So I am doing a solidworks simulation on a copper tube with brazed flat endcaps. I applied an internal pressure of 350 psi, and an internal and external temperature of about 80 degrees C. The tubing is 1"OD X .05" Wall, and for the simulation the length is 11". The yield strength of the copper...
So I have seen a few types of finishes on galvanized sheet metal on the internet. The typical patterned kind of metal chip looking finish and what looks like a more smooth, almost stainless steel looking galvanized. I want to use the smoother style galvanized sheet, but I am not sure what to...
So I am designing a check valve for a triclamp, and was looking at designing something pretty much just like the pic except without the o-ring as the triclamp has a gasket. My question is how they make the swing plate? Is it two pieces, a pin and a plate welded, or is this one stamped part and...
so I am welding a triclamp fitting onto a pipe. Now I was wondering, is it standard practice to fillet the edge of the pipe for welding the flat face of the ferrule? I guess in general when you weld pipe would you chamfer the edges around like this normally to do a bevel...
I am assuming from this that this is a standard size pipe of some sort, and then it is machined and then bent??I am trying to make this in a 1/4" hose barb, what size stock would I use I cant seem to find a pipe that works for the inner and outer barb dimensions of arounf .119" id and around...
Just wondering if this is a difficult part to machine. It is a standard triclamp 1" fitting, but I am trying to design a swing type check valve feature into it, so I am machining in a roughly 2mm dia cut to house a dowel pin of some sort attached to a flap if that makes sense...
So I am designing a manifold, and I know there are multiple ways to weld a barb to a pipe, however the barb needs to be on a 30-45 degree angle (undecided) so reduce pressure drop, now, I will machine the barb, but would it be best to just drop the barb into an angled hole in the pipe? or cut a...
I am getting this made in China and they want to save cost and make two parts and welld them. it would be made from brass and fastneed with silver solder, they want to know the breaking force required to pass, and I am not sure of a reasonable force to spec. The part itself is screwed onto the...
Ok so i have a plate, 6061-t6 aluminum about 1/4 thick, it is machined, and you can see in the model, there are paths about 1mm deep that are different colors. I want to achieve a cool blue polished look on the valleys you can see in the image, and a metallic chrome look on the center line in...
How would they machine a socket driver? When I look at a socket on the back side the square socket side, the angles are very sharp with maybe a very slight radius, whats the standard procedure to machine this? I see some radius on these look to be less than 2mm even, how can they get that deep...
I am not sure what pump to use. I need a pump for continuous use, that can handle around 10-20m head pressure, and around 70l/min. The problem is that I have round maybe 6-7" overall height and around maybe 10" for length overall. I am using an RD-40X pump now but with the pressure drop in a few...
I did an analysis in solidworks and it said a few features are inaccessible, I am assuming it is saying that because of the radius in these grooves. This part will eventually be cast, but for a quick turnaround for proto we want to machine them. Aluminum, plates, overall length of the part is...
Ok so most of the time you would put a self clinching nut standoff into sheet metal and usually you are given a min sheet metal thickness to use. In my Case I am putting it into a block of copper. Most sheet metal min thickness for these is around 1.4mm, however I do not see a max thickness. My...
ok so this is a small part for a little pump. It is an iron sleeve with about 5.5mm outer dia. it's very similar to an iron bearing sleeve, but I was wondering if its possible to manufacture one with an endcap on it. The surface finish etc must be quite smooth along with the dimensional...
just curious it it possible to fillet around a part like this by machining it, and if so how? Or too costly? the piece is CDA110 copper pretty strong copper, and about 1.5x1.5 inches,.,http://files.engineering.com/getfile.aspx?folder=e0b6ec96-6f1e-4e7b-b65c-d40040737bd8&file=AAA.PNG
I have the arm from an eliptical. it has a thin crack starting on the upper arm (see attached). I was thinking of mig welding this? would that make sense? do I have to prep the surface at all? or pretty straight forward weld down the cracked area over the painted surface? the metal plate is...
I have some tubing I want to insert into some mechanical aluminum tubing,cap the ends and add barbs to create a radiator which will hold glycol/water mix for cooling. Here are a couple questions.
1. I am using 6061 Aluminum,is this the best aluminum grade to use in this case?
2. Is it...

I have a plate that I want machined that will have fins on both sides. A lid will then be on either side, and sealed from leaking wit an o-ring around the fins. In order to do this I need a really tight tolerance on the flatness. The part would be about 5mm thick once cnc'd, and the dimensions...
I am looking for notes on flushing. I designed a stainless steel manifold out of square mechanical tubing as seen in the attached pic. No my question is what note should I put in the drawing to ensure the assembly is flushed with clean water. I am not sure how to put it in technical terms. I...
