tooling transfer
die review
Assess Existing Dies
before Transfer, Repair, Rebuild, or Production Restart
what we
review
Tool Condition
Inspect punches, die sections, inserts, forms, pilots, retainers, springs, guides, stripper components, wear plates, and other working details for damage, wear, or missing components.
Part-to-Print Capability
Compare available sample parts and current production results against the latest drawing, revision, tolerances, and critical-to-quality requirements.
Tooling Design and Strip Progression
Review station layout, strip support, pilot strategy, forming sequence, carrier design, cutoff method, and any conditions that may affect feed stability or part consistency.
Die Set and Press Compatibility
Confirm shut height, feed direction, tonnage, bed size, stroke, material width, coil handling, and other requirements needed to run the tool in the intended press.
Maintenance and Spare-Part Needs
Identify worn components, obsolete details, high-risk wear areas, missing spares, and preventive-maintenance items that should be addressed before production restarts.
Material and Lubrication Requirements
Review material grade, thickness, temper, coil condition, grain direction, lubrication, and any past material changes that may affect forming or tool life.
Gaging and Inspection Methods
Determine whether existing gages and inspection methods are usable, repeatable, and aligned with the current print and production requirements.
Secondary Operations and Finishing
Review how tapping, machining, deburring, cleaning, heat treatment, plating, assembly, and packaging may affect final part acceptance.
Documentation and Process History
Evaluate setup sheets, maintenance records, spare-part lists, inspection reports, capability data, change history, and known production issues when available.
Safety and Production Readiness
Identify concerns related to guarding, sensors, misfeed protection, scrap evacuation, part ejection, die handling, or safe operation before the tool is released to production.
common transfer
and restart risks
The Tool Has an Unknown Maintenance History
Wear may not be obvious until the die is set and run, especially around punches, cutting sections, forms, pilots, and guidance components.
The Current Print No Longer Matches the Tool
Engineering changes may have been made without complete tooling updates or documentation.
The Die Runs but Does Not Hold Critical Dimensions
A tool may produce parts while still showing variation in flatness, form position, hole location, burr size, spring force, or overall fit.
Press Requirements Are Not Documented
The original supplier may have relied on a specific press, feed setup, lubrication method, or operator knowledge that was never formally recorded.
Replacement Components Are Missing
Custom punches, inserts, forms, sensors, or wear components may need to be recreated before reliable production can begin.
Gages Are Missing or Unreliable
Production may restart without a practical way to confirm that critical features are within tolerance.
Material Changes Affect Tool Performance
A change in temper, thickness, supplier, coating, or mechanical properties can create springback, cracking, burr, or forming problems.
Burrs and Tool Wear Have Increased Over Time
Cutting clearance, punch wear, die damage, or misalignment may be causing edge-condition or assembly issues.
Process Knowledge Was Supplier-Dependent
The prior source may have relied on undocumented setup adjustments, handwork, or inspection practices to keep the program running.
The Tool Has Been Idle for an Extended Period
Corrosion, storage damage, contamination, degraded springs, or missing records may affect restart readiness.
how the transfer
review is approached
1. Review Available Program Information
Gromax reviews the current drawing, annual volume, material, finish, production history, quality concerns, and reason for transfer.
2. Inspect the Tooling
The die is examined for wear, damage, missing details, setup requirements, safety concerns, and signs of prior repair or modification.
3. Compare Tooling to Current Requirements
The die design, sample parts, gages, and documentation are checked against the latest approved part requirements.
4. Define the Required Work
The review may result in a recommendation for cleaning, sharpening, component replacement, die repair, sensor updates, ECN changes, partial rebuild, or full replacement.
5. Establish a Trial and Validation Plan
When practical, the tool is set and sampled to evaluate feed, forming, burr, dimensional performance, scrap flow, and part handling.
6. Confirm Inspection and Qualification Requirements
First article inspection, capability studies, PPAP, gage correlation, material certification, plating validation, or customer-specific documentation are defined before release.
7. Prepare for Ongoing Production
Setup information, maintenance needs, spare components, inspection methods, and process controls are documented for repeat production.
