Aluminum has the advantages of light weight, easy processing, good corrosion resistance and rich surface treatment, making aluminum the most economical and practical metal material in many applications. However, pure aluminum has low strength and is not suitable as a structural material. Therefore, alloy elements can be added thereto and heat treatment can be used to strengthen aluminum, and aluminum alloy is born.
The aluminum profile is designed and manufactured according to the required section of the profile product, and the heated aluminum alloy round cast bar is extruded from the die by an extruder, and then cut and post-processed. Aluminum profiles are often used in industries such as transportation, construction materials, and household appliances.
In recent years, due to changes in the upstream screen resources of the TV industry, the design of the TV appearance has been revolutionized, which has brought about two changes: from the shell design to the integrated design of the module structure and the shell, and the transition from plastic materials. Designed for metal materials. When it comes to metal materials, aluminum profiles are widely used in the middle frame, decorative parts, front shells and bases of the current TV industry because of their many advantages, becoming the mainstream metal aluminum alloy application form.
Here we will take a look at the appearance of the aluminum profile on the TV:
First, the use of aluminum profiles in the middle frame
At the 2012 CES show, LG exhibited the world's first borderless TV LM9600, which uses a metal folding frame to attract the attention of a large number of visitors. Since then, LG has simultaneously opened up the ART3, ART5 series of full-screen resources, and has also opened up a new direction in the TV industry design.
The ART3 full screen features the "ultra-narrow bezel" concept, and the ART5 is the "borderless" full screen. Both require a metal middle frame to protect the screen and cover the side screw holes. Through practice, we found that the aluminum frame is formed by bending and forming, which can form a metal middle frame with good strength, high precision and effective control and screen fit, which satisfies our preset requirements.
The 8100 series is the first one of Konka's ART3 screen TV. The middle frame is made of aluminum four-sided bending process, and the light-colored oxidized wire drawing process has a low-key luxury that conforms to the public aesthetic. After the listing, it has repeatedly created the best high-end model sales performance of Konka.
The Konka 8300 series is a follow-up version of the 8100 series, the second generation of ultra-narrow bezel ART3 TV. After the unremitting efforts of the Konka design team, the mirror plating level polishing process was developed to further upgrade the surface treatment of the aluminum frame. Such a dazzling appearance is nothing more than a designated TV set at the Shenzhen Baoan New Airport on the tall.
The 9500 series is the latest ART3 screen model from Konka in 2014. The design of the aluminum frame is based on the “step-by-step + double surface treatment” process, which is visually layered to achieve the effect of compressing the thickness of the whole machine.
Second, the use of aluminum profiles in decorative parts
Since the middle frame of the ultra-narrow/frameless TV is bent by the aluminum profile, if the same metal material is used for the decorative piece, the problem of large assembly gap caused by the injection molding decorative part can be avoided, and therefore the material of the lower frame of the TV is also produced from plastic to aluminum. The transformation of the profile transition.
For the first time, Konka's frameless TV 9000 series uses aluminum profiles to not only effectively protect and support the frameless screen, but also perfectly connect with the side aluminum frame.
In addition to the mirror-level polished middle frame, the Konka 8300 series is also simple and low-key, without losing its connotation. The designer borrowed the subtle touch of the Ipad metal matte back shell and transplanted the process onto the TV metal trim to make it warm and touchable.
Third, the use of aluminum profiles in the front shell
Direction 1: Aluminum profile four-sided splicing front shell
In recent years, the birth of the modular machine has enabled domestic TV brand manufacturers to transform the procurement of upstream screen resources into procurement of only the core component, screen glass, in order to increase the proportion of independent research and development components and obtain more profits.
The front shell of the modular machine adopts structural components that are both appearance parts and fixed screen glass. It is usually made of metal stamping parts, and has problems such as less details change, high mold cost, and structural design limitations. At this time, the Konka 9800 series with four-sided aluminum profiles splicing the front shell came into being.
The 9800 series front shell adopts unique laser welding technology to control the splicing gap of four aluminum profiles to less than 0.1mm, and combines the high-brightness drilling and cutting process to highlight the craft quality of the high-end flagship model. It is worth mentioning that the series of different sizes of the front shell adopts the uniform profile section shape and share a set of profile moulds to reduce the cost of mold input and material management, greatly improving the yield and production efficiency. In this way, R&D and production costs can be greatly optimized, while at the same time ensuring the superb quality of the products, the products are in an advantageous position in the market competition.
Direction 2: Aluminum profile without bending front frame
The industry continues to evolve, technology continues to advance, and user experience is constantly improving. Konka Yi TV slim8800 series carries the "narrower, thinner" user experience needs, using the domestic unique metal aluminum profile seamless bending process, creating a dream model that combines a new technology and user experience.
The non-marking bending process, that is, after the aluminum profile is bent, there is no bending gap between the front side and the side of the frame. Easy TV slim8800 uses the seamless bending process, the sweat of the R & D team, the frame is built to the extreme 7.8mm, the thinnest part of the fuselage 12.8mm. In addition, the front shell assembly process with no traces is more advanced, and the labor cost and loss are lower than before.
Fourth, the use of aluminum profiles in the base
With the evolution of the ultra-narrow ultra-thin TV, the base has abandoned the awkward shape of the plastic, and the base with light weight and strong support has become the crowning touch of TV design.
In 2013, SONY was the first to introduce a small-size modular machine with a low-cost aluminum profile bending base, which optimized the process and cost mix through clever design. In the follow-up, a number of large-section aluminum profiles and two-legged bases were launched, which set off a trend of new materials for the base.
Direction 1: Aluminum profile bending base
The SONY W650A base is designed to bend a small section of aluminum profile through the tool. The surface is simply sandblasted and oxidized, and then connected to the TV through the adapter bracket. This base is simple and cost-effective, and is a good example of application in the industry.
Direction 2: large section aluminum profile two-legged base
The SONY W850B's two-legged base is also ingenious. It is stretched with a large section of aluminum profile, then cut, sanded, partially CNC and subsequently oxidized. The advantages are obvious:
1 The adapter bracket is integrated with the base to save assembly process and increase productivity;
2 small size, cost advantage;
3 Better stability with large size models.
