progressive die design & build
Production tooling engineered around the part, material, forming sequence, and expected production life.
Gromax designs and builds Class A progressive dies for precision stamped components.
Tooling is engineered around part geometry, material behavior, critical dimensions, and long-term production stability.
technical tooling capability
A progressive die should do more than combine operations. It must control the strip and part through each station while maintaining the relationships that determine final fit and function.
Gromax progressive tooling can be developed around operations such as:
Blanking & Cutoff
Creating external profiles and separating completed parts from the carrier or strip at the appropriate stage of the progression.
Piercing & Notching
Producing holes, slots, openings, edge features, and relief geometry while maintaining required relationships to pilots, carriers, and subsequent forms.
Bending & Forming
Developing tabs, flanges, offsets, contacts, spring features, brackets, pins, and other three-dimensional geometries through controlled forming stations.
Coining & Localized Forming
Applying concentrated deformation where the part requires controlled thickness, localized geometry, contact features, or other coined details.
Lancing & Embossing
Producing integral tabs, raised features, stiffening details, locating features, or other geometry without necessarily separating the feature completely from the parent material.
Carrier & Strip Control
Designing carrier rails, bridges, pilots, progression pitch, and part orientation to maintain strip stability and accurate registration through the die.
engineering & die development approach
Progressive-die performance is developed before the final tool design is completed.
The goal is a stable, maintainable tool that produces consistent parts throughout production.
Part & DfM Review
Review the drawing, material, thickness, tolerances, datums, burr requirements, formed geometry, plating, assembly conditions, and expected production volume.
Strip Layout & Progression
Determine feed direction, carrier location, station sequence, pilot strategy, material utilization, and how the part will remain supported as features are progressively created.
Forming Sequence Development
Break complex bends and forms into appropriate stages to control strain, springback, distortion, and interaction between adjacent features.
Critical Feature Control
Identify which dimensions should be established in the same station, which relationships depend on pilots or carriers, and where downstream forming may move previously created features.
Tool Construction & Maintenance Strategy
Design working components so wear areas, punches, forms, and other service items can be maintained or replaced without unnecessarily disturbing the rest of the die.
tool tryout, validation & production readiness
A finished die must prove stable performance, not just cycle successfully.
When qualification applies, sampling and documentation follow the required drawing, specifications, and approval criteria.
Strip Progression
Verify feed pitch, pilot engagement, carrier stability, material tracking, station timing, scrap flow, and part release.
Stamped & Formed Geometry
Check critical dimensions, hole locations, bends, offsets, free heights, formed relationships, flatness, and other functionally important features.
Edges & Burr Condition
Evaluate cutting clearances, burr orientation, edge quality, and whether stamped edges are suitable for the mating or downstream proce
Tool Operation
Confirm that punches, forms, guides, strippers, carriers, and other working elements operate without interference, abnormal loading, or recurring manual intervention.
Inspection & Process Controls
Establish the measurements, gages, fixtures, setup checks, and maintenance points needed to support repeatable production.
tooling built for production support
Production tooling must remain stable, serviceable, and capable of maintaining part quality over time.
Gromax designs dies with real production performance, maintenance, and long-term process control in mind.
Tool Maintenance
Routine evaluation of punches, die sections, forms, guides, stripper components, and other wear areas.
Sharpening & Wear Management
Maintaining cutting conditions and replacing worn tooling details before they create recurring part-quality problems.
Tool Repair & Corrective Action
Investigating damage, dimensional drift, forming instability, premature wear, or other production issues and addressing the underlying tooling condition.
Process Review
Evaluating material behavior, lubrication, feed conditions, tooling setup, and stamping sequence when production performance changes.
Ongoing Engineering Support
Reviewing approved part revisions, process changes, and tooling modifications as the production program develops.
