Melt Flow Index (MFI) Tester is an important piece of equipment used to measure the flow properties of thermoplastics. Like any testing equipment, it requires proper maintenance and occasional troubleshooting to ensure that it operates accurately and reliably. Here are some troubleshooting and maintenance tips for MFI testers:
1. Regular Cleaning:
Regular cleaning is essential to keep the MFI tester in good working condition. Clean the barrel, die, and piston regularly, as well as the heating elements and the cooling system.
