Packing
As the magnets have strong attraction and we will use the spacer to apart the magnets each other in case people will be hurt when take it out. Then, they will be packed in a white box of pieces each, several boxes to a carton.Or according to your requirement to packing.
+By Air: If the goods will be shipped by air, all the magnetic should be degaussed and we will use Iron sheet to shield.
+By Sea: If the goods are will be shipped by sea, we will place a pallet on the bottom of cartons.
Tolerance
General tolerances:cutting surface+/-0.05- +/-0.2mm ground surface +/-0.01- +/-0.1mm
Sample
In general, SmCo samples were around 15 days, Alnico samples were 25 days, and Ndfeb was the same as SmCo samples.
