Greetings,
I am trying to successfully inject a mold I made for a card, but I keep getting short shots. Here is a picture of the mold and the short shot:
I am concerned that I'm not designing the mold properly, as I'm completely self-taught. I have successfully made several other molds; however, this was the largest and thinnest I have attempted. I did some research online and found a card mold with a fan gate, so I based it off of that.
I am using an LNS 150A (a benchtop, hand operated injection machine), and the material is ABS with a melt mass-flow rate nominal value of 21g/10 min .
Part Size: 3" x 2" x .03"
Vent Depth: .002"
Fan Gate Depth: 0.0225"
Runner Width: .25"
I realize this part is difficult to inject largely due to it being very wide and thin, along with material's viscosity.
Any advice would be appreciated!
