TPE products, temperature control issues can arise
Time of issue:2023-11-10
When customers use injection molding machines to produce TPE products, temperature control issues can arise. We at Sibo Wang Manufacturer have summarized some tips to troubleshoot these problems:
Common reasons for high temperatures include:
* Insufficient oil tank volume and cooling capacity
* Quantitative pump system sized based on rapid feed speeds, excess flow returns through high-pressure relief valve and generates heat
* Faulty unloading circuit or no unloading circuit, resulting in continuous high pressure overflow and heating when idle
* Narrow, lengthy, or excessively curved hydraulic circuits creating large local and linear pressure losses
* Low component precision and quality assembly, causing significant mechanical friction loss
* Incorrect fit clearance, either too small or excessive wear, leading to high internal and external leakage and decreased volumetric efficiency
* Excessive operating pressure set higher than needed, possibly due to tight seals or increased seal leakage
* Higher ambient or operational temperatures causing increased oil temperature
* Inappropriate viscosity selection, both too high or too low can cause overheating
To address these issues, we recommend:
* Adjusting the pressure relief valve regularly based on load requirements
* Selecting appropriate hydraulic fluid and adjusting viscosity where possible to reduce viscous friction
* Improving lubrication conditions of moving parts to decrease mechanical friction and generate less heat
* Increasing component and system accuracy, controlling fitting clearances, reducing start-up forces, and adding cooling systems
