Our Story

When we began manufacturing ribbed rubber type in the 1960s, no one dreamed we would one day become the premier rubber type supplier in the United States, but fast forward 40-odd years and millions of pieces of type and that is exactly where we are. It's been an exciting and sometimes dizzying evolution that has seen us become the  provider of precision ribbed rubber type to over 40 countries worldwide.  

In the 1960s, Indiana Stamp began to manufacture ribbed rubber type in-house after finding that service from other manufacturers was slow and prices were high. As we perfected our processes and began receiving positive customer feedback, we recognized an opportunity for a supplier with fast service, high quality, and reasonable prices. To ensure our manufacturing process would yield only the best products, ISC invested in state-of-the-art equipment and the highest quality molds and it became standard procedure to check each and every order for precise alignment and thickness. In 1988, active marketing for the RIBtype product line began and in 1989, United RIBtype began operating as its own company.

Customer response was fantastic. RIBtype quickly became known for it's unparalleled quality, service, and precision thickness and alignment. Competitive companies could not match the quality and our share of the market quickly grew. United RIBtype is now the largest manufacturer of ribbed rubber type in the United States. All RIBtype products are proudly made in the USA at our facility in Fort Wayne, Indiana. We continue to focus on offering fast, expert service and precision quality products at competitive prices.
