Under eloxal printing on aluminium
Digital printing by Benz.
Unrestricted creativity through modern digital printing
Comparison of Finishing and Marking Methods
Printed aluminium in photo quality!
In short: Everything you print on paper on your inkjet printer at home, we print on aluminium. Thanks to our modern digital printing technology, we can guarantee the highest quality and achieve exact printing results.
Every colour can be reproduced, even colour gradients are possible in digital printing. Due to the special production process we do not only apply the colour to the material, but also work your motif into the aluminium. We are talking about a subeloxal pressure.
We print on aluminium in sub-eloxal printing
. . . for a consistent result in individual production or large series! Due to the sub-eloxal printing we achieve a higher resistance to friction or even solvents and cleaning agents than with normal printing. Due to the low set-up costs, this process is suitable for individual production, but series are also possible.
We would also be pleased to inform you personally about our extensive range of services and the advantages of the various production processes.
Frequently Asked Questions (FAQ)
1. What is sub-anodized printing and what advantages does it offer?
Sub-anodized printing is a process where color pigments are applied directly into the unsealed pore structure of an anodized aluminium layer and then permanently sealed. This makes the print extremely scratch-resistant, chemical-resistant, solvent-proof, and weather-resistant.
2. What materials are used for front panel manufacturing at Benz Alutec?
Benz Alutec primarily manufactures front panels from high-grade aluminium, stainless steel, and specialized plastics. Depending on requirements, anodized, powder-coated, or raw surfaces are processed.
3. Why is sub-anodized printing superior to standard screen or digital printing on aluminium?
In sub-anodized printing, the ink is embedded safely beneath a transparent anodized oxide layer, whereas standard printing sits on top of the surface. As a result, sub-anodized prints cannot peel off and resist aggressive cleaning agents and UV radiation.
4. What is the difference between industrial engraving and printing?
An industrial engraving creates recessed lettering or logos directly into the material via CNC milling, whereas printing is a surface or sub-anodized ink application. Engravings remain readable permanently even under severe mechanical wear.
5. Does Benz Alutec manufacture custom CNC milled aluminium parts?
Yes, Benz Alutec manufactures custom CNC milled aluminium components according to client specifications and CAD data. Both prototypes and small to large production runs are fabricated with tight tolerances.
6. Are self-adhesive foil labels from Benz Alutec suitable for outdoor use?
Yes, foil labels are equipped with high-performance adhesives (e.g., 3M) and are completely UV- and weather-resistant. They are ideal as machine rating plates, warning notices, and outdoor labels.
7. What does sub-anodized printing mean in industrial applications?
Sub-anodized printing refers to the process of sealing ink inside aluminium pores, providing maximum resistance against abrasion, harsh chemicals, and extreme temperatures.
8. Which file formats are required for custom front panel production?
Vector file formats such as DXF, DWG, STEP, AI, or print-ready PDFs are required for contours and artwork data. These files are directly processed for CNC milling and printing units.
9. Does Benz Alutec produce small batches and single prototypes?
Yes, Benz Alutec offers flexible manufacturing ranging from individual prototypes to high-volume production series. Modern CNC and digital printing tech ensure cost-efficient small batches.
10. Which industries benefit most from sub-anodized aluminium printing?
Sub-anodized printing is widely used in mechanical engineering, medical technology, aerospace, electronics, and automotive industries. It is required wherever labels must be sterilizable, oil-proof, or weather-resistant.
11. What color options and print resolutions are available?
Sub-anodized printing supports multi-color company logos, photorealistic images, fine scales, and custom spot colors within the CMYK spectrum. All colors remain lightfast and protected against solvents.
12. How are front panels and rating plates mounted?
Mounting options include precision CNC drilled holes, countersinks, threaded studs, or heavy-duty self-adhesive backing. Selection depends on installation conditions and mechanical stress.
13. What are the advantages of aluminium over stainless steel for front panels?
Aluminium is significantly lighter, easier to machine into complex CNC shapes, and allows colorful sub-anodized printing alongside corrosion resistance. Stainless steel offers higher chemical resistance.
14. How durable are industrial engravings on aluminium components?
Industrial engravings offer virtually unlimited durability because markings are cut deep into the metal structure. Text remains clear and readable even under severe mechanical friction or dirt exposure.
15. How does the inquiry and order delivery process work at Benz Alutec?
Clients submit CAD or graphic files online, receive a tailored quote, and production is handled directly in Germany with fast turnaround times. Domestic and international orders are supported.
