Di-El Tool was established in 1958 by Richard Ragone on the premises of high quality, on time delivery, and low costs. In 1975 the company was acquisitioned by Arthur A. Bell Jr., who has successfully maintained the original goals.

            Di-El is a long established business in Meriden, CT. We have been manufacturing aerospace parts since the beginning, for Hamilton Sundstrand, RCA, and for many other, smaller aerospace businesses.

            At Di-El Tool MFG., Inc. we have integrated all of our technology from the past to “propel” us well into the future. We have broadened our horizons from just aerospace, to working with customers in various fields, such as, automotive, electrical, medical, water filtration and agricultural.

Di-El Tool produces class-A tooling and stampings. We build single station, compound, and progressive dies. We work with many different materials such as, stainless steel, cold and hot rolled steel, aluminum, copper, brass, plastic, phenolics, and any produced material that can be stamped, machined, and fabricated. Di-El Tool has also been doing assemblies for years. We assemble cables, wires, and metal products.

“Cradle to grave” jobs are our specialty. Once a print is received, the part is designed to fit the customer’s specifications. The required tooling and dies are built, and the production is complete within a month’s time. After each process the parts are inspected. A final inspection takes place before the parts are boxed and shipped.

            Our quality system is second to none. We are AS9100 certified.  Available services include SPC (statistic process control), hardness testing, and pull force testing. Our standard functions consist of document control, scheduled instrument calibration, first article and first piece inspections.
