GROMAX
is a good fit
Tight Tolerances Matter
Contacts and terminals often need consistent location, width, thickness, bend angle, flatness, slot size, tab geometry, or mating height.
Conductive Material Selection Matters
Material choice affects conductivity, spring behavior, strength, corrosion resistance, formability, and plating compatibility. Common options may include copper alloys, brass, beryllium copper, nickel silver, stainless steel, and other conductive or spring-grade materials.
Plating Affects Final Performance
Tin, nickel, silver, gold, and RoHS-compliant finishes can affect contact resistance, solderability, wear, corrosion resistance, and final assembly fit. Plating thickness should be reviewed early because it can change slot size, insertion force, and mating performance.
Spring Force Must Be Controlled
Spring contacts, fuse clips, battery contacts, and relay components may require consistent preload, deflection, contact force, and resistance to permanent set.
Burr Direction Is Function-Critical
Burrs and sheared edges can affect insertion, mating surfaces, electrical contact, operator handling, overmolding, and wear on mating components.
Progressive Die Production Is Needed
Production-volume programs benefit from progressive tooling when repeatability, throughput, part consistency, and long-term supply stability matter.
Whether you’re developing a new contact, sourcing an existing terminal, reviewing plating or burr concerns, or trying to qualify a second source, we’re happy to take a look.
