Yes. That’s often a strong fit when a program needs tool transfer, repair, requalification, or added supply stability without risking fit, function, or production uptime.
INDUSTRIAL AUTOMATION
Engineered for Strength. Built for Durability.
Industrial and automation systems demand stampings that survive stress, vibration, and harsh environments. When flatness drifts, holes miss, or carriers fatigue, “minor” errors become downtime—misreads, electrical faults, and accelerated wear.
Gromax designs, builds, and verifies under one roof, proving parts in real operating conditions. We engineer for strength, stable forming, and tight repeatability so every piece stays flat, locates true, and runs clean through plating, assembly, and service.
what we
BUILD
Terminals, busbars, press-fit blades, relay arms, brackets, shields, and ground lugs built for heat, vibration, and long service.
Terminal Blades & Quick-Connect Receptacles
Field-serviceable power/signal terminations in control panels, drives, sensors, relays, and terminal blocks.
Press-Fit / Compliant Pins & Blades
Solderless or hybrid interconnects into plated-through holes for PLC racks, motion controllers, and ruggedized I/O modules.
Relay / Contactor Contact Arms
Position and load contacts for power relays, contactors, and motor starters; maintain wipe/overtravel and force under vibration/heat.
Light-Gauge Busbars & Power Links
Low-impedance distribution inside panels, VFDs, soft starters, and power supplies; minimizes I²R loss and heat rise.
Grounding/Bonding Lugs & Chassis Tabs
Protective earth bonds and chassis grounds in cabinets and machines; maintains low-mΩ continuity through paint/oxide
DIN-Rail Mount Clips & Module Retention Springs
Snap-fit retention of PLCs, drives, I/O blocks, power supplies, and relays to 35 mm/15 mm DIN rails; reliable install/service cycles.

how we add
VALUE
Uptime-Focused Design
Parts engineered for heat, vibration, and duty cycles—stable flatness, true position, and spring life that don’t drift in service.
Power Paths That Run Cool
Coined pads, smooth edges, and selective Sn/Ag on bus links and blades to lower mΩ and heat rise in drives and panels.
Press-Fit & Field-Service Ready
Compliant pins/blades tuned for insertion/retention and clean rework; quick-connects with controlled beam force.
Dimensional Control You Can Trust
Progressive dies holding ±0.0015″ features, ±0.002″ positional, GR&R ≤10% on CTQs, and inline vision.
DIN-Rail & Mechanicals That Last
Stainless/17-7PH clips and springs with coined cam ramps and wear-managed surfaces for reliable snap-in retention.
Secure, Responsive Supply
Class-A tooling, rapid tryouts, ISO 9001 & ITAR compliance, selective reel-to-reel plating, and U.S. sourcing for continuity.
frequently asked
QUESTIONS
What industrial automation components are a good fit for precision stamping?
Contacts, terminals, brackets, retainers, EMI shields, grounding clips, and precision formed parts are all strong fits—especially when the design depends on repeatable geometry, clean assembly, and stable alignment.
How do you control variation that can affect assembly or uptime?
We focus on CTQs tied to fit, alignment, and function. That includes gaging to functional datums, burr control, springback stability, and tool wear monitoring to keep parts consistent over long runs.
What should be reviewed early in an automation stamping design?
Key items include housing stack-up, connector fit, shielding or grounding contact points, burr-sensitive edges, and formed features that affect assembly speed. These issues often show up quickly on the production floor.
What should we look for in a stamping supplier for industrial automation parts?
Look for repeatable process control, strong tooling discipline, reliable inspection, and experience with parts used in alignment-critical or high-volume assemblies.
What documentation can be supported for automation programs?
Depending on the program, support can include FAI or FAIR, inspection reports, SPC, PPAP when required, and MSA or Gage R&R.
