[Working principle]: Under the action of external force (pressing by hand or rubber hammer), the alloy steel wheel after high frequency quenching and heat treatment will engrave letters or numbers with a certain depth ( 0.1 ~ 0.3 mm deep) on the metal plate.
^^ [Features]: The heat-treated steel wheel can be rotated to the required letters or numbers, and the typeface can be easily changed; the word spacing can be adjusted manually; different character heights can be realized by replacing the wheel.
^^ [40 characters]: One
wheel includes 40 characters: 10 numbers, 26 uppercase letters, 4
common symbols(Note: no lowercase letters). ^^ [Size of the wheel]: No
2 wheel: Fonts height 2mm Fonts width 1 mm; No.
2.5 wheel: Fonts height 2.5 mm Fonts width 1.25 mm; No.
3 wheel: Fonts height 3mm Fonts width 1.5 mm; No.
4 wheel: Fonts height 4mm Fonts width 2 mm; No.
5 wheel: Fonts height 5mm Fonts width 2.5 mm; No.
6 wheel: Fonts height 6mm Fonts width 2.8 mm ^^ [Application]: Changed parameters printed on the metal plate: such as specific model, date, batch number, serial number, serial number, etc.
