For over 50 years, Hunter's Micro-Metallizer pens have let professionals plate gold, nickel, silver, rhodium and more right at the bench. No tanks. No masking. No sending parts out. Just touch the pen to the spot and plate it.
Plating has always meant a shop full of tanks, chemistry, masking, and waste disposal, or shipping your parts out and waiting days to get them back. For a single worn contact or a small production run, that's absurd. The Micro-Metallizer does the same electroplating, with a handheld pen running on 12V DC. You plate exactly the spot you want, exactly when you want, without any of the shop.
If you've ever sent a part out to be plated, or written off a worn piece because plating it wasn't worth the hassle, this is the tool you didn't know you were looking for.
Each product line is purpose-built for a distinct class of plating and surface treatment work.
Self-contained, portable pen cartridges for precision spot plating. Switch between gold, silver, copper, nickel, rhodium, and more without prep time. Operates on 12V DC — no tank, no plating shop.

Bring plating in-house. For shops doing regular plating work, the Micro-Metallizer means no tank line to maintain, no outsourcing, no turnaround time. Plate on demand, switch between metals in seconds, and keep the work (and the margin) under your own roof. Aerospace MRO, electronics manufacturing, and medical instrument shops use it exactly this way.
See production use casesGot one worn connector, a thin patch on a gold contact, a clasp that's lost its plating, an antique piece that needs a touch-up? You don't need a shop for that. Spot-plate just the area that needs it, in minutes, at your own bench. Jewelers, restorers, and repair techs use the pen to save parts that would otherwise be scrapped or sent away.
See repair use casesFrom aerospace repair to fine jewelry — Hunter Products systems are deployed wherever precision surface treatment matters.
MRO facilities use plating pens to restore worn or corroded surfaces on aircraft components without full disassembly. Selective nickel or gold plating restores conductivity and corrosion resistance on electrical connectors and fasteners.
Surgeons and dentists rely on Hunter's Carbitron system for tungsten carbide coating of cutting instruments. The diamond dusting technique — invented by Hunter Products — gives edges greater hardness and longevity than any alternative.
Jewelers and restoration specialists use the Micro-Metallizer for precision spot plating of rings, clasps, and antique pieces. Switch between 14K, 18K, 24K gold, silver, and rhodium without a full tank system.
Electronics manufacturers plate gold and tin onto PCB contacts, connector pins, and edge connectors. The Micro-Metallizer's pen-tip precision avoids bridging and contamination on tight board layouts.
Hunter Products Inc. has been at the forefront of portable electroplating technology since 1970. Based in New Jersey, we develop and manufacture the instruments that professionals reach for when precision, portability, and reliability cannot be compromised.
"Our flagship innovation — diamond dusting — was developed for the medical field to give surgical instruments a harder, more precise cutting edge."
We don't make mass-market products. We make specialized instruments for people who know exactly what they're doing — and need equipment that keeps up. Every product we ship carries the engineering experience of over five decades in the trade.
