Insufficient equipment maintenance during low density polyethylene low density polyethylene processing
Problem Phenomenon
Frequent equipment failures, product quality fluctuation, low production efficiency.
Insufficient maintenance causes decreased equipment accuracy, worsened plasticizing quality, and increased energy consumption.
Cause Analysis
(1) Equipment running long-term without periodic maintenance
(2) Screw and barrel wear not checked and replaced in time
(3) Mold not regularly maintained and polished
(4) Sensors and instruments not regularly calibrated
(5) Lubricating oil not replaced on time, mechanical parts worn
Solution
(1) Establish an equipment preventive maintenance plan, monthly, quarterly, annual maintenance
(2) Regularly check screw clearance (not exceeding 0.2mm) and barrel wear
(3) Perform maintenance and polishing on the mold every 100,000 shots
(4) Calibrate temperature sensors and pressure sensors quarterly
(5) Establish equipment archives, record maintenance and repair history
Key Takeaway
Equipment maintenance is the foundation of stable production; a standardized periodic maintenance system and recording system needs to be established.
