We were honored to be featured recently in News12 CT’s “Made in Connecticut” series, where we had the opportunity to showcase who we are, what we build, and why it matters.
As a company founded right here in Connecticut over 50 years ago, we take pride not only in our machines, but also in the lasting partnerships, packaging innovations, and problem-solving mindset that define PDC International.
PDC was founded in 1968 by Anatole Konstantin, a mechanical engineer and immigrant with a bold vision: to build American-made automation machinery that solves real manufacturing problems. What started in a small shop in Norwalk has grown into a 30,000-square-foot engineering and manufacturing facility serving some of the most recognizable brands in the world.
We’ve stayed a family-owned business and remain laser-focused on what we do best: shrink sleeve labeling, tamper evident banding, and high performance shrink tunnels built for high speed, high volume, and continuous production.
You’ve probably seen our work without even knowing it. Our machines apply the shrink sleeves and neck bands to products like:
And countless other products in food, beverage, pharmaceutical, dairy, personal care, and industrial markets.
One of the cornerstones of our machinery is our patented mandrel-based sleeving system, a piece of hardware that plays a critical role in applying shrink sleeves with consistency and precision.
The PDC mandrel is a fixed, precisely engineered tool, manufactured to tight tolerances, over which the shrink sleeve is opened and oriented before it’s applied to the container. This allows the sleeve to open fully, align properly, and apply uniformly onto each container, whether it’s round, oval, tapered, or square.
Because sleeve application happens at high speeds and with extremely thin film materials, any misalignment, tearing, or drag can slow down production, affect package quality and reduce machine efficiency.
That’s why our mandrels are:
This is particularly important when handling ultra-thin or sustainable shrink films that require extra care.
At PDC, we don’t just build machines—we build production workhorses.
“We build machines that will last for decades,” says PDC CEO, Neal Konstantin. “That’s what we’re known for, that’s what we’ve built our reputation on, and that’s why people keep coming back to PDC.”
We design for:
Being featured in “Made in Connecticut” was a reminder of the strength that comes from staying grounded in quality and community.
While our machines ship globally, every system is designed, machined, assembled, and tested right here in our Norwalk, Connecticut facility. We control the process, from mechanical and electrical engineering, to CNC machining to wiring electrical panels, machine assembly to factory acceptance testing, so you can control your production line with confidence.
As brands move toward sustainability, new container shapes, and thinner materials, the role of precision engineering becomes even more critical. Our R&D and engineering teams continue to refine our equipment designs, film-handling capabilities, and peripheral systems to meet these evolving needs.
If you’re planning a new product line, expanding capacity, or dealing with sleeving challenges, let’s talk. We look forward to working with you!
