Does anyone have any experience with creating a hermetic seal on metal housings that are sandwiching a thin metal membrane? I'm told overloading will have its challenges since there will likely always be a fluid leak path between the metal and the plastic.
Hello,
We have a highly viscous paste emulsion that we are having a hard time keeping stable. We currently use a kitchen-aid mixer to mix it and we transfer it from the mixing bowl into a sheet of saran and then into a sealed jar. This isn't working since we need to open the jar to pull...
We have an oil in water emulsion, with a very low percentage of water (~7%) and a very high percentage of fine particles (~20 micron). It resembles a thick paste similar to cream cheese. We are using a small nozzle system to control the flow (which is very likely plug flow) of the paste to...
I'm working on a design for a device that infuses a slightly viscous material (~7cP) through 4 small nozzles. The nozzles will be embedded into tissue and will likely have different resistance to flow. In order to eliminate the possibility that all of the material will flow through the needle...
I have a 3 story home with an un conditioned third floor (with an insulated attic above that). I'm obviously losing a lot of heat to the third floor in the winter since all three floors are connected by stairs without any doors separating them. As a result the first two floors are never as...
I have a few lots of small parts that were meant to have been machined from grade 2 Ti. I have since learned that some amount of them are likely grade 5 (Ti6Al4V). They have already gone through part of the manufacturing process for 55 of them and they're too expensive to just throw out. Is...
Hello All,
I'm having a very difficult time with a resistance braze joint that I'm trying to create between grade 2 Ti and cp silver. I'm stuck with those two materials for a number of reasons so I'm hoping someone can offer some assistance. Here's the issue. I have two grade 2 Ti "shells"...
Has anyone had any luck with plating grade 2 titanium with pure silver (without nickel or any other materials)? I'm looking to improve my brazing process by pre-plating the surfaces with silver, but I'm not sure if it's possible or if the silver will actually be bound to the underlying...
I have a problem with a paste that I am attempting to extrude through a glass syringe. The paste is about the consistency of toothpaste and has very small (under 150 micron) particles suspended in it. When I attempt to apply a constant load to the teflon pusher of a glass syringe, I do not get...
