Direct Part Marking
Print machine and human readable text on almost any substrate. Print alphanumeric text, 1D barcodes and 2D codes for part identification and tracking through the production process and supply chain.
Direct Part Marking with Continuous Inkjet
While there are a number of print and etching technologies available, the majority of the direct part marking projects that we work on are for continuous inkjet. With continuous inkjet printing, you can print directly on almost any substrate – even where the surface is curved or uneven. You can also print in a selection of opaque colours for maximum contrast.
UV curable inks and fuel-resistant inks can be used for parts and components that are subject to exposure to chemicals. There are also inks available for surface-treated metal.
- Print a combination of machine and human readable data
- Variety of black and opaque coloured inks
- Multiple connectivity options for integration with production equipment
- Print high quality linear bar codes and 2D datamatrix codes for part traceability
- Wide range of process-specific inks available (including UV flourescing; fuel resistant; wash-off)
Printing Machine Readable Part Codes
Electronically generated codes let you print part-specific information in a simple format for reliable verification and part traceability. These can be in a 1D linear bar code or 2D data matrix code.
Manufacturers are increasingly using 2D data matrix codes because of the ability to encode a larger amount of data. It is also a more robust coding format; datamatrix codes are readable in any orientation and there is no risk of misreading.
Customer Application - Marking Compressor Impellers
A UK manufacturer of automotive and aerospace components uses an alphaJET continuous inkjet (CIJ) to mark compressor impellers. The company prints 2D codes and alphanumeric text on machined aluminium and titanium parts. These include production location, batch and part number.
The codes are printed to the customer’s rigorous requirements, using MEK-free ink. A camera checks that the 2D code complies and that it contains the correct data.
