Various marking options
The Voortman V304 can be equipped with different marking technologies. Based on requirements such as:
- Allowed heat distortion
- Required marking speed
- Required number of characters and data size
- Depth of marking, based on post processes
- Technology or marking costs
Inkjet marking leaves a mark with absolutely no heat distortion. Marking speeds are up 20 m/min which makes it the fastest marking option available. Inkjet marking is mostly used for large data sizes and a high amount of characters. Marking consumable costs are also negligible. However, marking is temporary and is not visible after shot blasting, galvanizing and painting.
The Voortman V304 can be equipped with an inkjet marking unit which can print all types of lines, texts and layout marks onto a plate. It is designed to operate with the greatest accuracy, even at the high speed of 20 m/min.
The inkjet marking unit is equipped with a 16 nozzle, stepless rotatable printing head, which can rotate 360°. This enables printing of texts in all directions. Also the text height can easily be regulated between 3 mm and 67 mm by rotation of the printing head. The dot size can be adjusted on the control unit, to the desired value. (Video Inkjet marking)
Marking by plasma creates a surface discoloration and vaporizes a small amount of material. For plasma marking, the plasma unit will automatically switch to Argon gas for optimal layout marking results. The marking amperage and speed can be increased and decreased to adjust the visibility. With increased amperage the marking will be visible after shot blasting, galvanizing and painting. Marking speeds depend on the depth of the mark but are up to 7,5 m/min (24-1/2 ft/min) and is normally meant for leaving marks of 0.4 millimeters deep.
Performance Scribe by plasma creates deeper marks than marking by plasma because Performance Scribe is done with compressed air or nitrogen. Besides leaving a deeper mark other advantages of Performance Scribe are that considerably less consumable wear occurs and since you don’t use Argon gas, no gas change and gas supply will be necessary.
The advantage of plasma marking and Performance Scribe is that it can be done with the same plasma unit.
