About Us


Bad Ass design and manufacturing of injection molds since 1968.

BA Die Mold Inc. has worked with some of the top OEMs in the country, lending our expertise to everything from automotive parts and home appliances to water filtration and medical products.

BA got its start when company Founder and CEO Alan Petrucci rented a small part of a plastics processing company’s plant in Rolling Meadows, IL. The company soon outgrew the space, as it did two more locations in Downers Grove, and, in 1975, B A moved to yet a larger plant in Lisle, IL. For the next 25 years, the company grew in size and in its reputation for building first quality injection molds for plastic. B A peaked at about 29 employees while in Lisle – 80 if counting Imperial Plastics, a thermoset molding company Petrucci owned for 11 years. In 1994, Petrucci's daughter Francine joined the company full time. Together they chose Aurora, IL to build a 16,000-square-foot manufacturing plant in 2001.

BA Die Mold is currently woman owned and operated by Francine Petrucci, president and a majority co-owner.




Today, BA manufactures molds for water filtration, medical, appliance controls, house wares, electrical components for automotive and caps and closures. The company is especially known for molds that generate precision threaded parts – automatic molds for threaded parts are a particular specialty . The patented PERC™ System, a servo- motor driven mold system developed for molders that utilize electric molding machines to manufacture threaded parts.  PERC was featured in Plastics Technology Magazine, MoldMaking Technology Magazine and several other trade publications, telling readers how B A Die Mold developed a system that offers precision positioning of virtually unlimited threads on any given part. The system can also be installed in  traditional, hydraulic molding machines.

In addition, rapid prototypes and short run molding projects are also very strong customer service offerings. Short production runs can help the customer bridge the gap – supplying parts to get their project up and running prior to bringing and scheduling the mold into production at their facility.

American Made

As an American mold manufacturer, BA Die Mold actively supports the American manufacturing industry because we believe it is integral to maintaining a strong United States of America. One of the ways we do this is by specifying American made mold components and mold manufacturing supplies whenever possible. This not only supports many other American companies and their employees, but it also ensures that our customers receive the highest quality molds using components that meet our discerning standards.

Count on BA Die Mold for AMERICAN ingenuity and craftsmanship and ~ at a fair price.

Our team is flexible and ready to respond quickly to support every phase of the tooling design-to-manufacture process.
