Works reasonably well

I did try a simulation in ANSYS. To find out the volume, I modeled the bag as an open shell and applied pressure on the inner sides. Then exported the deformed shape as STL file, capped the opening to get a volume in Solidworks.

Thank you all for the comments. Measuring the volume is not a problem. I've made a template, cut out the shape and sealed the edges. I was just wondering if there was a faster method (I really don't have time to understand the math behind it) to generate shapes given a volume as input. So far...

How would I calculate the maximum possible inflated volume of an initially flat sealed bag which has an irregular shape (two examples below) made out of two pieces of material which can bend but not stretch and assuming the opening is on the top edge? For a rectangular shape, this is commonly...

Actually 45 is the shore A hardness

The gasket material was identified as Natural Rubber 45

What adhesive would you recommend for bonding TPU to a PVC substrate? Preferably a heat-activated adhesive that is non-tacky at room temperature. Medical grade would be a plus, but not absolutely necessary. Any input is appreciated. Thanks

This is a custom part taken out from a commercial medical device, not from a supplier's catalogue. It is very thin and stretchy, almost like a rubber latex glove but pretty sure it's not. I was told it could be Santoprene (TPV), but not knowing that material I can't tell for sure.

I'd like to know the exact material of this gasket. What's the best way to find out?

Path dimensions did the trick, just had to split the entities in two to be able to create the paths: Thanks!

In SW 2017 there is no option to set an equal length relation between the projected curve and the sketch arc.

I actually built a mold, with cavity split in half and a core. Problem is material didn't cure after closing the mold: I was looking for alternative techniques, and in fact I considered dip molding. But the pot life is really short and I don't want to waste material for the bath. Will try...

What is a simple way to apply a uniform coating of rubber (thickness 0.15-0.35 mm) to a mandrel? The mandrel is essentially a cylindrical shape and made of aluminium. The coating is a urethane rubber: https://www.smooth-on.com/products/simpact-60a/

Tried many times but found it impossible to get convergence using static structural for more than 30° rotation. Eventually, I could get to twist 165° using Explicit Dynamics with damping control to remove unwanted dynamic effects.

What are some practical applications of Graphene in the healthcare industry? Please feel free to comment if you have any useful insights

Right now I'm prototyping with Latex finger cots, which is the closest thing I could find. Since this is for use in a medical device, Latex material cannot be used. The final product will probably be injection molded or dip molded. LSR could be a good option but for my application I think...

I'm looking for a material similar to Natural Rubber Latex, that can be poured in a mold and cure at room temperature. The part to be molded is a very thin cylindrical membrane that is than twisted in its final shape. See picture below of the shape as molded. Dimensions are in mm. Any...

Hi All, I just stumbled upon this particular case where I want to set the length of a sketch curve (spline, arc, etc.) equal that of a edge (also spline, arc, etc.) in the model, marked in yellow here. The two entities should be parametrically linked. I could not find a straightforward...

What if I want to take this even further and go a full half rotation (180°). Is there any chance it will converge?

Thanks guys, this really helped!
