As reshoring trends accelerate, many U.S. companies are seeking domestic partners who can meet complex, application-specific requirements. At Keystone Foam, that shift is already well underway, with a revitalized business model built not on commodity foam fabrication, but on precision-driven problem solving.
With OEMs and product developers demanding greater customization, faster turnaround, and tighter tolerances, the traditional model of foam production — large volumes of basic shapes at the lowest cost — no longer aligns with the direction of U.S. manufacturing. Custom foam manufacturing is stepping into the spotlight, and Keystone isn’t waiting for the shift — it’s leading it.
Leading through Agile Foam Fabrication
Today, the manufacturing advantage lies in agility: brands, product managers, engineers, and operators working side-by-side to deliver tight-tolerance foam solutions across a wide range of end markets.
“Success in foam manufacturing isn’t necessarily about mass volume,” says Matt Mastarone, CEO of Keystone Foam. “It’s about specificity — being able to understand the end use, the performance required, and then fabricating a product that fits that application perfectly.”
This focus on agile customization and performance resonates across industries. It’s not about competing on price — it’s about building technical expertise and delivering value that mass providers can’t replicate.
Investing in Advanced Foam Cutting and Fabrication Capabilities
Over the past 18 months, Keystone has made significant capital investments in its facilities and equipment — not just to increase capacity, but to expand what’s technically possible.
To meet growing demand for low-volume, high-complexity jobs, the company acquired a new MAXIEM 2030 five-axis waterjet cutter. Previously, intricate foam parts required multiple cuts, hand assembly, and risked tolerance drift. Now, many of those components are produced in a single pass, with cleaner edges and improved dimensional accuracy.
“This type of investment is about more than equipment. It’s about giving our team — many of whom bring decades of engineering and fabrication experience — the tools they need to deliver better outcomes,” Mastarone notes. “That’s what turns Keystone from a vendor into a true technical partner.”
Market Agnostic, Problem Obsessed
Trends in any one vertical don’t drive Keystone’s evolution. Instead, it’s guided by a single question: Can we improve performance by engineering a better foam component?
That same flexibility is helping Keystone build long-term relationships with OEMs who don’t want to be locked into one-size-fits-all production. These companies are seeking partners who can engage in technical collaboration, understand materials, and iterate quickly.
A Positive Outlook for Regional Manufacturing
Located in Derry, Pennsylvania, Keystone Foam’s strategic shift comes at a time of renewed optimism for domestic production. According to recent regional data, Pennsylvania manufacturing saw measurable growth into mid-2025, driven by reshoring initiatives, infrastructure investment, and a robust pipeline of capital projects across the mid-Atlantic.
For Keystone and its customers, this environment presents a compelling opportunity to rethink how foam is designed, fabricated, and integrated into next-generation products.
As Mastarone puts it, “We’re here for the complex, the customized, and the critical. That’s where Keystone delivers.”

FAQ
What is custom foam manufacturing?
Custom foam manufacturing involves creating foam components designed for specific applications, performance requirements, and geometries, rather than producing generic shapes in bulk.
How does Keystone lead in agile foam fabrication?
Keystone uses advanced tools, including a MAXIEM 2030 five-axis waterjet cutter, to produce intricate foam parts with clean edges, tight tolerances, and reduced production steps.
Why is customization important in foam manufacturing?
Customization ensures foam products meet the exact needs of OEMs and product developers, improving performance and reducing fit or function issues.
What makes Keystone different from mass foam producers?
Keystone focuses on engineering-driven solutions, technical collaboration, and material expertise, delivering value that high-volume, low-cost fabricators can’t match.
Which industries can benefit from Keystone’s advanced foam capabilities?
Automotive, medical, electronics, packaging, and specialty manufacturing industries benefit from Keystone’s low-volume, high-complexity foam fabrication.
Can Keystone handle short-run or low-volume foam production?
Yes. Keystone specializes in low-volume, high-complexity projects where precision and customization are essential.
Is Keystone Foam fabrication based in the USA?
Yes. All Keystone Foam products are fabricated in Derry, Pennsylvania, supporting U.S. manufacturing and reshoring initiatives.
