Summary for teflon coating of metal Discussion
Teflon coating of metal is discussed as a way to make a small, strong, very non-reactive barrier piece for pushing a coating across water. Doug Martin wanted a 1/4-inch by 2-3 inch rod with at least 0.040-inch PTFE thickness, stronger than solid PTFE and more durable than ordinary pan coating. The thread’s only visible answer, from the archive meta description, suggests shrink wrap tubing as a cheap possibility, but that is not the same as a thick bonded PTFE coating and may not meet the strength or thickness requirement. Based on the question, the real need is for a robust, easy-to-clean, chemically inert surface over a metal core, but the excerpt does not show a definitive process recommendation or confirmation that thick PTFE can be applied directly to metal in that form.
Q. I need to create a small teflon rod about 1/4″ dia. by 2-3″ long which is stronger than a pure piece of PTFE of that size. Thus, I’m looking for information on how to coat a metal piece (any kind of metal) with teflon resin. I don’t want the pan coating – it comes off too easily. I would like to coat it at least 0.040″ or deeper! The use for this piece is as a barrier to push a coating across a water surface; a barrier which needs to be extremely non-reactive, strong and easy to clean. (teflon!) Thanks, Doug

 | A. Try shrink teflon tubing. If that is not thick enough, try two layers. This takes a bit of luck and a bit of skill. If you can stand thicker wall, like 1/16″, Regular teflon tubing will work. Warm it in boiling water and freeze your pin on dry ice. Shove fast. Will give a very snug fit. James Watts A. Talk to engineers at General Magnaplate [Linden, NJ] and see if they can help you.

RFQ: Looking to have several magnesium parts chrome plated, or Dow 7 finish. Plating is preferred. Is there any one in Ontario, New York, Ohio or Michigan capable of doing this? I have several contacts for California, but I would like to find a local contact for this job… Thank you;

Ed. note: This RFQ is outdated, but technical replies are welcome, and readers are encouraged to post their own RFQs. But no public commercial suggestions please ( huh? why?).
A. Mr. Martin’s inquiry got a couple of good responses, to which I’ll only add this: many people apparently don’t realize that metal finishing is a very strongly ‘job shop’ oriented business. That is to say that you don’t need to personally develop a teflon coating procedure in order to get a teflon coated rod. You just find a coating shop, send them your rods, and they come back teflon coated. Marty Broeders, you might want to try Luke Engineering & Mfg. Co., Inc [a finishing.com supporting advertiser]

A. Mr Douglas, You can ask Dupont for the nearest Dupont LIA (Licensed Industrial Applicator)for Teflon coatings. All of them are great professionals that can help you.
