Typical Cases And Solutions Encountered When Injection Molding Machine Malfunctions?

Situation 1: The screw became stuck.
Fault manifestation: The screw is unable to rotate and the injection molding machine produces an odd noise.
Analysis of the fault: Investigation revealed that the screw was lodged in the barrel, most likely as a result of material solidification or foreign objects obstructing it.

Resolvent: 1. Turn off the power, stop the machine right away, and prevent further damage.
2. Disassemble the screw and material barrel, then remove any adhesive buildup or other objects from within.
3. Inspect for damage to the screw, barrel, bearings, and other parts, and fix them as necessary.
4. To keep the material from solidifying, modify the injection molding parameters, including temperature, pressure, and speed.
5. Put the screw back together and test it to make sure it spins smoothly.
Case 2: Damage from mold.
Fault manifestation: An examination showed that the mold was destroyed, and the injection-molded product has defects.
Fault Analysis: Inadequate cooling, improper operation, or a bad selection of mold materials could be the cause.
Resolvent: Turn off the machine right away to avoid production waste. After that, deconstruct the mold and look for the cause of the damage in the affected area.
3. Depending on the circumstances, choose better mold materials or modify the cooling system.
4. Educate operators on the proper use and upkeep of molds.
5. Run a trial mold after the mold has been repaired or replaced to make sure the final product satisfies the requirements.
Case 3: A malfunctioning servo motor.
Fault manifestation: Critical components cannot be driven, and the injection molding machine malfunctions.
Fault analysis: The servo motor is defective, according to an examination.
Resolution: Stop the machine right away and cut the power supply to avoid more motor damage. After that, take the motor out and check it for issues like damaged wiring or mechanical damage. Replace or fix the motor if necessary.
4. Verify the servo drive's functionality and perform parameter debugging. 5. To ensure that all performance indicators meet the requirements, reinstall the motor and test it.
