I'm looking for design information on vacuum sizer plates. I'm running a nylon profile and using a wafer type calibrator to control the extrusion in the vacuum tank. I'm not sure that I have enough plates or the correct spacing for my process. I'm getting close to a good profile but I feel that I may be missing some detail of the sizer design. Help, please IP: Logged |

I'm not the best person to answer this question, but since no one else has replied it will put in my 2 cents. It does not seem that there is a lot of information about calibrator design available. I'll trying to educate myself also. From what I know of nylon it would seem to be difficult to use calibrators to manage a pofile. Nylon has poor melt strength, oxidizes quickly, and then solidifies at a high temperature. Are you using a modified nylon? I have in my possesion Compuplast's Profile Cooling software which helps to design calibration. I would be willing to explore the application of the software to this problem with you, as long as the results could be posted here. Tom C IP: Logged |

Tom, the nylon that I'm running is Nylon 66 heat stablized. If you like, I can e-mail you a drawing of the design. IP: Logged |

Sure, send it. tomcun@ptd.net I'll give it a shot. I'm still kind of a novice at the cooling calibration stuff, so I can't promise much in terms of results. Tom C IP: Logged |
