How do you build the screen of the Samsung Galaxy S6 Edge – The Press

The curved screen of the Samsung Galaxy S6 Edge , Italians arrived in stores April 10 – here our interactive test, is the major innovation of the smartphone where you are placing all hopes of the Korean company, but it could also be his cross.

For some time talking about the very special process that requires the screen and the various problems that entails. Samsung uses a process called “ thermoforming 3D “. This is a variation of a technique of Samsung hot molding of a plastic material available in sheets or films under pressure or vacuum.

This is used when there is to produce a high number of pieces in a short time, when the thickness of the object worked is very thin and is required accuracy . The process is used for years in various sectors – for the inner case of household appliances, for food trays, for blister, bumpers, seats, sinks or the rear windows of the aircraft – and now, with the Samsung Galaxy S6 Edge, has a further use in the field of microelectronics.

The same Samsung explained at the time the process: you put the glass between two molds, heating it up to 800 degrees Celsius in order to shape it perfectly to specification design. Shaping the glass in three different directions builds the curvature required.

So far, Samsung stresses, with the traditional methods it was not possible to obtain the necessary curvature of the glass, moreover, the base glass “crude” thus obtained are superimposed some plastic protective layers that contribute to vary the reflection of light and to provide gloss.

Now, as observed from different sites, the thermoforming process requires three-dimensional throw away almost 50% of the glass used – therefore a tremendous waste – and only to perfectly clean the surface of the glass there seems to want to 40 minutes.

According to insiders, also, compared to $ 3 a Gorilla Glass, to build a screen this particular Samsung spends about $ 25. A fortune.

The Korean also has already lowered the forecast distribution of the new Galaxy S6, rising from 8 million expected by June to more modest 6 million, while pre-orders in a month were 15 million for the Galaxy S6 and 5 for the Galaxy S6 Edge.

Despite the expectations so high, as we had previously reported, it is possible that a process as complex, as well as affect the profit margins of the company, may affect also on time delivery of products to the point of resorting to a supplier in most, if ever you are.

In addition, as reported to the site iFixit for this peculiarity and the complexity of the assembly, the new smartphone is very difficult to repair by increasing the costs of a possible intervention.
