Hey guys I recently bought a Jacob's injection press and can’t seem to get the set up how I want. I been playing around with the temperature and pressure, trying to fine dial it in. At first I was getting dents in the cavity and next I was getting flash around the cavity. Is there any correlation between temperature and pressure with dents and flash? Well of course there is but it seems like I'm not make the connection 100%. I had the heat at 3.5 and the pressure at 22 psi, which gave me the best results but not perfect results.... Any help? What causes flash, temperature or pressure, and what causes dents pressure or temperature?
