Engineering Innovation

Our experts love a design challenge. We can provide products that conform to most market specifications including a wide range of catalogue items. Our design database includes more than 10,000 products.

Our quality assurance program further complements our ability to deliver products on time with exceptional PPM performance.

Custom Configurations

We design and manufacture single and three phase transformers using all known soft magnetic materials, sheet steel (iron and nickel types), powdered metals, ferrites and amorphous metal. Custom configurations utilize unique mountings and terminations to fit diverse product requirements. Our designers will find the best solution based on performance, lead-time and cost.

Few manufacturers have the extensive range of capabilities and processes available at E Craftsmen for parts weighing less than .03 lbs (1g) to over 500 lbs.
