    IcePak - Pressure Drop and Fan Operating Point

    Thanks for your reply hendersdc. Yes, I understand that the fan will operate at its operating point base on the pressures induced by the system, but how to I plot that figure? How do I say, ?the simulation results show that the fan is operating at XX CFM and XX InH2O?

    IcePak - Pressure Drop and Fan Operating Point

    Good Day, I was wondering if there were any icepak user here that could help. Is it possible (and how do you do it) to give the pressure drop of a system (An electronics enclosure containing a heatsink, heat sources, grill inlet and exhaust fan for example), and also to give the operating...

    Stamping Copper

    Thank you for all the replies, much appreciated. It will be approx 2000 HOLES per week I do drill them at the moment, but drilling leaves a large burr on the drill out side, which them involves a separate process to deburr. In terms of quality, pretty low quality in all honesty, a shear burr...

    Stamping Copper

    Thanks DVD I would certainly like a press brake setup, but I don't have the facility to place such a large machine unfortunately, and I only have access to 240v I would be punching in the region of 2000 holes per week

    Stamping Copper

    Hi Chris, Appreciate the reply. If you get chance to see the make and model of the machine please let me know

    Stamping Copper

    Thanks for the link So using that, I need less than a tonne. Is that something that can be achieved pneumatically?

    Stamping Copper

    Sorry, that was a Typo, was meant to say "5mm Hole", so it's just a simple 5mm diameter hole to be punched out. I would say around 2000 holes per week.

    Stamping Copper

    Good Evening, I am looking to design and make a machining that can stamp out a 5mm hole in 3mm think copper. I was wondering how I would go about calculating the force needed to do this. Also, does anyone think that this would be possible pneumatically with an air piston running off an air...

    Drawing Template - Back ground image sent back

    Hi, Does anyone know if its possible to add an image to a drawing template that would appear behind any other objects (Drawing views, tables, etc). For example, if you want a large company branded image in the upper right corner as a drawing background, then as you place your vesision table in...

    Part Numbering after a surface finish

    Hello All, I was wondering how you all manage your part number if you potentially have a product sitting on a shelf unplated, and the same product plated. Do you have a serperate part number for the unplated one. Send it out for plating, then book it back in as a different part number?

    Force Requirements

    Hi, This is kind of what I want to do Link

    Force Requirements

    Evening All, I'm after some guidance on how I calculate the force required to bend a piece of aluminium. Basically, I want do design a device that will bend a 1mm thick piece of aluminium, about 500mm wide in to a U channel shape. I plan to use tool which is a U channel shape die, and a form...

    Heat Transfer with Solar Loading

    Hi, Correct, there is about 0.4 Degrees C difference But, when I look at the value of stationary, we get 180C with Solar Load, and 165C with out solar load, so that's a DT of 15C. Then, at 70mph, we get results of 150C with Solar Load, and 149.6C with out solar load. Would it not be in the...

    Heat Transfer with Solar Loading

    Kind of makes sense, but would it create that much heat Also, when I compare both 70mph results (with an with out loading), there is no difference 70 Mph with Solar Loading = 150C 70 Mph without Solar Loading = 150C 0 Mph with Solar Loading = 180C 0 Mph without Solar Loading = 165C

    Heat Transfer with Solar Loading

    Good Day to All, I'm a bit puzzled by a phenomenon that I'm seeing during a set of CFD simulations. As an example, Say you have an enclosure with an internal heat source that is thermally connected to this enclosure. There is a solar load beating down on the enclosure. Simulation shows, when...
