Local warranty repair in Spain under manufacturer control
A multi-cavity injection mold built in China developed flash during early European production. ITM diagnosed and repaired the tool locally while the original manufacturer retained the technical decision, warranty authority and customer relationship.

The situation
A warranty issue before production ramp-up
After approximately 100,000 parts, flash appeared in several cavities. Previously repaired core-steel areas showed localized damage, creating an unacceptable condition before higher production volumes.
Tool
Multi-cavity injection mold built by a Chinese manufacturer and operating in Spain.
Issue
Flash in several cavities linked to localized damage in previously welded areas.
Constraint
Limited production buffer and an approaching ramp-up made lead time important.
Governance
The Chinese manufacturer authorized the inspection and retained approval of the repair route.
The visual has been anonymized and is illustrative of the documented technical condition. It is not a dimensional inspection record.
Joint decision
Compare the repair routes before authorizing the work
ITM did not take over the warranty decision. It converted the local findings into two technical alternatives for the manufacturer to assess.
Two viable routes
New inserts were compared with localized welding and remachining.
Trade-off reviewed
Lead time, cost, durability and technical risk were made explicit.
Manufacturer approval
The original moldmaker selected the faster, lower-cost welding route.
Workshop execution
Repair only the approved technical scope
The selected route was translated into an internal workshop plan with defined operations and boundaries.
Disassemble and prepare
Relevant components were removed before welding and the affected areas were prepared for controlled local repair.
Weld and restore
Localized welding was followed by EDM re-machining to restore the required geometry and surface finish.
Document the intervention
Other observations not affecting part quality or tool operation were reported separately rather than added without approval.
Evidence and closure
The manufacturer received the proof needed to close the case
Intervention evidence
ITM prepared and shared photographic and video evidence of the completed repair with the original manufacturer and the European customer team.
Customer acceptance
The European customer confirmed acceptance directly to the original mold manufacturer, preserving the manufacturer-led communication and approval process.
Latest follow-up
The mold remains in operation with no recurrence of the reported problem.
Follow-up status confirmed on 7 August 2026. No quantified post-repair cycle or production-volume claim is made.
Why this case matters
Local capability without losing commercial ownership
The case demonstrates the SLTP model in practice: the Chinese moldmaker remained the supplier and decision-maker; ITM provided local diagnosis, repair capability, execution evidence and technical continuity in Spain.
