About Us

Since 1968 B A Die Mold, Inc. in Aurora, IL, has worked with some of the top OEMs in the country, lending its expertise in the design and manufacture of injection molds for everything from automotive parts and home appliances to water filtration and medical products.

B A 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. But 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. Then, in 2001, Petrucci, along with his daughter Francine, who joined the company full time in 1994 and is now its president and a majority co-owner, built a 16,000-square-foot manufacturing plant in Aurora, IL, where it is currently located. 

Today, B A 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.

  • We’ve gotten over the initial fear of new technology – once you use a PERC System, it’s a great tool. It’s compact compared to a standard rack system and takes up less room. We’ve never had an issue with any of the electronic components. It’s plug-and-play.

  • We are well satisfied with the PERC system. Simply put, it is accurate, clean and demonstrates excellent repeatability.

    Global Molder of Connectors

  • The reason we decided to purchase the PERC systems was the repeatability of the servo technology, which was a huge improvement over present unscrewing technologies. We have observed excellent reliability, quality, and productivity with this technology. No regrets.
