The application of the hottest aluminum profile in

The application of aluminum profile in TV appearance is only dazzling

aluminum, which has the advantages of light weight, easy processing, good corrosion resistance, and rich surface treatment, so that aluminum is considered to be the most economical and practical in many application fields. However, pure aluminum has low strength and is not suitable for use as a structural material, so adding alloy elements and using heat treatment to strengthen aluminum produces aluminum alloy

aluminum profile is designed and manufactured according to the required section of profile products. The heated aluminum alloy round cast rod is extruded from the mold by extruder, and then cut and processed. Aluminum profiles are often used in transportation, construction materials, household appliances and other industries

in recent years, due to the changes in the upstream screen resources of the TV industry, the previous design of TV appearance has been innovated, which has brought two changes: from the shell design to the integrated design of module structure and shell, and from plastic material to metal material. When it comes to metal materials, aluminum profiles are widely used in the middle frame, decorative parts, front shell and base of the current TV industry because of their many advantages, and have become the mainstream application form of metal aluminum alloy. Next, let's count the application of aluminum profile in the appearance of TV:

I. The Application of aluminum profile in the middle frame

at CES 2012, South Korea LG exhibited the world's first borderless TV lm9600, which uses a metal bent middle frame to attract the attention of a large number of visitors. Since then, LG has synchronously opened the whole screen resources of art3 and art5 series, which has also opened a new direction of appearance design in the television industry

art3's whole screen focuses on the concept of "ultra narrow frame", while art5's is a "borderless" whole screen. Both require the use of a metal middle frame to protect the screen body and cover the side screw holes. Through practice, I 3. Machining before heat treatment found that using aluminum profile forming and bending processing can form a metal middle frame with good strength, high precision and effective control of the gap with the screen, which meets our preset requirements

8100 series is Konka's first TV with art3 screen. The middle frame adopts aluminum profile four side bending process, plus light colored oxidation wire drawing treatment, which has a low-key luxury in line with public aesthetics. After listing, Konka has repeatedly achieved the best sales performance of high-end models

Konka 8300 series is the subsequent version of 8100 series, which is the second generation of art3 TV with ultra narrow frame. Through the unremitting efforts of Konka design team, we have developed a mirror plating level polishing process, and further upgraded the surface treatment of the aluminum profile middle frame. With such a dazzling appearance, it can become the designated TV model of Shenzhen Bao'an new airport

9500 series is Konka's latest art3 screen model in 2014. In the design of aluminum profile middle frame, the process of "step by step + double surface treatment" is used, which is visually layered to achieve the effect of compressing the thickness of the whole machine

II. Application of aluminum profiles in decorative parts

because the middle frame of ultra narrow/borderless TV is bent by aluminum profiles, if the decorative parts use the same metal materials, it can avoid the problems such as large assembly gap caused by injection molding decorative parts, so the material of the lower frame of TV also produces the transformation from plastic to aluminum profiles

Konka borderless TV 9000 series uses aluminum profile trim for the first time, which not only effectively protects and supports the borderless screen, but also perfectly connects with the side aluminum profile middle frame

Konka 8300 series has a mirror polished middle frame, and the decorative parts formed by aluminum profiles are also simple, low-key and meaningful. The designer used the delicate touch of the metal frosted shell of iPad for reference, and transplanted the process to the metal decorative parts of TV to make it warm and touchable

III. application of aluminum profile in the front shell

direction 1: aluminum profile four sided splicing front shell

in recent years, the birth of the module integrated machine has transformed the domestic TV brand manufacturers' procurement of upstream screen resources into only the core component - screen glass, so as to improve the proportion of self-developed components and obtain more benefits from wdw-e electronic universal experimental machine

the front shell of the module all-in-one machine is a structural part that is both an external part and a fixed screen glass. It is usually made of metal stamping parts. There are some problems, such as few changes in details, high mold cost, structural design limitations and so on. At this time, Konka 9800 series, which uses four sided aluminum profiles to splice the front shell, came into being

9800 series front shell adopts unique laser welding technology to control the splicing gap of four aluminum profiles below 0.1mm, combined with the frame highlight drilling and cutting process, highlighting the handicraft texture of high-end flagship models. It is worth mentioning that the front shells of this series with different sizes adopt a unified profile section shape and share a set of profile molds, so as to reduce mold investment and material management costs, and greatly improve the yield and production efficiency. In this way, the R & D and production costs can be greatly optimized, while ensuring the exquisite quality of the products, so that the products are in a dominant position in the market competition

direction 2: traceless bending front frame of aluminum profile

the industry continues to develop, technology continues to progress, and user experience continues to improve. Konka easy tvslim8800 series carries the user experience demand of "narrower and thinner", and uses the domestic original metal aluminum profile traceless bending process to create a dream model combining new technology and user experience

traceless bending process, that is, after the aluminum profile is formed and bent, the front and side of the frame are not bent, which has high precision and repeatability; It can be used for tensile, shrinkage, zigzag, shear and spalling test of various materials according to relevant national or international standards. The traceless bending process adopted by Yi tvslim8800 has gathered the sweat of the R & D team, and made the frame to the extreme 7.8mm and the thinnest part of the body 12.8mm. In addition, the assembly process of the front shell without trace bending is more advanced, and the labor cost and loss are lower than those in the past

IV. application of aluminum profile in the base

with the evolution of ultra narrow and ultra-thin TV, the base has abandoned the clumsy plastic shape in the past, and the light base with good support strength has become the highlight of TV design

in 2013, Sony took the lead in launching a small-size module integrated machine, equipped with a low-cost aluminum bending base, and optimized the matching of process and cost through ingenious design. In the follow-up, a number of large cross-section aluminum double foot bases have been launched, setting off a popular trend of new base materials

direction 1: aluminum profile bending base

can realize fully automated manufacturing

sonyw650a base is to bend the small section aluminum profile into the designed shape through the tooling, and the surface is simply sandblasted and oxidized, and then connected to the TV through the adapter bracket. This base is simple and generous in design and low in cost. It is a good application model in the industry

direction 2: the two leg base of large section aluminum profile

sonyw850b is also original. It uses large section aluminum profile to stretch, then cutting, grinding, local CNC and subsequent oxidation processing. The advantages are obvious: ① the adapter bracket is integrated with the base to save the assembly process and improve the production capacity; ② Small size, cost advantages; ③ It has better stability with large-size models
