IMT is the abbreviation for in Mold transfer, also known as insert Mold three-dimensional. The traditional IMT process arose in 2006, similar to IMR (In-mold Roller) process, at that time the process equivalent to IML (mold embedded Parts injection in-mold Label) process to remove the color of the carrier pet layer, the color layer left on the plastic parts, when the product radian do not do much (
can only do 2D), color is not rich enough, basically only silk screen and color layer, metal color is very few. After more than 10 years of development, now the IMT process can leave a 3D optical nano-decorative layer on the plastic surface, compared with the traditional IMR to increase the 3D optical texture and PVD color film layer, the radian is larger.
It realizes a three-dimensional, photo, gradient and r angle products such as decorative effects,
In the appearance of the product will provide designers with a great innovation and implementation platform.
The IMT process is a new process which is integrated and extended by IML technology and IMR technology.
Advantages of IMT Process
The IMT process uses a two-layer optical texture diaphragm, which produces a 3D optical effect from the layers.
In the production of 3D curved mobile phone back cover, there is no obvious difference between IMT injection molding process and the product appearance effect that can be achieved by composite sheet, which is mainly material cost and structure cost. The first is the material cost. In the manufacture of 3D curved mobile phone back cover, IMT injection molding process can be done at one time, while the composite plate will need to first the whole PVD and texture printing, and then through the hot bending, hardening, CNC and other processes, in the end to achieve the same effect.
In the post-fabrication process of composite sheet, there is a problem of safe side, which leads to waste of material, and the overall material cost is higher than that of IMT. Next is the overall structure cost of mobile phone. 3D curved phone back cover, composite plate and glass, the product structure of the mobile phone is purely decorative parts, the overall structure of the mobile phone pressure on the frame, which will lead to the selection of the frame more demanding, more complex structure.
The cost of the box and its structure have the inevitable connection: the structure of each more than one hole, then a number of processes, the cost increases.
IMT Injection Molding can do the hemming and the assembly structure with snap and other integrated back cover, reduce the complexity of the metal frame, thus greatly reducing the cost of the overall structure of the mobile phone. IMT brings together a variety of decorative technology advantages, the adoption of the IML process in the diaphragm production advantages, absorbing the advantages of IMR process injection mold transfer, combined with digital printing and offset printing effect and traditional screen printing process, make IMT technology applicability, widely used, make up the traditional appearance of decorative technology limitations, Meet the high-level innovation requirements of product appearance decoration. The IMT process achieves 3D stereoscopic effects and product stretching to meet the needs of more in-mold decorating processes.
Currently, IMT Technology in Japan and Germany is a temporary leader. In summary, the IMT process not only makes the cell phone components greatly reduced, making it resistant to corrosion and scratch, but also the appearance of more appreciative. This requires a good low-temperature formability (fluidity) of plastic raw materials for IMT processing, excellent chemical and impact resistance, excellent adhesion, and high flame resistance.
The high-performance PC 5010-IMT series materials are excellent in meeting the requirements of this process.
IMT Process Market Trends In the IMT process background, the back cover material can not be compared to the specific cost, but with the box into one to locate the price of the product.
At present, from the market actually reflects the results, according to the price from low to high general selection principle is: plastic metal frame, composite sheet metal frame, 2.5D glass metal frame, 3D glass (ceramic) metal frame, such as several forms. New IMT technology combined with the most popular 3D optical texture PVD decoration method, compared with the traditional composite plate color value higher, radian is larger. For example, the newly-listed Huawei 8 series is benefiting from the new development of IMT-specific materials, so that the thickness of the cover is controlled within 0.8mm, the frame materials using PC special fiber-reinforced materials, so that the overall fuselage both rigid and strong toughness, the overall fuselage is only 7.8mm, not only the feel mellow and comfortable,
and the composite plate process with the same brilliant effect, so that the entire body looks shiny. The current IMT process, based on a new process of 3D optical textured PVD, has become a double-layered 3D optical textured pvd.
Plastic metal frame determines the entire shell material price factor is the metal CNC processing amount, and the IMT process compared with the hot high-pressure composite plate last year, IMT is not only as a decorative parts, but can play part of the structure of the role, reduce the frame processing hours, so in the 5G era is quite competitive.
Help the CMF design to achieve the floor When we talk about the concept of CMF, we might as well make an extension of understanding-a successful product can not be separated from the ' beauty value, texture and expression ', as if a person of physical fitness-it should not only have external beauty, but also have a strong physique, and the corresponding way of life; it's like a good business-- It should not only have a beautiful and orderly environment, but also have a healthy and effective organization and management system, as well as maintain its sustainable development philosophy, Mission, values.
This is a systematic synthesis of the concept, is a cross-compound concept, is not a single partition concept. Based on the understanding of this concept, in 2012 on the joint listed company group Tatsu Mold and domestic elite China Dayang for the ' large deep cavity parts of the PC-based in-mold decorative materials and molding process ' to develop joint development, involving materials, processes, software and molds and other fields.
The project was successfully funded by the Guangdong Science and Technology Department and the Ministry of Education, and successfully passed the acceptance and achievement appraisal in 2015, which was at the domestic leading level. The birth of a successful product, need to design, process, materials, equipment, tooling, post-processing, such as the whole industry chain cooperation. Conversely, if we are fragmented, lack of communication synergy, it will be difficult for the market and consumers with a good experience of products.
This is a new concept of industrial ecology, in such an ecological, we are interdependent, symbiotic win. IMT Technology to regenerate plastic
