What This Checklist Covers
This engineering matrix is designed to isolate mechanical and interface risks on the workbench before the tool enters the press:
- Tool ID & Revision: Verify nameplates and ECN-controlled changes to ensure the build matches the latest approved engineering revision.
- Guiding & Alignment: Inspect leader pins, bushings, and wear plates to ensure zero-clearance alignment during closing.
- Shut-off Contact: Perform bluing transfer and daylight checks to verify seal integrity before injection pressure is applied.
- Ejection System: Confirm full stroke freedom and positive return to the home position using mechanical limits.
- Side Actions: Verify the sequencing and locking of slides and lifters to prevent mechanical crash or interference.
- Utility Interfaces: Cross-check water, air, and hydraulic ports against circuit maps to prevent crossed-lines or hookup delays.
- Pre-mount Readiness: Final audit of revision-controlled document packets and safety interlocks required for press mounting.
Why Inspect Before Trial?
Static inspection happens before press installation to isolate mechanical risks. By screening these items on the bench, we prevent steel crash and avoidable T0 downtime that cannot be corrected once the mold is in the machine. It ensures that the first shot is focused on process, not troubleshooting mechanical errors.
