New pelletizer die design eliminates freeze
The newly developed underwater pelletizing dies from Crown Machine (stand 10.1 / D31 at Chinaplas 2009) eliminates die-hole freeze off. The machine’s die incorporates 15% patented additives, boron, and ceramic in a medium-grain tungsten carbide material. The die allows melt up to about 329 degrees C to flow through the die holes, and cold water to contact the cutting surface without die-hole freeze off. The melt leaves the die holes and enters the cutting chamber without encountering turbulence or random blade contact.
