Reverse Engineering & Die Modification

Reverse Engineering & Die Modification

We can reverse-engineer legacy tooling or modify existing dies to meet updated design requirements, material changes, or compliance upgrades, reducing the need for complete tool replacement.

Tool & Die Design & Manufacturing — FAQs

Your questions answered on our progressive die design, construction, maintenance, and tooling solutions — from prototyping to full-scale production.

Lead times vary by complexity and part geometry, but a standard Class A progressive die typically takes 8–12 weeks from design approval to completion. Prototype or bridge tooling can be delivered faster.

Yes. We specialize in progressive dies engineered for insert-molding compatibility, with attention to critical dimensions, part orientation, and surface finishes to ensure successful downstream overmolding.

Absolutely. Gromax offers full in-house die maintenance, sharpening, insert replacement, and repair services to extend tool life and minimize unplanned press downtime.

Yes—we offer short-run tooling options for pilot builds, low-volume runs, and bridge-to-production phases. These are ideal for validating parts before committing to full production dies.

Yes. All critical components—such as punches, inserts, and die shoes—are manufactured in-house using CNC machining, wire EDM, and precision grinding, giving us full control over fit, accuracy, and turnaround.

ELECTRICAL & POWER

Your Challenge: High-conductivity metals and plated finishes can increase tool wear and present forming issues in progressive dies.

Our Solution: Our dies are engineered with material-specific strategies — including galling-resistant geometries, specialized coatings, and plating-friendly tool design — to ensure long-term die performance.

Your Benefit: Extended die life and smoother production of terminals, busbars, and contacts with fewer plating or form-related defects.

ELECTRONICS & SENSORS

Your Challenge: Miniature components require dies capable of holding tight clearances, micro-dimensions, and high repeatability at scale.

Our Solution: Gromax builds ultra-precise progressive dies with micro-clearance punch-to-die fits and high-cycle alignment integrity for small, intricate parts.

Your Benefit: Higher production yields, better assembly fit, and reduced defect rates for sensitive electronic and sensor applications.

DEFENSE & AEROSPACE

Your Challenge: Aerospace and defense components often involve complex forms, require DFARS-compliant materials, and must meet ITAR regulatory controls.

Our Solution: We design and build dies that conform to aerospace-grade dimensional tolerances, material traceability, and ITAR handling requirements — with robust construction for high reliability.

Your Benefit: Lower scrap rates, extended tool life, and full compliance for mission-critical stamping programs.

MEDICAL DEVICE & EQUIPMENT

Your Challenge: Stamped components for medical devices must meet tight tolerances, clean edges, and strict quality standards to ensure seamless assembly and regulatory compliance.

Our Solution: Gromax designs progressive dies tailored for precision medical geometries, validated to maintain dimensional control and edge quality over long production runs.

Your Benefit: Consistent, high-quality stampings that meet medical device standards — with minimal need for secondary finishing or rework.

INDUSTRIAL MACHINERY

Your Challenge: Varied product geometries demand flexible tooling that supports small-to-mid volume production runs without compromising accuracy.

Our Solution: We design dies with modular inserts, quick-change stations, and in-die adjustability — allowing for design changes or product evolution without full retooling.

Your Benefit: Reduced tooling costs and greater adaptability across multiple part variants or product lifecycles.

MOLDING-INTEGRATED APPLICATIONS

Your Challenge: Stamped inserts must maintain precise flatness, tolerance stack-ups, and edge conditions to function correctly in molding processes.

Our Solution: Our dies are built to produce overmold-ready stampings with tight bend control, flatness, and surface prep that support consistent mold fit and adhesion.

Your Benefit: Fewer mold integration issues, faster mold qualification, and improved bonding performance in insert-molded assemblies.
