Electroplated Counter Block Of Molins Cigarette Filter Engaging Machine Mk8 Max 3

Blackened Rolling Block is a casting part of filter assembly machine, placed next to the rolling drum, functioning together to roll the tipping paper and connect the filter and the cigarette.

1. Advantages Of Blackening

Blackening can be done in large batches (ideal for small parts).

There is no significant dimensional impact (the blacking process creates a layer about a micrometre thick).

It is far cheaper than similar corrosion protection systems, such as paint and electroplating.

1. Black Oxide Specs

The oldest and most widely used specification for hot black oxide is MIL-DTL-13924, which covers four classes of processes for different substrates. Alternate specifications include AMS 2485, ASTM D769, and ISO 11408.

This is the process used to blacken wire ropes for theatrical applications and flying effects.

1. Mid-Temperature Black Oxide

Like hot black oxide, mid-temperature black oxide converts the surface of the metal to magnetite (Fe3O4). Yet mid-temperature black oxide blackens at a temperature of 220–245 °F (104–118 °C), significantly less than hot black oxide. This is advantageous because it is below the solution's boiling point, meaning there are no caustic fumes produced.

Since mid-temperature black oxide is most comparable to hot black oxide, it also can meet the military specification MIL-DTL-13924, as well as AMS 2485.
