1. Maintain the mold and clamping system.
-
Moldless machine: Clean the jaw surface thoroughly and apply anti-rust oil to protect the metal surface.
-
The machine is currently clamped: Clean the mold and perform mold closing at low pressure (do not use high pressure). This helps avoid jamming of the clamps or difficulty in opening the mold after a long period of inactivity.
2. Clean the puller barrel and screw shaft.
-
Cleaning the plastic: Use PP or PS plastic scraper to clean the barrel, pushing out any remaining raw materials or flammable plastic inside.
-
Screw position: After cleaning, move the screw back to its maximum position . This helps prevent any remaining plastic from burning during the next heating cycle.
-
Cooling system: Close the coolant valve on the puller barrel and use an air hose to clean out any accumulated water.
3. General cleaning and cleaning of electrical cabinets.
-
Cleaning the machine body: Wipe away any dust, dirt, and grease adhering to the machine body.
-
Safe cleaning of electrical cabinets:
-
Turn off the power and wait 15 minutes before opening the electrical cabinet to ensure that the electronic components have discharged completely, thus ensuring the safety of the circuit.
-
Use a dry cloth to wipe away dust and use an air blower to remove dust from hard-to-reach areas.
-
Moisture and insect protection: Place additional desiccant bags and seal the electrical cabinet tightly to prevent component oxidation or damage to wiring caused by rodents.

4. Conclusion
-
After completing the above steps, proceed to turn off the main circuit breaker (CB) of the machine to completely cut off the power.
Following this procedure correctly will help keep the machine in optimal condition and ready to resume operation whenever needed.
