Why is the maintenance of plastic injection molds important?
Maintaining plastic injection molds is very important, as it helps the machinery operate smoothly, saving time and costs. Proper maintenance will determine the quality of the molds for subsequent injection cycles.
Common issues when not maintaining
Although plastic injection molds can be used for a long time, infrequent maintenance can lead to serious problems, such as:
- Products becoming deformed, dented, or having holes.
- Material not being filled.
- Burn marks on the product surface.
- Products are brittle and prone to cracking or breaking.
- Color changes and oil contamination.
- Surface peeling of the plastic and flash defects (excess plastic).
Additionally, neglecting maintenance can also cause damage to the mold components, such as:
- Broken mold parts.
- Oxidation or rust on the mold surface.
- Worn or deformed components.
How to address common maintenance issues
To address issues in the maintenance of plastic injection molds, the following measures should be taken:
- Surface burning on products: Redesign the venting system add additional vents, and adjust the product thickness.
- Brittle products prone to cracking: Redesign the injection system to ensure quality.
- Surface peeling of plastic: Smooth the edges of the nozzle and runner channels.
- Color changes in products: Redesign the plastic runner system to reduce friction heat.
- Flash: Pay attention to the tightness and cleanliness of the mold parting line during maintenance.
