Thank you.
I've since been able to make a nice looking note for the cosmetic thread and attach a GTOL in it using this:
M&MAJOR_DIAMETER:att_feat[.0] x &PITCH:att_feat[.2] - &CLASS:att_feat
&g4
this creates a note like M24 X 2.00 - 6g
However, I'm not happy with cosmetic threads for a...
Hello,
In reference to the 14 year old thread: thread554-33861
Sadly this issue still exists. Does anyone know how to change the decimal places in the embedded note that is created with cosmetic threads? (my work-around solution at the moment is to create a UDF with a cosmetic thread and a...
Hello,
Does anyone know why LSR molders typically decompress the cold runner *after* the valve gates are closed?
I can understand this practice with open nozzles, but don't know why it's also done with valved ones.
Thanks,
Hello,
I've been recommended this book on the topic: Accelerated Testing and Validation by Alex Porter.
I'm wondering if anyone has any other suggestions they've found useful. I'd like to gain some [practical] knowledge in this field.
Thanks!
Thanks for the replies.
Actually it's not a practical question, that's why I omitted all the application details. What I'm after is the theoretical 'area' from the overall heat transfer equation q=U * Ar * LMTD. If it was a length of tube in shell, then I know that area is just the surface...
Hello, I realized this may sound like homework but it's not. I'm actually making this as a mock heat exchanger for a pair of servo motors. I was hoping to calculate if it will be sufficient to drill a couple of parallel NPT tapped channels in an aluminum block. I'm assuming for now this area is...
Hello,
What is the exchange area (from q=U * Ar * LMTD) between two identical parallel thru-holes drilled in a block? Is it pi*D*L*2 ?
Thanks and sorry for the basic question,
Thanks IRstuff, that got me the T difference of the coolant and chilled water, I must be very rusty in thermo to have missed that.
What do you think about having a simple on/off solenoid valve on the water side for temperature control?
Hello all,
Kindly point me in the right direction:
I'm hoping to design a low cost closed loop cooling circuit for our servo motors. I Would like to have tower/chiller water running through helical coiled tubing in my coolant reservoir tank to act as a heat exchanger. Since I dont know the...
Thank you compositepro
I think youre right about the trial and error, the analytical approach does exist but i know what those calculation will tell me 'your feed port is 10x too small' however i can't increase much. what do you think about starve feeding and injection machine (as opposed to...
Hello
I hope im in the right forum.
Would like your tips and ideas as I'm having great difficulty feeding TPE resin into the auxiliary injection machine.
the material is Versaflex OM1245 in 3.5mm pillow shaped pellets. the machines have screws from 16-25mm and a the largest feed port is an...
