How Mold Preventive Maintenance Extends Tool Life and Reduces Downtime

Injection molds are a significant investment—and like any precision tool, they require regular care to maintain optimal performance. At Dongxinda Mould Technology Co., Ltd., we emphasize preventive maintenance as a core strategy to help our clients maximize mold lifespan and reduce unexpected failures.

Why Preventive Maintenance Matters

Molds that run thousands of cycles daily are subjected to high pressures, heat, and mechanical stress. Without regular checks, small issues such as wear on ejector pins, contamination in cooling channels, or seal degradation can escalate into major downtime events.

Our Approach to Mold Maintenance:

• Cleaning & Lubrication after every defined cycle count

• Inspection of Critical Areas (parting line, gates, ejectors, vents)

• Cooling Channel Flushing to remove scale and debris

• Component Replacement Plans for high-wear elements (springs, seals, pins)

• Detailed Maintenance Logs provided with each tool upon delivery

We design all molds with easy-maintenance features, including quick-access inserts and standardized components to speed up service time.

By maintaining your tools properly, you’ll benefit from:

• Consistent part quality

• Extended tool life (often exceeding 1 million shots)

• Predictable production with fewer interruptions

• Lower long-term operating costs

FAQs:

• How often should an injection mold be serviced?
  It depends on cycle count and material. For example, every 50,000 shots for glass-filled plastics.

• Do you provide maintenance guidelines?
  Yes, each Dongxinda mold comes with a recommended maintenance checklist.

• Can you repair or recondition old molds?
  Absolutely—we offer refurbishing services and tooling upgrades.
