1. Executive Summary 

During a manual mold-opening and closing inspection, severe tie-bar instability was detected, caused by loosened cover plate screws. This led to misalignment, accelerated wear of critical components (bushings, steel belts), and platen sinking. Corrective actions restored parallelism to 0.2mm, but worn parts require replacement. A preventive maintenance plan is proposed to mitigate future failures.

2. Findings & Corrective Actions

1) Identified Issues

-Tie Bar Misalignment: Loose cover plate screws caused tie bars to shift, creating 1mm parallelism deviation. 

-Resulting friction damage: Bronze bushings and dust seals. Steel belts and slide shoes, leading to the movable platen sinking.

-Production Impact: Risk of mold flash due to misalignment. 

2) Actions Taken

-Realigned tie bars, reducing parallelism deviation to 0.2mm.

-Secured all cover plate screws to prevent future movement. 

-Tested mold closure: Confirmed no flash during trial production.

3) Critical Replacement Parts

The following components require immediate replacement to avoid further damage: 

Worn Parts: Steel belts & slide shoes. Bronze bushings & dust seals. 

Urgency: Delayed replacement may worsen tie bar scoring and platen instability. 

4) Root Cause & Prevention Plan 

- Root Cause

Insufficient maintenance routines led to: Undetected loose fasteners. Inadequate lubrication of tie bars/bushings. Unchecked wear on sliding components. 

-Preventive Maintenance Plan 

To extend machine lifespan, implement: 

5) Recommendations for [ Client Company ]

- Schedule Downtime to replace worn parts (steel belts, bushings, seals). 

- Staff Training on daily/weekly checks (we can assist upon request). 

- Spare Parts Inventory: Keep critical components (e.g., bushings, seals) on hand.

Conclusion 

The tie-bar issue was resolved temporarily, but proactive maintenance is essential to avoid platen misalignment and costly downtime. Implementing daily/weekly checks will extend component lifespan and ensure production stability.
