Early design review can identify material, tolerance, forming, plating, and tooling risks before the part is released for production.
Gromax reviews new stamped-part designs to help engineering teams confirm process fit, reduce avoidable tooling changes, and define a practical path from prototype through production.
Review pierces, slots, tabs, lances, embossments, coined areas, extrusions, bends, and cutoff features for progressive-die feasibility.
Evaluate whether the selected alloy, gauge, and temper support the required conductivity, spring performance, strength, corrosion resistance, and forming behavior.
Review bend radii, bend direction, flange length, forming sequence, and material behavior to identify cracking, distortion, or dimensional recovery risks.
Identify dimensions that may be difficult to hold consistently and confirm that datums reflect how the part will be formed, inspected, and assembled.
Determine whether burr orientation, rollover, fracture zones, or sharp edges could affect electrical contact, insertion, sealing, handling, or operator safety.
Review contact location, deflection, preload, retention force, mating geometry, and stress areas for repeatable mechanical and electrical performance.
Consider plating thickness, selective plating, masking, post-plate forming, fit after finishing, solderability, corrosion resistance, and contact-area requirements.
Evaluate whether the part should remain on a carrier for plating, overmolding, automated assembly, inspection, or reel-to-reel handling.
Identify critical-to-quality features and determine whether standard measurement, custom gaging, functional checks, or dedicated fixtures may be needed.
Review expected volume, die complexity, press requirements, secondary operations, packaging, and whether prototype, bridge, or full progressive tooling is the appropriate next step.
Overly tight non-critical dimensions can increase tooling complexity, inspection time, maintenance, and piece-part cost without improving product performance.
Limited material between holes, slots, forms, and cut edges can cause distortion, tearing, weak sections, or unstable tooling conditions.
Small radii, hard tempers, or unfavorable grain direction can increase the risk of cracking, springback, and dimensional variation.
A datum scheme based only on final assembly geometry may be difficult to reproduce or inspect consistently during progressive forming.
Uncontrolled burr orientation can interfere with mating parts, electrical contact, overmolding, sealing surfaces, or safe handling.
Plating buildup can change slot width, contact position, insertion force, flatness, solderability, and final assembly fit.
Contact force, working deflection, permanent set, fatigue life, and mating conditions should be considered together rather than as separate dimensions.
A stamped part may meet its print and still fail if surrounding components, stack-ups, insertion paths, or assembly loads are not considered.
Tapping, machining, staking, or separate hardware may sometimes be replaced by stamped forms, extrusions, tabs, or integrated retention features.
Thin, delicate, plated, or easily tangled parts may require carrier-strip delivery, trays, reels, controlled orientation, or protective packaging.
A stamped component is being designed for a new electrical, electronic, medical, automotive, industrial, or defense-related assembly.
Machined, laser-cut, etched, or hand-formed prototypes need to transition into a repeatable stamping process.
Engineering needs help comparing conductivity, strength, spring behavior, corrosion resistance, availability, or forming risk.
Critical dimensions, contact geometry, coplanarity, flatness, alignment, or tolerance stack-up may affect fit and function.
The stamping must remain stable through finishing, mold loading, insertion, handling, or downstream automation.
Annual usage is high enough to evaluate progressive dies, carrier-strip processing, automation, or integrated secondary operations.

A complete production drawing is not required for an initial review. Early concepts, marked-up drawings, sample parts, and assembly information can still provide useful manufacturability direction.
