Schwerdtle Stamp Company Celebrates 140 Years

The Schwerdtle Stamp Company, based in Bridgeport, Connecticut, is 140 years old (1879-2019) this year. It is owned and operated by Kathy (Schwerdtle) Saint and her brother, John Schwerdtle.

While Schwerdtle is known primarily for its plastic decorating tools and hot stamping tools, an increasing part of the business is coming from custom plastics assembly and automation applications.

In addition to the hot stamping dies, bottle decorating tools, heat transfer dies and rolls used by decorators, Schwerdtle manufactures silicone sheets and rolls, heat sealing dies, heat staking tools, custom gripper fingers (end effectors) and decorative 3D CNC engraving for sonic welding applications used by the assembly and automation industries.
