Nitriding

In what applications would nitrding surface treatment be used?

Nitriding is useful for moving components in a mould.

Typical applications include rotating cores in cap moulds and sliders in moulds that make cups or jugs with handles.

Nitriding is a surface treatment which penetrates the skin of the steel and hardens the surface so that no damage will occurr between the contact surfaces due to lack of lubrication.

Nitrided surfaces do not require lubrication so mold maintenance is easier ( although a light film of grease applied to new moving components will make them easier to slide or rotate ).
