springs & spring contacts
Built for controlled force, repeatable movement, and reliable contact.
Gromax manufactures precision stamped springs and spring contacts that provide contact force, controlled deflection, retention, return force, and repeatable movement.
We review material properties, geometry, forming, heat treatment, plating, and assembly conditions to support consistent spring performance in production.
part examples
Leaf Springs
Flat or formed springs designed to flex repeatedly while providing controlled force, preload, or return movement.
Cantilever Spring Contacts
Formed contact beams that deflect under load to maintain electrical or mechanical contact pressure.
Spring Fingers
Narrow formed fingers used for grounding, shielding, electrical contact, retention, or compliant interface applications.
Battery Contacts
Conductive spring contacts that maintain pressure against battery terminals while accommodating dimensional and assembly variation.
Retaining Springs & Spring Clips
Formed components that use spring force to hold, locate, latch, or retain another component within an assembly.
Return & Detent Springs
Stamped springs that provide return force, positional resistance, tactile response, or repeatable movement in switches, controls, and mechanisms.
Not sure where your part fits?
part design essentials
Reliable spring performance depends on how material properties, geometry, forming, deflection, and the surrounding assembly work together.
Spring Force & Deflection
Material thickness, beam length, width, formed geometry, and working travel determine the force produced through the operating range.
Material & Temper
Yield strength, modulus, conductivity, fatigue resistance, corrosion resistance, and formability guide alloy and temper selection.
Stress & Fatigue Life
Bend radii, formed transitions, stress concentrations, preload, and maximum deflection affect permanent set and cycle life.
Contact Geometry
Contact location, wiping action, mating angle, preload, and available travel influence electrical and mechanical performance.
Forming & Springback
Bend direction, grain orientation, tooling geometry, material temper, and springback must be considered when controlling final position and free height.
Edges, Plating & Contact Surfaces
Burr direction, surface condition, and finishes such as tin, nickel, gold, or silver should suit the contact interface, environment, conductivity, and wear requirements.
from DfM to Production
Gromax supports stamped pin programs from drawing review through repeatable production.
Part & DfM Review
Review the drawing, spring function, force and deflection requirements, material, tolerances, finish, mating components, and production volume.
Progressive Die Design & Build
Develop tooling for the required piercing, blanking, coining, forming, bending, and related operations while controlling critical spring geometry.
Precision Stamping & Forming
Establish a repeatable production process around free height, contact position, formed relationships, and dimensions that influence spring performance.
Plating & Secondary Operations
Incorporate selective or overall plating, heat treatment, cleaning, assembly, machining, tapping, or other required processing into the production plan.
Production Support
Support ongoing programs with tool maintenance, dimensional review, process monitoring, root-cause analysis, and corrective action.
quality & assembly fit
Inspection should verify the characteristics that determine whether the spring fits, moves, and performs correctly in the finished assembly.
Spring Geometry
Free height, beam length, width, thickness, formed profile, and overall position.
Force & Deflection
Spring force, preload, working travel, and deflection at specified test positions.
Formed Features
Bend angles, radii, offsets, tabs, retention features, and contact locations.
Contact Surfaces
Contact position, surface condition, burr orientation, and specified plating coverage and thickness.
Assembly Fit & Movement
Fit within housings or mating components, available travel, clearance, retention, and repeatability through the intended motion.
Gromax checks critical dimensions using standard measurement, fixtures, custom gaging, or functional inspection methods and reviews your certification, traceability, and inspection documentation needs.
