Mr. He of Huizhou Deyouwei Electronic Materials Co., Ltd. brought you a wonderful sharing of UV transfer and composite plate high pressure forming process. Mr. He introduced that UV transfer is a key process for composite panels or 3D glass foils, which directly affects the rendering of optical textures.
Deyouwei Electronic Materials is dedicated to the development of UV transfer technology, and has developed a special UV glue to meet the large demand for composite phone back cover. Deyouwei has been developing UV transfer adhesives since 2008. It has more than 10 years of experience in UV adhesive development and its products have passed rigorous testing.
Quanda Plastic Electronics Co., Ltd. first introduced the difference comparison between the three processes of IMR/IML/IMT, and then focused on the development and application of the Qantas IMT process on the back cover of mobile phones. General Manager Cai introduced that the traditional IMT process has this name in China in 2006. In fact, it is similar to the IMR process written in Japan. At that time, the process was equivalent to the IML process to remove the color carrier PET layer, leaving the color layer on the plastic part. The curvature of the product is not large, and the value is not rich enough (basically only silk screen, color layer, metal color are rare). The new IMT process combines the most popular 3D optical texture + PVD decoration method with a higher color value and greater curvature than the traditional one.
MT process is long, and each link needs to work closely to achieve high yield requirements. The Gundam IMT process is as follows:

Dongguan Xinqiaolian Composite Material Technology Co., Ltd. was founded in 2007. In December 2017, Dongguan Xinqiaolian Composite Materials Technology Co., Ltd. (hereinafter referred to as: Xinqiaolian Composite Materials Technology) was reorganized and established with a registered capital of RMB 5 million. The company focuses on the field of high-pressure molding of composite sheets.
Zhiyu is committed to customizing new equipment for the AFHC process, providing solutions for new processes and accelerating user mass production. Zhiyu Company provides customers with complete solutions such as processing and manufacturing and technology transfer. Today, Zhiyu Xiong always brings you a wonderful sharing of AFHC technology.
The AFHC process is an anti-fingerprint + hardened coating, which is the key process for composite panels and IMT mobile phone back covers.
By optimizing the process, Zhiyu adopts the AFC process of 3D spraying to make the hot-bending board process such as 3D glass completely reduce the product cost; in the process of ink technology development, it has the possibility of directly adopting ink instead of texture + PVD process.
With the rapid development of IMT mobile phone back cover technology, various raw material manufacturers have strengthened the development of special materials for IMT injection mobile phone back cover. Today, Mr. Yang, a new material of China Plastics, shared with us the special materials of China Plastics IMT. This special material has excellent performance indicators and effectively promotes the improvement of IMT process yield in the industry.
The performance indicators of China Plastic IMT special materials are as follows:
1) IMT injection molding, drop weight test after spraying, 200g/1m falling ball test: standard 1 time, measured falling ball 5 times without cracking;
2) IMT injection, spray high temperature and high humidity (65 ° C, 95% RH, 48H), thermal shock (-40 ° C, +70 ° C, 48 H), the sheet does not fall off, deformation, cracking
UV hardening is an important process in the manufacture of composite sheets or IMT back covers. The UV hardening layer is the outermost layer of the back cover of the mobile phone, which is directly in contact with the consumer. The hardness and wear resistance of the UV layer directly affect the durability of the back cover. The UV layer is not hard enough or hard enough but the adhesion is insufficient, which may cause the UV coating to detach.
Jieshida UA-1117 nano-modified high wear-resistant, anti-fingerprint UV resin is dedicated to solving the problem of UV coating on the board. UA-1117 is a high-functionality UV-reactive resin containing nano-particle modification. The UV-curable coating film based on it has very high surface hardness and excellent steel wool abrasion resistance. It is recommended for high hardness. Highly wear resistant PET, PC, PMMA hardened.
Mr. Hu shared with you the advantages of IMT process that brought together a variety of decorative processes, adopted the advantages of IML process in FILM, and absorbed the advantages of IMR process injection into in-mold transfer. The emergence of IMT process will replace the current industry spray. Oil, UV varnish, electroplating, vacuum color plating, silk screen printing, pad printing and transfer printing, etc., will drive the innovation of the product appearance industry.
IMT technology is more complicated than traditional IML in the process flow, and there are more processes in the latter stage. In the current low yield, the industry needs to increase the throughput of the process by strengthening the automated production, further reducing the product cost for large-scale application. Lichao Precision has developed research and development on IMT production equipment, and has introduced a variety of equipment and can cooperate with robots to adapt to IMT automation production.
In the next few years, the proportion of plastic mobile phone casings will account for more than 50%. 5G and wireless charging environment + cost control, plastic materials are preferred, and the total demand for plastic products in the future will be more than 3.5. A huge market capacity of more than 100 million pieces!
At present, there is a lack of supplier resources. The 3D composite sheet metal technology mobile phone back cover is currently in short supply and widely used. The market has two major business opportunities:
1) Continue to drive the development of related equipment manufacturers, such as orders for equipment such as UV transfer machines, screen printing machines, high-pressure molding machines, etc.;
2) Pulling the development of related raw material manufacturers, such as professional ink, UV glue, PMMA/PC sheet, UV shower and hard liquid, optical coating material manufacturers continue to benefit.
In order to cope with the insufficient capacity of the composite sheet process back cover, Zhenyus production workshop will be more than doubled and will be in the process of repairing and debugging. Zhenyu actively participates in the process improvement of composite sheets, such as the use of color dyeing process, instead of expensive coating processing; and the introduction of roll-to-roll automatic UV transfer and roll-to-roll plating processing, further reducing manufacturing costs and providing product quality.

It has accumulated rich industrialization experience in the surface hardening of PMMA/PC composite board. From hardening liquid to coating line, Huiwanchuan Company Independent research and development.
General Zhao introduced that since the sheet is vertically sprayed, the coating thickness of the product is unevenly distributed from top to bottom. The production process requires timely and accurate detection of the film thickness, so that the production parameters of the coating are in accordance with the film thickness requirements. The process flow of Huiwanchuan coating is as follows:
Mr. Yao shared with you the samples of the back cover of the IMT/IML gradient coating, which showed a variety of different coating effects. Incorporating the physical copy, Yao introduced to you that the basic principle of the cool optical texture currently applied to composite panels or IMT processes is based on optical interference. When light passes through a layered medium such as an optical film, reflected light and transmitted light from different interfaces generate interference of light in the direction of incidence and reflection of light. By utilizing this interference phenomenon, the interference of the light is artificially controlled by changing characteristics such as the material and its thickness, and the redistribution of the light energy is realized as needed to cause a continuously changing spectral color upon visual observation. Using this principle, it is possible to design a corresponding film system for the optical texture effects of various mobile phone back covers.

Mr. Yao believes that under the trend of composite boards and IMT becoming increasingly popular, coating is becoming one of the factors limiting production capacity, and the winding plating scheme is an excellent coating solution for mass production and production capacity. According to reports, Zhenhua winding plating equipment can be stabilized at 1000m2/day, with uniformity and repeatability. After continuous design, the continuous coating can reach 3000m2/day. In the future, it will be widely used in IMT and IML mode, and the cost will drop sharply after the combination of the roller type 3D micro-pattern mold and the winding type continuous screen printing machine.
