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 stamped parts 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.

Export Control

how we add

VALUE

Precision busbars and terminals with coined pads, tight flatness, and selective Sn/Ag to cut mΩ and heat rise.

Spring alloys and coined flex zones tuned for force, bounce, and life in relays, breakers, and switchgear.

Reel-to-reel Ni/Sn/Ag/Au bands or spots with in-die masking and vision so you plate only where it pays.

Progressive dies holding ±0.0015″ with in-die sensing, SPC, and GR&R-backed PPAP/FAI.

Press-fit pins and carriers designed for clean transfer into molds to reduce secondary ops and scrap.

Class-A die builds, rapid tryouts, ISO 9001 & ITAR compliance, and reshoring support to keep lines running.

frequently asked

QUESTIONS

Yes. In electrical and power applications, small variation in contact geometry, spring force, burr condition, or plating interface can affect heat, resistance, and product life. We focus on the features that directly impact conductivity, fit, and repeatable electrical behavior.

We look beyond the flat print. We review how plating build-up, formed geometry, and mating interfaces affect final fit and function in the assembly. That helps reduce issues with seating, alignment, and electrical contact after production starts.

Yes. These programs often involve tighter packaging, higher current demands, and more sensitive contact interfaces. We’re a strong fit when the stamped part has to maintain stable geometry and repeatable performance in compact, high-demand electrical assemblies.

Yes. Many buyers are looking for U.S.-based or second-source stamping support to reduce lead-time risk, import exposure, and dependence on a single supplier. We’re often a fit for reshoring or supplier-transition programs where continuity matters.

Yes. We can support lot traceability, inspection reporting, and other quality deliverables as required. That helps procurement teams meet internal documentation needs and support regulated, utility, or infrastructure-driven programs.

We focus on long-run repeatability through tooling discipline, inspection aligned to functional requirements, and monitoring of features that tend to drift over time. The goal is simple: stable quality, stable fit, and fewer surprises across production lots.
