Custom Fabrication of Quality Electrical Insulation and Components


Custom Materials, Inc. is a proven source for the custom fabrication of electrical insulation and components. We personally serve major manufacturers and suppliers of electrical power generation equipment, distribution equipment, and controls. Components range from the insulation used in transformers, motors and motor controls to precision parts for the aerospace, military, medical, renewable energy, and other demanding industries.

Companies appreciate our ability to deliver metal fabrications, plastic fabrications, even complete subassemblies. But in most every case, CMI is actually delivering a custom solution to a complex engineering, design or materials challenge. In fact, CMI takes on projects that others won’t. Few fabricators can match our unique blend of 50 years of experience, reputation for innovation, skill of our team, expertise of our engineers, adherence to quality certifications, and commitment to client success.
