The life length of the die is affected by many aspects.The annual maintenance procedure required for each injection molding position depends on the different mold cycle.The following are some experiences and skills of borun mould parts for overhaul of mould parts.
- Check for the warning signs of rust or humidity in the air vent
If you find a rusting or humidity near a hot flow vent, that means an internal condensation or a potential rupture of the water pipe.A damp phenomenon can cause a fatal short circuit to the heater.If the machine is not running all year round and needs to be turned off at night or on weekends, the chance of such a phenomenon increases.
- Check whether there are signs of wear in the guide column and the guide suite
Find out whether there are any marks such as scratches or abrasions. The wear and tear of this mould parts is caused by lack of lubrication.If the trace is just emerging, you can extend its life by adding a lubricant to the guide and guide.If the wear is serious, new parts should be replaced.Otherwise, the cavity and core may not fit well, resulting in a thin thickness of the part cavity wall.
- Put a marker on the conspicuous place to remind the operator not to “clean” the hot mouth of the gate
If the operator happens to see a small piece of stainless steel at the nozzle of the mold, it could be a point nozzle.Cleaning up something that seems to be a hindrance can often ruin a hot bill.Not to destroy the hot mouth, please before taking action, confirm the mouth type of hot runner system, and ensure that all operators are trained, can identify themselves are exposed to different types of tongue.
- The resistance value of the interaction check heater
You should have measured its resistance when you first started using a heater, and at the end of the year it’s time to measure it again and compare it.If the resistance has a floating rate of plus or minus 10%, it should be considered to replace the heater to ensure that it does not fail at the critical moment of the production process.If the initial resistance is never measured, measure once and use the value as reference data for future inspection of the heater.
- Sliding check
The work should be done once a week for the machinery that runs throughout the year.The end of the year is a good time to have a regular lubrication of the parts.
- Clean the thimble recommended for cleaning with mold cleaning agent every 6 to 12 months
After cleaning, apply a layer of lubricant to the thimble to prevent abrasions or ruptures.
