Aerospace Part Marking Ink & Machines

Meet Aerospace Standards with Inkjet Printing

For aerospace vehicles to operate successfully, all parts must seamlessly work together. Aerospace engineers ensure safety by subjecting parts to rigorous chemical, physical, and thermal testing. These tests help predict and reduce material/mechanical failure. Given the complexity of these parts, it’s important to know exactly where each component came from along the supply chain. 

The aerospace industry creates this traceability through various information standards and specifications. Systems like Spec 2000 and the Society of Automotive Engineers (SAE) AS9132 establish numbering schemes and readability standards that ensure each component can be traced back to its origin. 

To comply with these systems, companies need to use reliable marking methods that can print readable codes. Systems like SAE AS9132 grade codes on certain parameters to qualify for lasting scannability. For example, SAE AS9132 grades 2D data matrices on the following 

1. Quiet zone, the unmarked area that surrounds the symbol.

2. Symbol contrast, the reflective difference between the light and dark parts of a code.

3. Cell fill, the percentage of how an element is filling the ideal cell size.

4. Dot center offset, a dot’s position relative to the cell position.

5. Dot ovality, how much round elements are deviating from their circle.

6. Angle of distortion, the amount of deviation that occurs between rows and columns of the code. 

If any of these elements don’t meet system standards, supply chain issues can ensue. Fortunately, products from InkJet, Inc. can help you stay in compliance.

Find the Right Machine for Your Operation

For decades, inkjet printers have been used as go-to aerospace part marking machines. Using non-contact coding methods, inkjet printers are able to mark a wide range of materials, including both porous and non-porous substrates. The non-contact ink application enables inkjet printers to handle a variety of conventionally challenging surface types as well, including convex and concave areas.

Two types of inkjet printers are commonly used in the aerospace industry today: continuous inkjet (CIJ) printers and thermal inkjet (TIJ) printers. Both machines are capable of producing high-quality codes, but their mechanical properties make them ideal for different applications. 

Continuous inkjet printers, like the DuraCode Touchscreen and DuraCode Keyboard, offer:

• High-Speed Printing: CIJ printers create pressurized streams of ink that can code parts moving at over 1,000 feet per minute.

• Uninterrupted Operation: CIJ printers are capable of uninterrupted coding 24/7.

• Environmental Resistance: CIJ printers like those in the DuraCode series are built from modular stainless steel with IP55 designation. This fortifies them against environmental issues like dust particles and a certain degree of humidity.

• Simple Maintenance: CIJ printers are constructed with few moving parts making most problems minor and easy to solve.

Utilize the Ideal Ink Formula for Your Parts

Selecting the right printer isn’t the only important element to consider when marking parts—it’s also essential to use the right ink. Not all ink formulas are created equal as different surface textures vary in their ability to maintain code legibility. Fortunately, both CIJ and TIJ printers are compatible with a wide variety of inks allowing them to successfully mark diverse substrates.
