prototype to production

Turning early parts into repeatable production stampings

Prototype parts can prove the concept, but they do not always show how the design will behave in a stable stamping process.

Gromax helps engineering and sourcing teams move machined, laser-cut, etched, hand-formed, or early stamped samples into production-ready tooling, inspection, finishing, packaging, and repeat supply.

when a prototype to

production

makes sense

Machined, laser-cut, etched, or hand-formed samples may not reflect the burrs, springback, edge conditions, and feature interaction created by production stamping.

Growing annual volume may justify bridge tooling, progressive dies, carrier-strip handling, custom gaging, or integrated secondary operations.

Contact geometry, spring force, bend position, flatness, coplanarity, fit, and interdependent tolerances may require a more controlled production approach.

Production coil may behave differently from prototype stock because of changes in temper, thickness variation, grain direction, hardness, coating, or availability.

Plating thickness, masking, solderability, corrosion resistance, and post-finish handling can change dimensions, contact performance, and final assembly fit.

Small, thin, plated, spring-loaded, or delicate parts may require carrier strips, trays, reels, orientation control, or protective packaging.

Critical features, functional checks, force requirements, gaging, and validation methods should be planned before production tooling is released.

parts we support

Gromax supports prototype tooling for precision stamped parts used in electromechanical, regulated, and assembly-critical products, including:

EMI/RF Shields


Stamped covers or cans that reduce electronic interference.

Stamped Inserts for Overmolding

Metal inserts designed to be molded into plastic assemblies.

Leadframes & Sensor Inserts

Precision stamped frames or inserts for electronic packages.

Wire Form Pins

Formed contacts for signal, grounding, battery, or spring-force connections.

Ultra Thin Foil

Flexible conductive components using ultra-thin foil material.

what a protoype to

production

can support

The current drawing, CAD model, sample parts, mating assembly, functional requirements, and known prototype issues are reviewed together.

Material, thickness, and temper are assessed against formability, conductivity, strength, spring performance, plating, availability, and cost.

Bends, pierces, tabs, lances, embossments, coined areas, extrusions, contact features, and cutoff geometry are reviewed for staged forming and repeatability.

Critical dimensions and datums are aligned with how the part will be formed, located, inspected, assembled, and used.

Prototype tooling, bridge tooling, limited-production tooling, or full progressive dies are considered based on volume, complexity, risk, timing, and program life.

Standard measurement, custom gages, functional fixtures, force checks, first article inspection, capability studies, and customer-specific validation can be planned before launch.

Plating, passivation, tapping, machining, deburring, hardware insertion, cleaning, assembly, and packaging are incorporated into the production route.

Initial samples, inspection results, assembly checks, tooling adjustments, maintenance planning, and packaging requirements help establish a stable repeat-production process.

Whether you are scaling an early prototype, selecting a production tooling path, or trying to prevent launch problems, we are happy to review the part.
