First, I'll load some plastic pellets into the hopper and let them heat up for 6-8 minutes so it flows and injects better into the die
Once the plastic is warm, I'll clamp the die together and rotate the lever to push the pushrod that presses the plastic into the die
I have to make sure to keep pressure on the lever so the plastic continues to feed into the die even as the part cools and fills
Now that I have a finished sample, I can test it using a tensile test with this machine
I have to be careful to load the sample such that the clamps attach to the wider part of the dog bone shape so there is not a failure at the connection point
Once the test has been run and the data has been collected, I can see where the yield stress is for this material
Now if I ever need it, I'll know!
Back to the bridge...
What's wrong with the bridge?
One of the cables on the bridge is not secured correctly, if we don't do anything, the bridge will fall!
I know just the thing!
Based on the yield strength of this plastic part, it should be able to keep the cable from sliding out of its channel with a factor of safety of more than ten!
You did it Matman, you saved the bridge!
It was the least I could do, I'm just glad I could help in time!
All thanks to some engineering know-how and a little bit of preparation!
