Theory vs. Reality

Control of the Melting process depends on a number of factors including the proper screw and NRV design, and setting variables such as back pressure, barrel temperatures, screw speed and melt decompression. If we could eliminate the need for Melt Decompression which is used to eliminate drooling and stringing, the process becomes more stable and many surface imperfections become obsolete!
