About P&P Industries
A recognized leader in custom plastic injection molding, P&P Industries is a family-owned manufacturer built on a disciplined, scientific approach to process control. That commitment to Scientific Injection Molding places the company among a highly select group—earning designation as one of only eight certified RJG Tryout Shops in the United States.
At the core of every program is data. Processes rooted in scientific molding principles rely on rigorous testing and real-world measurement to capture meaningful machine, mold, and material data. Nothing is assumed, and nothing is left unchecked. This empirical foundation enables repeatable, stable molding processes that support long-term quality, consistency, and performance.
Established in 1970, the organization has earned a reputation as a trusted manufacturing partner across a wide range of industries. Customers consistently rank service, quality, and reliability among the highest of their supplier base—reflecting a culture that values accountability and long-term relationships.
Good enough has never been the benchmark. Continuous improvement, reinvestment, and innovation remain central to how challenges are approached and solutions are delivered. Every project is viewed as an opportunity to refine processes, improve outcomes, and create the best possible solution—both today and for years to come.
Our History
The roots of P&P Industries trace back to the early 1970s and the entrepreneurial drive of founder Warren Pruis. At just 25 years old, Pruis was working in a tool and die shop but knew the role was not his long-term path. Alongside his brother, he identified an opportunity to build something of their own—connecting with a fellow fire department member who owned a construction business and had available storage space.
With a $3,000 investment in lathes and mills and a modest $50-per-month rental agreement, the brothers launched P&P Tool, laying the foundation for what would become a growing manufacturing operation. In 1972, the purchase of the company’s first injection molding machine marked a pivotal shift in direction. Rapid growth followed, quickly outpacing the original space and prompting a move to a larger facility just one year later.
Expansion continued throughout the following decade. In 1984, operations relocated again—this time to the former Clystic School building. As capabilities broadened beyond tooling and into full-scale manufacturing, the business officially became P&P Industries, reflecting a more diverse and integrated operation.
Recognition soon followed. The company earned its first John Deere Achieving Excellence Award in 1997, achieved ISO 9001 certification in 2002, and was named John Deere Supplier of the Year in 2005—milestones that reinforced its growing reputation for quality, reliability, and performance.
By 2012, sustained growth projections made it clear that long-term expansion would require more than incremental facility additions. With limited land availability at the existing site, the decision was made to construct a new, state-of-the-art manufacturing facility in Sterling, Illinois, located in the Meadowlands Business Park. Designed around efficiency, process optimization, and scientific manufacturing principles, the new facility positioned the organization to achieve world-class levels of performance and scalability—while staying true to the values that defined its earliest days.
