Meaning
Operational asset tracking and physical control procedures govern the storage, servicing, modification, and handoff of injection moulds, stamping dies, and auxiliary tooling between maintenance personnel and production crews. Dedicated maintenance facilities record tool wear, cavity damage, parting line integrity, and preventative maintenance schedules across the operating life of each tool. The boundary applies to the physical handling, rack storage, and bench refurbishment of production tooling inside the plant gates.
Molded component dimension validation ceases once parts leave the quality inspection station for assembly.
Custody Transfer
Shift transitions require signed documentation before multi-cavity injection moulds transfer from storage racks to production machine platens. During formal handover, toolroom custody verifies that ejector pins, cooling channels, hot runner manifolds, and electrical thermocouple connections match production job specifications. Toolroom technicians inspect core pins and cavity polish for scratch defects, venting burn marks, or polymer flash buildup before releasing the mould to production setup technicians.
Neglecting this handover protocol leads to running worn moulds that induce severe part flash, vacuum sink marks, or improper ejection pinning. Tool condition remains verified through written inspection records.
Mould Maintenance
Tool durability directly dictates dimensional tolerances across high-volume plastic component runs. Regrind resin processing accelerates abrasive wear on gate inserts and runner walls, necessitating frequent toolroom custody check-ins for surface refurbishment and ultrasonic cleaning. Toolroom personnel monitor cavitation alignment, replacing worn brass guide bushings to prevent core shift under high clamping pressures.
When tool records reflect poor maintenance, tooling failure risks escalate into emergency production downtime and unrecoverable cavity damage.
Asset Traceability
Mould tracking systems establish accountability for engineering changes and cavity steel alterations. Serialized tool cards verify cavity steel hardness, surface coatings, and preventive shot-counter thresholds. Complete toolroom custody preserves expensive precision moulds across millions of production cycles.
