MPI MELT PRESSURE engineers can design and manufacture almost any Extruder Rupture Disks design in quantities from 1 to 1000pcs. For any non-standard body design, please fill out and send back the PDF specification sheet.
Extruder Rupture Disks installation is very critical. They must be installed flush on the inner barrel of the extruder.
Extruder Rupture Disks are effected by temperature. Below is a table of how to change ratings of Extruder Rupture Disks based on temperature. All MPI burst discs have Inconel diaphragms, so are not greatly temperature dependant.
