precision metal stamping
Precision stamped and formed components built around repeatable geometry, controlled tolerances, and production-ready tooling.
Gromax manufactures precision metal stampings for electrical, electronics, automotive, medical, aerospace/defense, industrial, and molded-assembly applications.
We support tight tolerances, consistent forming, engineered tooling, secondary processing, and documented quality, with tolerances down to approximately ±0.0001" on appropriate features.
technical capability
Gromax supports precision stamping with progressive tooling for conductive, spring, structural, and electromechanical components.
Process capability depends on geometry, material, thickness, tolerances, forming requirements, and production volume.
Materials
Experience includes copper alloys, stainless steel, beryllium copper, brass, cold-rolled steel, nickel silver, and other stampable alloys selected to match electrical, mechanical, spring, corrosion, or forming requirements.
Stamping Operations
Processes may include blanking, piercing, notching, lancing, coining, embossing, bending, forming, cutoff, and other progressive-die operations required by the part design.
Close-Tolerance Features
Critical dimensions, hole locations, formed relationships, offsets, contact geometry, and mating features can be controlled through tooling design, process planning, and appropriate inspection methods.
Formed Components
Gromax supports flat and three-dimensional stamped parts including terminals, contacts, pins, spring features, clips, brackets, shields, inserts, conductors, and other formed geometries.
Plating & Finishing Integration
Tin, nickel, gold, silver, and other specified finishes can be incorporated into the manufacturing plan through qualified finishing processes where required.
Secondary Operations
Machining, tapping, plating, hardware insertion, assembly, and other downstream operations can be coordinated as part of the complete production process.
engineering & manufacturing approach
Reliable stamping starts with understanding the part’s function and designing the process around its critical features.
The goal is a stable process that reproduces the required geometry consistently throughout production.
Part & DfM Review
Review the drawing, material, thickness, tolerances, datums, edge requirements, plating, assembly interfaces, and expected production volume.
Strip & Process Development
Determine feed direction, carrier strategy, station sequence, pilot approach, forming progression, and cutoff method based on the part geometry and tooling requirements.
Forming & Springback Control
Evaluate bend radii, grain direction, material temper, forming sequence, and expected springback where formed dimensions are critical.
Burr & Edge Management
Consider punch-to-die clearance, burr direction, fracture condition, and edge location where insertion, contact, sealing, molding, or operator handling is important.
Tooling Integration
Progressive dies are designed around the required piercing, forming, coining, and cutoff operations so critical relationships are controlled within a repeatable production sequence.
quality & production readiness
Inspection and process control should focus on the features that drive fit and function in the final assembly.
Gromax operates under ISO 9001:2015 and supports ITAR-controlled programs where applicable.
Critical Dimensions
Hole size and location, width, thickness, profile, formed height, offsets, bend relationships, and other functionally important features.
Formed Geometry
Bend angle, free height, spring position, contact location, alignment, and relationships between multiple formed features.
Edges & Surface Condition
Burr direction, edge condition, scratches, dents, tooling marks, and specified plating or finish.
Assembly & Functional Fit
Fit with mating connectors, molded housings, circuit boards, fasteners, sensors, or other components as required by the application.
Documentation & Traceability
Gromax can review customer requirements for inspection records, certifications, traceability, corrective action, and regulated-program documentation.
