It’s important for a manufacturer to have a basic understanding of the cleaning and repair required for proper tool maintenance. To keep a tool in the best working order, maintenance of Mold parts is essential not only when issues arise, but also routinely over time.
Overall, the condition of your injection mold affects the quality of the plastic components produced. Molds and tools are critical assets to your company, yet many manufacturers overlook maintenance needs when making a decision about selecting an injection molder. How your supplier maintains your mold can be a critical element of the success and longevity of your relationship.
Like any maintenance program, there are certain checks and procedures that should be performed regularly. For example, mold cavities and gating should be inspected for wear or damage. The ejection system should be inspected and lubricated and all surfaces cleaned with a non-toxic solvent to remove dirt and sprayed with a rust preventative. Additionally, all water lines should be flushed and drained to remove excess moisture.
Molds should also get a proper maintenance review prior to storage including:
All plates separated
The ejector system should be cleaned and lubricated
Replace and / or repair parts including ejector pins and springs, worn bushings or leader pins
When these preservation tactics are completed, molds are able to be put back into service quickly and easily.
