Aluminium - Material Analysis Aluminum Business Card

These cards are lightweight and thin aluminum business cards made of aluminum alloy. The extremely thin coating is easy to engrave, durable and versatile. For example, aluminum business cards can be used to make gift cards, vouchers or metal name tags.

For the left-handed shop, we are considering using it as a voucher card with an engraved EAN code so that the date, amount and validity can be read at the checkout terminal. These vouchers can be used several times and easily stowed away in the card case.

The size of aluminum business card is 8.6cm x 5.4cm (length x width). They are exactly the size of a credit card or business card. The surface of the business card is smooth and shiny.

Hints:
In this test we tried to limit the best engraving parameters to 3 ways.

1)
The first test was the machine-specified standard test with power variation. This took place at 300 DPI, raster engraving, 100% speed, no focus shift and various powers of 19%, 31%, 46%, 58%, 73% and 86%.
The result amazed us, because the machine changed the focus in the meantime and thus made the engraving unusable at 59%. Nevertheless, it turned out that higher performance also brings better results. Liked best and the contrast at 86%.

2)
In the second test, we varied the performance again because there was a dropout in the first. We varied the power in 10% increments. We left the resolution at 300 DPI and the speed at 100%. If you analyze the first 10 numbers with a magnifying glass, you can see that too little energy (10%) gives a bad result. After that, the energy variation hardly makes a difference at 300 DPI.

3)
In the next step, we varied the resolution and the performance.

100% performance and 3600 DPI took 259 seconds. The result was useless.

90% performance and 2400 DPI is also not a very good result.

80% at 1200 DPI brought a fairly decent result, which we then used for the other focus variations.

70% at 600 DPI
60% at 500 DPI
50% at 400 DPI
gave very similar results.

Then we varied the focus in -1, -0.5, 0.5 and -1 mm.
There were no clear differences here.
