Custom Transformers
We design and manufacture custom transformers using advanced core materials like laminated steel and powdered iron. Our solutions meet exact voltage, frequency, and environmental requirements for aerospace, industrial, and high-tech applications. Every unit undergoes rigorous testing to ensure compliance with CSA, UL, and MIL-PRF-27 standards.
Custom Inductors
Our custom inductors are engineered for demanding applications in aviation, renewable energy, and power conditioning. Available with core materials including ferrites, amorphous metals, and nanocrystalline, these components support currents up to 1100A with working voltages up to 12kV. All products include a 5-year warranty.
Prototyping
We support design prototypes and R&D builds with rapid turnaround times. Our engineering team collaborates on low-volume production runs and legacy replacements, leveraging over 10,000 existing designs to accelerate development cycles for switch-mode power supplies and specialized components.
Testing Services
Our quality assurance program includes dielectric strength testing up to 30kVac and environmental compliance checks. Components are evaluated against insulation integrity, thermal performance, and mechanical durability standards to ensure reliability in demanding operational conditions.
Aerospace Components
We produce MIL-PRF-27 certified components for aerospace and defense applications. Our solutions address vibration resistance, moisture protection, and weight optimization requirements. Products include specialized transformers and inductors designed for avionics, navigation systems, and military equipment.

Report
I'm an electronics technician who amongst many other things, perform repair work on Church Organ Consoles, and the electrical side of Pipe Organs. I came into a need for a multi-tap Ac-Ac transformer for a rack of cathedral chimes, the big time companies who sell organ parts to organ builders, did not want to sell to me because I did not classify as an organ builder. I found E Craftsmen Corporation while searching online for a possible alternative. I made contact with them, and they were absolutely fantastic to work with. They custom built two of the needed transformers for me and did so for a
