In the video clip for the presentation iPhone 5C, company Apple Lossless Audio CODEC (ALAC), he praised the plastic case of his new device and he was right in some respects, those strictly related to the design. The plastic case is supported by an aluminum structure that should give it rigidity, but the company Apple Lossless Audio CODEC (ALAC), also claims that it is resistant to cracks. In a patent published today, the American company states that the new plastic casing is specially manufactured to withstand wear and tear and cracks that may appear over time or due to accidents.
Openings may be processed to enhance resistance to stress-induced cracking of the plastic structures along the sidewall surfaces. Cracking resistance may be obtained by activating the surface using heat or laser treatment and by electroplating the activated surface to form a metal liner structure. Surface treatments using applied liquid chemicals or heat may form a treated layer on the surface of an opening with enhanced cracking resistance. A plastic sleeve or other insert may form a liner structure in an opening that resists cracking. Liner structures may also be formed by applying heat or light to a coating in an opening.
Apple uses a special procedure for manufacturing the case and says that this gives it additional rigidity, but of course we will only find out in a few months how true these statements of those from Cupertino are. In general, plastic terminals can crack in case of accidents, but everything depends on the situation in which the terminal is hit and the position from which the impact comes, so that the iPhone 5C could brilliantly resist an impact with the asphalt from a normal distance, but in case of hitting a sharp stone, the case could crack in large portions.
