[QUOTE="Patrick Coon, post: 179580, member: 11366"] Hi Ela, Here is a chart with the Press Parameters for our older furnaces. If a person has an older furnace (ex: ProPress 100) I always suggest they start with the parameters for the EP500. If a newer generation furnace you should start with the EP600 parameters. Input these into your furnace and try a pressing. Once you have pressed and divested (no Invex yet) examine for reaction layer and complete pressing. If you have a complete pressing and minimal reaction layer leave it alone. If you have little reaction layer, but an incomplete pressing, raise the high temperature by 5C; repeat until you get a complete pressing. If you have a complete pressing, but heavy reaction layer, lower the temperature by 5C; repeat until you get an incomplete pressing then raise the temperature back to your last complete pressing temperature. If you are getting "ice cream scoop" shaped divots in the surface, this is a sign of an incomplete pressing and pressing temp should be adjusted. Of course this all assumes that your burnout furnace is calibrated correctly, your sprue and pattern placement is correct, etc. Also download the IPS e.max Press Monolithic Solutions Instructions for Use (IFU) from the IV website, so you have all the relevant information on sprueing and ring placement. Below is the direct link to IFU. I hope this helps and if you need any more guidance, please give me a call at 800-533-6825 ext 4200 and I'll be happy to help as I can.
