First of all, I have to assume that this rust and scale is primarily in the water passages and is related to the mold cooling process. However, let's get a few other possibilities out of the way first.
Mold space dehumidification is something to consider of course. Placing or utilizing a mold space enclosure and dehumidifying unit at the press is always a good idea.
Also, if the mold is rusting and scaling during storage you may want to consider a mold storage room/plant dehumification system. Another possibility is a dehumification room where wet molds can be quickly dried after use - before being stored.
But to the most likely problem. Chemical treatment and filtration (straining) is commonly used for this issue. Many people run glycol in their lines to help prevent contamination and corrosion. An in-process filter strainer should always be used as well.
I'm not an expert in any of these areas, but I'm sure someone at Conair can help you through this...please feel free to call me if you like at 724-584-5507 and I can get you in touch with someone who can really help.
