Lubrication is the single most important maintenance practice for WPC extrusion machines. Properly lubricated components reduce downtime, extend machine life by 20-30%, and ensure consistent product quality. Yongte engineer suggests the operators to following the instruction to do lubrication for WPC extrusion machine frequencyly.
Most critical component requiring regular attention:
Note: In high-temperature or dusty environments, reduce interval to 3,000-4,000 hours .
Key point: Screw bearings operate under extreme conditions (high heat, pressure, and vibration) - never skip lubrication .
1. Environmental Factors Affecting Lubrication Frequency:
-
High temperatures (>60°C): Reduce interval by 20-40%
-
Dusty/fibrous environment: Lubricate bearings every 200-500 hours
-
Heavy loads: Increase frequency by 30-50% or lubricate every 500-1,500 hours
2. Lubricant Selection for WPC:
-
Always use high-temperature-resistant lubricants (min. 180°C) due to machine heat
-
Choose anti-wear additives to combat abrasive wood fiber particles
-
Avoid petroleum-based products that might contaminate WPC material
-
Never over-lubricate: Excess grease traps dust and causes heat buildup
-
Clean before lubricating: Remove old grease and debris to prevent contamination
-
Document maintenance: Keep detailed records of lubrication dates, quantities, and types used
-
Follow manufacturer guidelines: Specific machine models may have unique requirements
