- Richard Burke replied to the topic 'Instrumnt for wire drawing lubricant concentration' in the forum.Keep in mind that the important thing you are looking for is lubricity. While your supplier may suggest levels of concentration that should work for you, there are simple tests that can also tell you how good the solution lubricates. They have ben discussed at length earlier in posting.
- Richard Burke replied to the topic 'conductor elongation tester standard specification' in the forum.24.9 cm is 99.6% of 25 cm. That is nearly negligible error in the big scope of things and should not be a problem.
- Windabillty is dependent upon many things including the coating on the wire, lubricant if any, the spool (size, shape, and design), winding tension, traversing rate and quality of traverse, and etc.
- Not that hard to find an answer.
Transition temperate is the temperature at which a solid material become plastic or fluid. The cut thru test is an example: you cross two wire on each other at 90 degree angles and place a weight on the intersection and then heat the samples in a test device. When the coating begins to reach it transition temperature, the weight on the wires pushes one wire into the other and as the coating continues to soften it thins until the two conductors touch.
Different materials have different transition temperatures and some might have two - low temperature enamels have a less complex chemical structure than higher temperature enamels.
Not sure where you are and what type access to data you have but this information was easily found on the internet.
- Richard Burke replied to the topic 'conductor elongation tester standard specification' in the forum.A quick simple test would be to run the tester until the elongation indicator displays a number that is approximately 5 cm. Read what is indicated as accurately as you can. Measure the physical distance of the items where you previously measured 24.9. Subtract the 24.9 from the measured distance. Divide that distance by 24.9. Does sit equal the number shown on the elongation indicator. If it does you really don't have a problem as you are getting a fairly accurate elongation measurement.
