Solenoid problem?

Hello All, I have an old Vinyl cutter that can cut rubber using a 24v
cont duty cycle solenoid. My question is: Can the solenoid degrade
after 10 years and thousands of cycles to not generate the downforce
needed to cut the thicker material? I have verified the correct
voltage to the solenoid when activated and isolated the solenoid by
using a seperate 24V pwr supply. Either way it does not quite have the
downforce to get thru the material. So that led me to looking at the
linkage from the plunger to the blade holder. I lubricated and have
tried many adjustments in the linkage. The solenoid is about $65 when ordered and don't know if buying the replacement will do the trick. I was really wondering if the solenoid can still activate but lose some of the downforce over the years..... Any help would be great... Thanks in advance Greg R Rich Grise Jan 1, 1970 0 Greg said: Hello All, I have an old Vinyl cutter that can cut rubber using a 24v cont duty cycle solenoid.

A solenoid doesn't deteriorate, electrically. It will wear mechanically,
however, and gunk from the air could gum it up. But ampere-turns are
ampere-turns, I'd think.

Are you really losing downforce, or do you just have dull blades?

Good Luck!

ISTM that a solenoid (yoke or plunger - I think the plunger would
foul thinks up worse) could become magnetized like a relay armature
and that might cause it to weaken like a relay (which will fail)

I would be checking the blades !!
