Insufficient equipment maintenance in heat-resistant polyethylene heat-resistant polyethylene processing
Problem Phenomenon
Equipment failures occur frequently, product quality fluctuates, and production efficiency is low.
Insufficient maintenance leads to decreased equipment accuracy, worse plasticizing quality and increased energy consumption.
Cause Analysis
(1) Equipment running long-term without periodic maintenance
(2) Screw and barrel wear not inspected 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 and annual maintenance
(2) Regularly check screw gap (not exceeding 0.2mm) and barrel wear
(3) Maintain and polish the mold every 100,000 cycles
(4) Calibrate temperature sensors and pressure sensors quarterly
(5) Establish equipment files, record maintenance and repair history
Key Takeaway
Equipment maintenance is the basis of stable production, and a standardized regular maintenance system and record system needs to be established.
