My idea is to have small series of parts, but anyway I need to inject them because is the cheapest way. The problem is, I intend to make the mold to locking with mechanical clamping, and also I intend to inject the PVC in about 4 minutes or so just to avoid using a big hydraulic pump (The mass of the PVC to be injected is about 4 kg). Since I don't have to make large series I can afford that waste of time. But if I want to make the pump and injection system simpler I need to mantain the mold heated to give the PVC time to fill it. Thats why I came with this approach, wich I'm now only evaluating. -- *Leonardo Marsaglia*. ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, SlashDot.org! http://sdm.link/slashdot _______________________________________________ Emc-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-users
