progressive dies
Progressive die tooling for precision stamped parts.
Gromax designs, builds, and supports progressive dies that keep tight-tolerance stamped components running clean, stable, and repeatable.
From conductive materials and spring contacts to plating, assembly-critical features, and long-term volume, we control each die station so quality stays stable after launch.

is a good fit
Production Volume Justifies Dedicated Tooling
When annual demand and program life support the investment, a progressive die can improve throughput, consistency, and long-term piece-part cost.
Tight Features Need Stable Die Control
Critical dimensions, contact areas, bend locations, and mating features often need dedicated tooling to hold repeatable results in production.
Multiple Features Need a Controlled Strip Layout
Parts with pierces, bends, forms, tabs, lances, coined areas, or other linked features benefit from a die plan that controls each station in sequence.
Material Behavior Affects Final Part Function
Springback, flatness, contact force, and fit can change based on material type, thickness, temper, and grain direction.
Burrs, Edges, and Handling Matter
Burr direction, edge condition, and part presentation should be planned early when they affect contact surfaces, insertion, overmolding, safety, or assembly.
Downstream Processes Need to Be Planned In
Plating, finishing, insert moulding, and assembly requirements should be planned around the stamped-part geometry, tolerances, and handling method.
Lower Piece-Part Cost and Greater Consistency Are Required
Dedicated stamping tooling can provide lower unit costs, faster output, and more consistent quality than short-run or lower-volume manufacturing methods.
parts we support

Progressive Die Maintenance Support
Planned maintenance helps control wear, burrs, dimensional drift, and unplanned downtime.
Spare Tooling and Replacement Details
Critical spare components are identified and prepared to reduce repair lead time and production restart risk.
Progressive Die Repair Support
Worn or damaged die sections are repaired and restored to a controlled production condition.
Tool Wear Assessment
Tool Wear Assessment
Custom Gage and Inspection Fixture Development
Custom gages and fixtures enable fast, repeatable verification of critical dimensions and functional features.
Part-Specific Inspection Method Development
Inspection methods are developed around how the stamped part is formed, located, assembled, and used.
Secondary Operation Support
Tapping, machining, deburring, staking, riveting, cleaning, assembly, and packaging are supported with appropriate fixturing and process control.
Outside-Process Coordination
Plating, finishing, heat treating, cleaning, and other outside processes are coordinated to protect dimensions, appearance, and performance.
Root Cause Analysis and Corrective Support
Tooling, material, inspection, setup, and process-related issues are reviewed to identify root causes and implement lasting corrective action.
Whether you’re launching a new stamped component, moving from prototype to production, replacing a supplier, or reviewing an existing die program, we can take a look.
