common applications
Ultra-thin foil stampings are used where material thickness, electrical performance, flatness, clean edges, surface condition, and careful handling affect product reliability.
Residential EV Charging Station
Foil contacts, grounding foils, conductive tabs, EMI/RF shielding foils, plated contact strips, and thin power-interface features are realistic fit points inside compact EV charging hardware.
Rugged GPS Smartwatch
Foil contacts, sensor foils, grounding foils, shielding foils, charging contacts, battery tabs, flexible contact components, and compact conductive foil elements are realistic fit points inside rugged wearable electronics.
Tactical Handheld Radio
Shielding foils, grounding foils, RF contact features, board-level conductive interfaces, antenna-related contact elements, rugged connector contacts, and thin EMI/RF shield components may be used inside tactical communication systems.
PLC Interface Relay Module
Foil contacts, grounding foils, relay contact features, leadframe-style foils, terminal-interface components, formed conductive elements, and small spring contact features may support signal switching, isolation, terminal engagement, and compact electrical connection in automation panels and machine-control systems.
Insulin Pump System
Sensor foils, conductive foil elements, battery tabs, grounding foils, shielding foils, sensing contacts, connector contacts, and compact insert-molded conductive features may support wearable or body-worn medical electronics.
Waterproof Industrial Connector System
Leadframe-style foils, stamped terminals, conductive foil inserts, grounding elements, shield contacts, crimp features, and formed contact components can be positioned inside molded or overmolded connector bodies to create sealed, ready-to-plug connections for industrial automation, power, signal, hybrid connection, sensor wiring, and rugged field equipment.
when
GROMAX
is a good fit
Thin Material Must Be Controlled
Ultra-thin foil materials can distort, wrinkle, curl, bend, or shift more easily than heavier-gauge stampings. Gromax is a good fit when the part needs careful strip control, carrier design, tool support, and controlled handling from stamping through packaging.
Burr Control Is Critical
Burr size, burr direction, rollover, and edge condition can affect electrical contact, assembly fit, insulation clearance, shielding performance, sealing surfaces, and mating components. Gromax is a strong fit when edge quality needs to be managed intentionally, not treated as an afterthought.
Flatness Matters
Thin foil parts may need controlled flatness so they seat correctly, make electrical contact, laminate, bond, weld, assemble, or pass downstream inspection. Gromax is a good fit when curl, bow, twist, or edge wave could cause poor contact, misalignment, or assembly rejects.
Fine Features Are Required
Small holes, narrow webs, fine tabs, thin slots, close spacing, sensing windows, and miniature conductive features require careful die design and inspection planning. Gromax is a strong fit when the geometry is small, delicate, and needs to repeat consistently in production.
Plating Affects Final Fit and Function
Tin, nickel, silver, gold, and RoHS-compliant finishes can affect conductivity, solderability, corrosion resistance, wear behavior, thickness buildup, and final assembly fit. Gromax is a good fit when plating has to be considered early with the stamped geometry, burr direction, forming sequence, and mating surface.
Progressive Die Production Is Needed
Higher-volume foil programs often benefit from progressive tooling when repeatability, throughput, edge consistency, and stable feature geometry matter. Gromax is a strong fit when the customer needs a production-ready process for thin conductive stampings rather than low-volume one-off cutting.
Whether you’re developing a new foil contact, sourcing an existing thin-gauge stamping, reviewing burr or handling issues, or qualifying a second source, we’re happy to take a look.
