production drift
Identify likely causes of burrs, variation, fit problems, and inconsistent part performance
Tool wear, setup variation, material differences, plating buildup, inspection methods, secondary operations, and packaging can all affect part performance over time.
Gromax helps engineering, quality, and sourcing teams review recurring stamped-part problems and determine whether the risk may be tied to tooling, material, burr condition, finish, inspection, handling, assembly, or supplier process control.
common signs of
production
drift
Burrs or Sharp Edges Are Increasing
Tool wear, clearance changes, or poor cutoff conditions can increase burr height and change edge quality.
Burr direction and edge condition may affect assembly, electrical contact, overmolding, mating surfaces, automated handling, and operator safety.
Dimensions or Formed Features Are Moving
Hole location, bend angle, form height, flatness, coplanarity, part length, and contact position may drift because of die wear, setup changes, material variation, plating, or measurement differences.
Fit or Assembly Is Inconsistent
A part may meet individual print dimensions but still create interference, loose retention, uneven seating, difficult insertion, or inconsistent engagement in the finished assembly.
Spring Force or Retention Has Changed
Clips, contacts, terminals, and retainers can lose preload, take a set, or produce different contact force from lot to lot.
Plating Is Affecting Performance
Finish thickness, coverage, adhesion, solderability, corrosion resistance, wear, or post-plate handling can change final dimensions, contact performance, and assembly fit.
Inspection Results Do Not Agree
Suppliers, customers, and operators may report different results when datums, fixtures, methods, or acceptance criteria are unclear or do not reflect actual part function.

how the issue is
narrowed
down
1. Define the Actual Failure
We document where the issue appears, when it started, how often it occurs, and whether it affects inspection, assembly, electrical performance, or customer use.
2. Compare Parts, Lots, and Process Changes
Good and bad samples are compared against older production, recent material lots, plating batches, tool maintenance, setup changes, and packaging revisions.
3. Check Requirement-to-Function Alignment
The drawing and inspection method are reviewed to determine whether the measured characteristics truly control fit and function.
4. Identify the Most Likely Source
The evidence may point toward tooling wear, material variation, plating, gaging, secondary operations, handling, or the mating assembly.
5. Define the Practical Next Step
The next step may include:
• Die repair or sharpening
• Material or temper review
• Burr-direction or cutoff correction
• Plating or masking adjustment
• New gaging or functional inspection
• Packaging or handling changes
• Drawing or tolerance clarification
• Tooling transfer or second-source qualification
The goal is to address the cause, not repeatedly sort the symptom.
Whether you’re investigating a recurring defect, correcting production drift, or preventing another quality issue, we’re happy to review the part, tooling, and process.
