    complex sheet metal formed part/stamping

    dhengr: I have made some, and that's exactly what I did. I got most of it with a hydraulic press and wood tooling, and the rest with a torch and manual bending. The fact that I could do it with the press was promising, and think I can get it all that way with a properly designed tool, but at...

    complex sheet metal formed part/stamping

    It's just mild steel (not spring), but 3D printing isn't really in scope. Casting likely isn't either.

    complex sheet metal formed part/stamping

    Hi, I am a small time furniture manufacturer and am looking to make a design in low quantities formed from 5/16" steel plate. It has complex curves on it, and I hope to form it in a hydraulic press. I have had some success already but have been having troubles designing the dies to use. I can't...

    Pressure sensitive adhesive pad

    interesting. that's a good start. I definitely hadn't thought of including "cove" before.

    Pressure sensitive adhesive pad

    yeah, now that you mention that I've seen them too. Yet I can't find any available off the shelf. Not sure of those were just tooled up by the companies that use them on their products.

    Pressure sensitive adhesive pad

    Hi, I have a design for a floor display that is made of a bent 1" tube in a 12" diameter that sits on the floor. I am trying to find a foot pad for this and would like to avoid drilling into the bottom. Does anyone know of an off the shelf rubber or felt pad that has a negative cylindrical...

    injection molded part question

    Pud, your rule of thumb for blades is that the length must be 3x - 5x the thickness of the blade? I may be able to shorten it significantly and have it still function.

    injection molded part question

    Thanks for the tips. I'm going to have to think about this more, there has be a a creative way to avoid the slot being the way it is. Pud, your idea about the internal ribs might work, but something has to slide in there from the side without getting hung up during use, so I'll have to test it.

    injection molded part question

    I was worried about that too, Pud. Would it be better for that blade to come from the left side of the picture and shut off on the round portion on the right? That way it could be a separate easier to replace piece. Or would it be better in the long run to make a side action to keep the...

    injection molded part question

    Thanks for your response. No, it's not clear, and I could live with scratches, since they won't be visible in such a tight slot. As long as the dimensional integrity isn't compromised (even deep scratches wouldn't hurt) it would be good. Would the slot be pulled from the right side of the view...

    injection molded part question

    Also, FYI, this part is still early in the design and I realize it doesn't have uniform wall thicknesses, etc. I haven't been able to core out some heavy areas since I don't know which direction to to that in

    injection molded part question

    Hi, I am designing an injection molded part that has a couple tricky areas. All the areas shown in green below can have no draft. All the other surfaces can have 2 degrees or more. Currently I am envision the mold opening and closing as the two arrows indicate in the first isometric view. The...
