Hello all,
I've been tasked with documenting/replacing an ancient piece of hardware that was used for a few decades in my employer's factory.
The equipment is a simple U-shaped heating element/bracket duo that from what I can tell is purely resistive.
The bracket itself is some type of highly corroded steel which provided a low thermal impedance path from the heating element to our thermoplastic extruder's crosshead. The heating element itself seems to be encased in a ceramic-type material or epoxy. There are only (2) terminals across the element. The power rating is 700W.
I have (2) questions:
1. Does anybody know of a reliable manufacturer for thermoplastic extruder hardware/heating elements? If you have any experience or tips on how to locate manufacturers, I would also appreciate the advice.
2. The terminals on one of these elements is corroded to the point where I can't obtain a good resistance measurement with my DMM. Should I use some type of chemical rust penetrator? What's your M.O. for getting better contact?
I appreciate any advice you have to offer.
Thanks in advance!
