Production Process
Printing Polishing Magnesium Plate is produced by process semi-casting and hot rolling with tons rolling machine.
Semi-casting is through using vertical casting and is colded by constant temperature well water under around during casting processing. Making casting completedly slabs(billets) have very small grain and very tight spacing between grain and grain.
Ensuring perfect inner quality.This point can be verified that we used Inspection method for macrostructure of wrought magnesium alloy products.
We produce printing polishing plate conforms to MIL-T-38749(USAF) Standard.
Normal mention to Magnesium Tooling Plate is pointed magnesium alloy hot rolling platewhich is through heating treament state H24, H26,O.
So Magnesium Alloy Plate ia also called AZ31B H24 magnesium alloy plate.
Have a perfect flatness and good surface with moderate strength and ductility.
