Hi All,

We are having difficulties removing endcaps and barrels on our molding machines. I haven't been able to find a best practice for this task so I wanted to ask the forum! We apply anti-seize prior to installation and torque to the manufacturer specs for both the endcap and barrel. Some of our injection units have probably been running for about 3 to 4 years without being disassembled and these are typically the ones we have the most trouble with.

Is it best to perform the removal while the injection unit still has the heats on? I am considering purchasing an impact wrench for just the removal portion and replacing the cap screws with new ones when re-installing with a torque wrench. The endcap cap screws are M20 and the barrel cap screws are M24.

We are looking to create a yearly TPM program of injection unit wear measurements and inspections, however with the lack of proper tools and amount of time required to perform this job this TPM program is just a dream for now.

Thanks guys!
