Electrical & Power
Engineered for Conductivity. Built for Compliance.
Electrical/power assemblies need components that keep form and contact pressure through heat, vibration, and finishing—when tolerance stacks slip or plating distorts geometry, you get poor fit, intermittent contact, and field failures.
Gromax designs and validates in one loop—DFM, tooling, stamping, and gaging under one roof—delivering parts that meet print and stay stable through reel-to-reel plating, automated assembly, and long service life.
What We Build
Production-ready components engineered for electrical continuity, mechanical integrity, and compliance.
Quick-Connect Terminals
Fast, repeatable field/service connections for AC/DC power paths; used in breakers, relays, thermostats, appliances, EVSE.
Busbars & Link Straps
Low-impedance current distribution and interconnects inside panels, inverters, UPS, BESS, and switchgear.
PCB & Terminal-Block Power Pins/Blades
Board-level power entry/egress; press-fit or solder tails for terminal blocks, power modules, meters, and PSU backplanes.
Fuse Clips, Battery & Spring Power Clips
Retain and contact cylindrical fuses or cells while maintaining stable contact force under heat and vibration.
Grounding/Earthing Lugs & Chassis Tabs
Bond metallic chassis/enclosures to protective earth; create low-mΩ, paint-piercing connections in panels and drives.
Circuit Breaker & Relay Contact Arms
Mechanically position and load precious-metal contacts or bimetals for switching; sets wipe, overtravel, and force in relays/breakers.
How We Add Value
Low-Loss Power Paths
Precision busbars and terminals with coined pads, tight flatness, and selective Sn/Ag to cut mΩ and heat rise.
Contact Reliability, Proven
Spring alloys and coined flex zones tuned for force, bounce, and life in relays, breakers, and switchgear.
Selective Plating at Scale
Reel-to-reel Ni/Sn/Ag/Au bands or spots with in-die masking and vision so you plate only where it pays.
Tolerances You Can Count On
Progressive dies holding ±0.0015″ with in-die sensing, SPC, and GR&R-backed PPAP/FAI.
Insert-Mold Ready Strips
Press-fit pins and carriers designed for clean transfer into molds to reduce secondary ops and scrap.
Fast Tooling, Stable Supply
Class-A die builds, rapid tryouts, ISO 9001 & ITAR compliance, and reshoring support to keep lines running.
Frequently Asked Questions (FAQ)
What materials do you work with?
Copper, beryllium copper, brass, cold-rolled steel, stainless, and nickel silver — all plating-ready.
Do you support selective plating and reel-to-reel finishing?
Yes. Carriers and pitch are designed for plater and automation compatibility.
How tight can you hold tolerances?
±0.0015″ typical on capable features, geometry and alloy dependent.
Can you help with redesign or cost-down?
Absolutely. We review station maps and strip layouts to simplify and reduce material waste while maintaining performance.
