Inside H&H Industrial Corporation: A Custom Electronics Enclosure Fabricator Built on Precision and Pride
The press brake operator at H&H Industrial Corporation doesn't rush. He sets the back gauge, checks the program, and watches the sheet of cold-rolled steel fold into a clean 90-degree break with the kind of quiet confidence that only comes from years of repetition. Across the floor, a CNC punch press cycles through a nest of cutouts — knockout holes, cable pass-throughs, mounting patterns — each punch landing where the print says it should. The parts moving through this Pennsauken, New Jersey shop aren't decorative. They're going to end up housing printed circuit boards, power supplies, relays, and integrated circuits for customers who can't afford a fit problem or a sharp edge in the wrong place. The work is precise, or it isn't done.
That standard has held for more than five decades at H&H Industrial Corporation, and it shows in how the shop operates.
A Half-Century of Sheet Metal Discipline
Founded in the 1970s, H&H Industrial has been building custom electronic enclosures and electronic cabinets out of the greater Philadelphia region since before surface-mount technology was a mainstream concept. The company remains family-owned and operated — a fact that matters more than it might sound. In a family shop with a 50-year track record, the people making decisions about quality, lead time, and customer relationships have skin in the game. There's no corporate layer insulating the shop floor from the customer, and no quarterly earnings report driving shortcuts.
The company employs between 50 and 100 people — a size that puts them squarely in the category of capable custom fabricators who can handle real production volume without the overhead and minimum-order rigidity of a large contract manufacturer. They're big enough to tool up for a serious run, small enough to actually return your calls.
What They Build and Why It Matters
H&H Industrial specializes in custom protective enclosures for sensitive electronic components. That sounds straightforward until you think about what it actually demands from a fabricator.
Electronic enclosures aren't just boxes. They have to meet dimensional tolerances that accommodate specific PCB layouts, connector cutout positions, and mounting hole patterns. They need clean interior finishes to avoid snagging wiring harnesses or creating burr contamination risks near sensitive components. They require consistent material thickness to support hardware torque specs. When a customer hands H&H a drawing — or sometimes just a set of functional requirements — the shop has to translate that into a formed, finished structure that protects the electronics inside it through vibration, thermal cycling, and whatever else the end-use environment throws at it.
Their core product lines include:
- Electronic enclosures: Custom-formed housings for PCBs, relays, and integrated circuits across a range of industries
- Electronic cabinets: Larger rack-style and freestanding structures for more complex assemblies
- Network enclosures: Purpose-built housings designed for networking hardware and data infrastructure components
The fabrication process runs through the full sheet metal sequence — cutting, punching, forming, welding, and assembly — with the kind of integrated workflow that lets a shop control quality at each handoff rather than hoping the previous step got it right.
The Technology Behind the Tolerances
H&H Industrial runs precision sheet metal fabrication equipment across its cutting, bending, and assembly operations. For custom enclosure work, that combination matters. Flat pattern accuracy on the front end determines whether the formed part matches the print. Press brake capability and programming determine whether the bends land where they need to land across a full production run — not just the first part.

For procurement and engineering teams, the practical implication is repeatability. A custom enclosure that passes first article inspection needs to pass inspection on part 500 and part 5,000. Shops that rely on operator skill alone to hold tolerances create variability risk. Shops with proper CNC-driven forming equipment and established process controls reduce that risk in ways that matter when you're sourcing a housing for a product that goes into critical infrastructure or industrial control systems.
H&H's five-plus decades of production experience means their process engineers and operators have seen the failure modes. They know where sheet metal enclosures go wrong — warped flanges, inconsistent hole positions, sharp interior corners that weren't caught before assembly — and they build the process to prevent them.
What Makes This Shop Different
In a market where plenty of job shops will quote an enclosure, H&H Industrial's differentiation comes from a combination of factors that don't show up on a capability sheet.
Depth of experience in a specific niche. This shop has spent 50 years building structures designed to protect electronic components. That's not a side business or a capacity filler between other work. It's the core of what they do, and the institutional knowledge that comes from that kind of focused repetition is real. When their engineers look at a new enclosure drawing, they're looking at it through the lens of everything they've built before.
Family ownership with long-term accountability. The people running H&H Industrial aren't rotating through on three-year contracts. They're vested in the reputation of the shop the way only owners can be. That shows up in how they handle problems, how they invest in equipment, and how they treat repeat customers.
Regional positioning for East Coast supply chains. Pennsauken, New Jersey sits in the middle of one of the densest manufacturing and technology corridors in the country — with access to the Philadelphia metro, New York, and the broader Mid-Atlantic region. For procurement teams managing supply chain geography, that location offers real logistical advantages.
Right-sized for custom and production work. At 50–100 employees, H&H can take on genuine production volumes without the long lead times and impersonal processes of a large contract manufacturer. They're also nimble enough to support development programs and lower-volume custom requirements that larger shops won't prioritize.
