Milacron M-600: Platen Parallelism Error

Published: 2026-06-02

Quick Reference

Strain gauge readings differ >15% across tie bars. Causes uneven clamp → flash on one side, tie bar fatigue. Check: mold thickness uniformity, tie bar nut preload, linear guide wear.

Troubleshooting Protocol

Check the Controller Diagnostic Screen

Identify which zone/component triggered the alarm. Record the error code, timestamp, and any measured deviation values shown on the diagnostic screen.

Perform Visual Inspection (LOTO First)

Power down the machine and follow Lock-Out Tag-Out procedures. Visually inspect the affected component for physical damage, loose connections, polymer leakage, or carbonized material.

Electrical Testing

Using a multimeter, check resistance/continuity on the affected circuit. Verify SSR functionality and fuse integrity. Compare readings to OEM specifications.

Replace Faulty Component

Replace the failed component with an OEM-approved part. Do not substitute with generic equivalents unless validated for the specific machine model and operating conditions.

Verify and Document

Restart the machine, verify the alarm is cleared, run a test cycle, and document the root cause, repair performed, and parts replaced in the machine maintenance log.
