Have questions about your application or material requirements?
ProPlate engineers precision electroplating for medical devices and industrial components that fall outside standard MIL, AMS, and ASTM specifications, including complex geometries, selective coverage requirements, and tight plating tolerances. Our in-house fixture and tooling fabrication means we are not limited by off-the-shelf equipment.
ProPlate electroplates onto a wide range of base materials, including copper alloys (copper, brass, beryllium copper), ferrous and nickel alloys (stainless steel, carbon steel, nickel, Nitinol), specialty materials including NdFeB magnets, and medical-grade polymer substrates including Pebax, nylon, urethane, and PET. Additional substrates are supported based on application requirements
ProPlate is ISO 13485:2016 certified across both facilities in Anoka, Minnesota, with IQ, OQ, and PQ protocol execution, in-house chemistry lab capabilities, and industry-standard inspection and testing. We are also RoHS and REACH compliant.
ProPlate connects medical device manufacturers with pre-qualified component suppliers whose capabilities are fully compatible with our plating and engineering requirements. Fewer handoffs, tighter quality control.
ProPlate prototype products are available on our website shop and through Chamfr, giving engineers direct access to gold and platinum plated components, sample kits, and specialty plated parts for early-stage development and evaluation.
Frequently Asked Questions
What industries does ProPlate serve?
ProPlate serves the medical device, dental, aerospace and defense, semiconductor and electronics, and energy technology industries. Over 80% of our clientele is in the medical device sector, where we specialize in precious metal plating for catheter-based components, implantables, and electrophysiology devices.
What metal finishes does ProPlate offer?
ProPlate offers nine metal finishes: gold, platinum, rhodium, palladium, palladium-nickel alloy, silver, nickel, copper, and tin-lead. Several finishes are available in multiple bath chemistries depending on application requirements for hardness, purity, or biocompatibility. Our primary finishes for precision electroplating for medical devices is gold, silver, and platinum.
Is ProPlate ISO certified?
Yes. ProPlate is ISO 13485:2016 certified across both facilities in Anoka, Minnesota. Both locations execute IQ, OQ, and PQ protocols and maintain in-house chemistry lab and inspection capabilities. ProPlate is also RoHS and REACH compliant.
What is selective plating and does ProPlate offer it?
Selective plating is the process of depositing metal only on specific areas of a component, leaving other surfaces unplated. ProPlate offers proprietary selective plating capabilities using various maskant application systems, allowing precise metallization on complex geometries and non-standard part shapes that go beyond traditional limitations.
Can ProPlate plate onto polymer substrates?
Yes. ProPlate metalizes onto medical-grade polymer substrates including Pebax, nylon, urethane, PET, and others. Our Meta-Poly® technology enables selective metallization of polymer balloon catheters with biocompatible, electrically conductive coatings using a low-thermal process.
Does ProPlate support prototype development?
Yes. ProPlate’s New Product Process Development (NPPD) team supports programs from initial concept through process validation and full production scaling. We develop custom plating processes, selective masking methods, and fixturing in-house for each new application. ProPlate also offers ready-to-order prototype products and sample kits for engineers in early-stage development. Visit our shop
What plating tolerances can ProPlate hold?
ProPlate maintains thickness tolerance control as low as ±5 microinches (±0.000005″). Process temperatures across our 216 plating tanks are held to within ±5°F of setpoint, maintained by 50 heat exchangers running across two 400,000 BTU/hr condensing boiler units.
Where is ProPlate located?
ProPlate operates two facilities in Anoka, Minnesota. The West Facility is 38,500 ft² and houses six production lines with 216 plating tanks. The East Facility is 12,000 ft². Both are ISO 13485:2016 certified. Contact us to get in touch with our team.
