Nick,

I just recently attended RJG Master Molding class and they also taught the 2/3 rule. A toggle press exerts more force on the outside corners of the B platen. A hydraulic press exerts more...

Rick,

Thanks for clarifying. I'll give your recommendations a try and post the results once I know. Might be a week or two before I have any results.

Rick,

I read your reply and believe I understand what you are saying, but just want to verify. When you say leave the barrel full are you implying exactly as that states? Or do you mean just run...

I need some suggestions here. I have a new mold that I've been working with and have a lot of problems with start up. I am experiencing a lot of white milky streaks throughout my part during start...

Also, do you agree with Brent that a worn screw shouldn't make it stall. This was just something my repair technician told me that he had seen in the past. Seems to me that if it was worn a little...

Rick,

What you are saying makes perfect sense. When it was "stalled" the only way I could get it to turn was to retract the screw way back and vacuum out the material in the feed throat. I will...

Brent,
