Does anyone have any idea how one might anneal sterling silver, or knows someone in the LA area who does this? I've searched and called a bunch of companies, but haven't made any progress. Please advise.

Does anybody have any good techniques for inspecting some small, flimsy silicone gaskets on a horizontal optical comparator? The weight of the part deforms itself when 'stuck' on the glass vertically and we would like to find a way to avoid any deformation for a quick and precise inspection...

Thanks for the help guys. I was just checking out the ATA 300 spec and I came along a new DOT spec that not only has this 5 minute 1700°F requirement but also a heat endurance test: the container shall be exposed to 400°F for 3 hours and the surface of the contents shall not exceed 200°F. So...

I would like to get some suggestions on a material for a container for transport. I am no materials engineer, so some input would be greatly appreciated. The material doesn't necessarily have to be a polymer or plastic, it could be a metal or composite too. The main spec is that it has to...

The disc is flat and was stamped out of a strip. We have a testing block that we use to burst test the discs. I'm wondering what would happen if I only drop the thickness down to .004", and leave the hardness at 1/2 hard.

I could use some help on a safety disc I developing. I have a specified burst range that I need to meet and I am coming up high. The bore size is .295" and I am currently using .006" thick brass (70/30 CA260, 1/2 hard). The range is 2500-2775 and I am about 3150 w/o a burst. Does anyone have...

1. Yes, the fabric is directly in the center (no evidence of concavity) 2. Yes, we are sealing against an orifice. Since both sides are the same thickness, I am a little confused as to why it might favor one side over the other.

I was wondering if anyone had any ideas as to how/why a valve of ours would operate as it is: it is a dime-sized silicone valve with a dacron mesh sandwiched in the middle. To me, everything looks symmetrical. When this valve is inserted one way, it works perfectly, but when it’s inserted with...

Does anyone know what kind of procedures can be done to make a molded silicone part 'smoother'? We recently got some thin-wall diaphragms made and wanted to get a smooth surface similar to an OEM. The company had a procedure where they'd tumble the parts in talcum powder and then have them...

I had a question regarding passivation: hypothetically, if I was in a 'pickle' and did not want to send the stainless product to another shop to get passivation treatment, is there another equivalent method that can be performed in house? I know that pickling gets rid of all impurities on the...
