions in energy loss, protection of sensitive circuitry to increase product lifespan in operating control systems, is essential.
Generators
For generators in industrial, utility, and transport applications, they require insulation materials that need robust electrical and thermal performance under varying service conditions of vibration, thermal loading, and voltage loading for differing periods. We supply high-performance laminated composite materials as slot liners and structural elements to maintain operational capability in using these products for the longest possible operating life to minimize interruption of service. The materials should be capable of resistance to thermal aging, electrical failure, and environmental degradation, being used in everything from portable units up to utility-scale generators.
Motor Applications
Motors used in industrial equipment, transportation, and HVAC rely on components that can offer good dielectric and mechanical behaviour. We’ve made custom materials for insulation of windings, slot fillers, and terminals to ensure maximum motor performance and long-lasting durability. Our composite and thermoplastic systems have excellent resistance to wear and thermal deformation, which is crucial to keeping equipment cool, quiet, and for long service life.
Metals Processing
Metal processing faces many challenges, including high temperature, corrosive environments, and mechanical wear or abrasion. We provide heat shields, mechanical wear plates, and thermal barriers made from composites, which will keep their structural integrity, even under extreme conditions. Further, our material will enhance safety and performance in forging, casting, and rolling applications while reducing downtime and extending the life of processing equipment.
Electric Vehicles (EVs)
EV platforms require lightweight, flame-retardant, and electrically insulated components. We offer advanced thermal insulation and dielectric insulation materials to use in battery compartments, control electronics, and power distribution systems. Our products will enable heat to be managed and help ensure safety, as well as reduce the form factor for next-generation electric mobility. With custom form factors and rapid prototyping, we can integrate quickly to support these evolving designs.
Aerospace
Aerospace applications require strict performance, weight, and flammability criteria. Our engineered composite materials are used in cabin interiors, avionics housings, and thermal insulation systems. They provide high strength-to-weight ratios, flame-resistant properties, and dimensional stability that withstand altitude and temperature changes, ensuring sustained above-average performance in the face of mission-critical challenges in both commercial and defense aircraft.
Oil & Gas
The oil and gas industry is challenging as the materials need to withstand extreme temperatures, chemical exposure, and mechanical stress. We develop insulation and structural composites for use in their downhole tools, valves, and drilling equipment. Our products can withstand corrosion and maintain their mechanical integrity to help extend the life of their tools during challenging exploration and extraction, allowing for an improvement in their safety and reliability.
Medical Devices
Medical devices require precision and biocompatible materials. We manufacture custom-engineered plastics and insulation materials used in imaging devices, diagnostic, and patient interface devices. Our materials can be certified to value-added regulatory standards while providing high chemical resistance, dielectric strength, and structural integrity. Whether used in surgical systems or diagnostic devices, we embrace innovations that are improving patient outcomes.
