How Proco parts show up in the field
Every part we make ends up inside somebody's product. These are the stories behind them — the problem a customer brought us, the stamping, machined part, fastener, casting, or enclosure we built to solve it, and what changed once it hit their line.

An antimicrobial drawer for a mobile clinical cart
A medical-cart maker needed an electronics drawer that survives constant hospital disinfection. An antimicrobial-coated aluminum drawer delivered a cleanable, durable part.

A rugged analyzer case for field water-quality testing
A water-testing instrument kept getting damaged in the field. A purpose-built aluminum case made it rugged enough for the back of a truck without making it heavy.

A 1U chassis that made a network startup's product look shippable
A networking startup's hand-built enclosures fit poorly and looked like prototypes. A proper 1U chassis gave their product rack-true fit and a finish worthy of the price.

A washdown-rated cabinet for a craft brewery's controls
A craft brewery's control electronics kept dying in the daily washdown. A NEMA 4 stainless enclosure with proper sealing finally kept the water where it belonged.

A bronze cleat base built for the salt-spray life
A marine-hardware maker's stainless cleats were pitting and staining in salt service. A silicon-bronze casting gave them corrosion resistance and a finish that lasts.

A cast pedestal that stiffened a cobot for heavier payloads
A cobot integrator's welded-plate pedestals flexed under motion, hurting placement accuracy. A cast A356 pedestal added stiffness and a precise, flat mounting interface.

A stainless volute that stood up to a corrosive process
A process-pump builder's cast-iron volutes were corroding out early in chemical service. A CF8M stainless casting gave them the chemistry and the seal face they needed.

A die-cast heat sink that let an outdoor luminaire run cooler
An outdoor-lighting maker was assembling luminaire housings from extrusions and brackets. A single die-cast heat-sink body cooled the LEDs better and cut the part count.

A custom eccentric bolt that made belt tensioning tool-free
A conveyor builder's belt-tensioning slots were fiddly and slipped under load. One custom eccentric bolt turned tensioning into a simple, repeatable turn.

Reinforcing aluminum threads on a drone-mount product
Aluminum threads were galling and pulling out after a few reassemblies on a robotics mount. Helical inserts gave the soft bosses a hard, durable steel thread.

Keeping water out of an outdoor sensor with a sealing screw
Field sensors were failing after rain because water tracked in around the cover screws. A bonded-washer sealing screw closed the leak path without touching the enclosure design.

Ending stripped threads on a sheet-metal chassis line
Tapping threads directly into thin sheet metal left an instrument maker with stripped holes and field failures. Self-clinching nuts gave every hole a real, reusable thread.

Keeping a 5G amplifier cool without blowing the thermal budget
A wireless-hardware maker's amplifier was running hot in a sealed enclosure. A machined heat sink with a truly flat device interface pulled the junction temperature back into spec.

Cutting leaks and rework on a mobile-hydraulics manifold
Weeping port faces and burr-clogged cross-holes were driving rework on a hydraulics builder's manifolds. Tighter machining and deburring discipline fixed both.

A reusable surgical handle that survives 500 autoclave cycles
A surgical-instrument maker needed a reusable handle that could take hundreds of autoclave cycles without pitting or roughening. Machined 316L and an electropolish delivered it.

Holding ±0.02mm so a vision startup could ship on time
A machine-vision startup needed an optical mount rigid and precise enough to hold camera alignment on a factory floor. Five-axis machining delivered it — and scaled from one prototype to production.

Speeding up rooftop solar installs with a better splice plate
A regional solar installer was losing crew time fighting rail splices on the roof. A redesigned aluminum splice plate made the joint self-aligning and shaved minutes off every rail run.

Passing FCC emissions on the first try with a board-level shield
A wireless audio startup was failing pre-compliance emissions. A precision-stamped, solderable shield frame closed the gap and kept their launch on schedule.

Silencing a wire-harness rattle for an off-road vehicle upfitter
Warranty returns traced back to a harness that buzzed loose over rough terrain. A stamped spring-stainless clip fixed the rattle and the chafing risk in one part.

How a stamped bracket cut a panel builder's assembly bottleneck
A 15-person control-panel shop was cutting and drilling its own mounting angles. Swapping to a stamped, pre-plated bracket freed a skilled fabricator and cut a persistent assembly bottleneck.
