Insufficient Equipment Maintenance During Processing of High-Density Polyethylene High-Density Polyethylene
Fenómeno do problema
Equipment failures occur frequently, product quality fluctuates, and production efficiency is low.
Insufficient maintenance leads to decreased equipment precision, worse plasticization quality, and increased energy consumption.
Análise das causas
（1）The equipment has been running for a long time without maintenance according to the cycle
（2）The wear of the screw and barrel is not checked and replaced in time
（3）The mold is not regularly maintained and polished
（4）Sensors and instruments are not regularly calibrated
（5）The lubricating oil is not replaced on time, and mechanical parts wear
Solução
（1）Establish an equipment preventive maintenance plan, with monthly, quarterly, and annual maintenance
（2）Regularly check the screw gap (not exceeding 0.2mm) and barrel wear
（3）Perform maintenance and polishing on the mold every 100,000 molding cycles
（4）Calibrate the temperature sensors and pressure sensors every quarter
（5）Establish equipment archives to record the maintenance and repair history
Conclusão principal
Equipment maintenance is the basis of stable production, and a standardized regular maintenance system and record system need to be established.
