IMD技术

IM D定义一:IMD解释:IMD的中文名称:模内装饰技术,亦称免涂装技术。

英文名称: In-Mold Decoration,IMD是目前国际风行的表面装饰技术,表面硬化透明薄膜,中间印刷图案层,背面注塑层,油IN MOLDING LABEL 墨中间,可使产品防止表面被刮花和耐摩擦,并可长期保持颜色的鲜明不易退色。

IMD的发展历程:传统的塑料加工技术已渐渐无法满足新时代的需求,轻、薄、短小的消费性电子产品及环保意识的抬头,IMD技术就是在这个基础上应运而生。

由於 (IMD) 之诸多优点适合於3 C、家电、LOGO铭板及汽车零件之塑料产品,特别是目前流行的手机外壳及各式仪表面板。

为此世界许多材料如德国Bayer、美国GE、日本和韩国正投入大量人力和材力在研发适合于该工艺的新型材料,每一年都有涌现出大量功能薄膜和油墨材料。

(IMD)模内装饰是一种相对新的自动化生产工艺,与传统工艺相比(IMD)能减化生产步骤和减少拆件组成部件,因此能快速生产节省时间和成本,同时还具有提高质量,增加图像的复杂性和提高产品耐久性优点应用在产品外观上,(IMD)是目前最有效率的方法,它是在薄膜表面上施以印刷、高压成型、冲切,最後与塑料结合成型,免除二次作业程序及其人力工时,尤其一般在需背光、多曲面、仿金属、发线处理、逻辑光纹、肋骨干涉...等印刷喷漆制程无法处理的时候,更是使用IMD制程的时机。

(IMD) 模内装饰可以取代许多传统的制程,如热转印、喷涂、印刷、电镀等外观装饰方法。

尤其是需要多种色彩图像、背光等相关产品。

当然在这里要特别注明:并非所有塑胶表面装饰都能用IMD工艺所取代,IM D现在还存在材料技术瓶颈(如硬度与拉伸的反比关系,定位精度,异形与凸点间距,把模斜度等)具体产品要提供3D图档让专业工程师进行分析IMD的分类与相互特点:IMD包含IML,IMF,IMRIML:(无拉伸,曲面小,用于2D产品);IMF:IN MOLDING FILM (适合高拉伸产品,3D 产品);IMR:IN MOLDING ROLLER (产品表面薄膜去掉,只留下油墨在产品表面。

IMD技术概要

IMD技术概要
IMD(In Mold Decoration)技术,即注塑成型表面装饰技术,是目前风行的表面装饰技术,主要用在手机及一些电器面板、保护显示屏的透明镜片、汽车仪器仪表的表盘、洗衣机面板整饰等,并已发展到装饰大型机壳,如汽车的外壳装潢等方面。
由于采用IMD技术,不仅装饰效果美观,而且与其他制造方法相比,使用寿命长,且防尘防潮性好,得到了用户的睐。
3)注塑模结构、型腔与成型模形状具有一致性;
4)模腔内的表面质量和光洁度高;
5)合理设计注塑模浇注口的位置、数量、大小、形状和注塑料的流动方向及注塑模的升降温系统,确保塑料浇注过程顺畅,减少注塑温度对IMD网印油墨的影响,提高注塑料和油墨及基材的结合牢度。
二.PC、PET透明片材背面网印专用IMD油墨
3)网印镜面油墨
采用帝国31000和9100、8100镜面油墨;100目/厘米 PET丝网;耐溶剂型感光膜片;胶刮硬度HS65~70;回墨刀刃口为圆角型,回墨时刮速略低。干燥:80℃,干燥后可获得较好的镜面效果。镜面油墨彻底干燥后,在其表面罩印黏合剂会使注塑后的镜面效果更好。
4)网印、注塑过程注意事项
图文表面网印水性黏合剂的工艺。但事实上,在溶剂油墨中,也需要网印水性黏合剂,镜面油墨属溶剂型油墨,又不能用溶剂墨保护,所以在溶剂墨的IMD技术中,为了防止IMD镜面油墨脱落、分层溶解、氧化,保护镜面油墨只能选用对镜面效果没有影响,不会破坏涂层的水性黏合剂。二是若注塑料为ABS、ABS+PC或PS,由于这些材料与油墨的黏合性欠佳,网印油墨后,再印水性黏合剂,能提高墨层与基材的结合力,同时,具有柔软性和成型性好的特点,减少分层开裂现象的发生。
我国在IMD技术的应用方面起步较晚,到2001年下半年少数企业才具有一定的规模,所以从目前国内和国外IMD技术的应用情况看,这项技术在未来的数年里会有非常广阔的发展前景!

IMD工艺分类
IMD是一个笼统的称呼,实际上IMD分为IMR、IML、IMF。
IMR (In-Mold Roller) ——模内转印,日本称热转写或热转印。是将 已印刷好图案的膜片置入模具内,通过送箔器自动定位,然后将树脂 注入模具内与膜片结合,使原来印刷在膜片上的图案与膜片分离而转 移到跟成型树脂成一体的一种成型方法,膜片在生产过程中仅起到一 个载体的作用,最终不与产品成一体。【重点在于胶料上的离型层, PET FILM→印离型剂→印刷油墨→印接着剂→ 内塑料射出→油墨与 塑接着→开模后胶料会自动从油墨离型。它的片材定做周期比较长, 模具费用比较高,技术不输出,只有日方有。】

IMD射出成型注意要點
g.射出条件在IMD工艺中可变性较少,所 以建议选择控制精度较高的注塑机;塑 料的物性也要求一致性很好。
h. 因FILM热胀冷缩的特性,其模具溫度不 能太高成型,所以建议使用模溫机。
I i. 因为內置薄膜,越厚的地方越容易产生 缩水,所以缩水的解决办法不能用传统 的保压、过压的方法来处理,只能通过 减料、掏空的方法来处理。

七)IMD射出成型常出現的問 題及解決方法
1)IMD注塑中花样油墨被冲散(洗)掉的,主要 原因如下: ●IMD油墨干燥不透,存在残留溶剂,且还 会产生气泡,注塑时油墨扩散并与片材附着 力下降等; ●IMD银色墨需要更长些时间烘干; ●IMD片材厚度的影响,油墨被冲散的面积 隨片材厚度的增加而加大; ●与入浇口设计的结构、形狀以及分布是否 合理有关;

imd技术(IMD技术)Introduction of IMD TechnologyIMD definitionIMD interpretation: IMD Name: Chinese mold decoration technology, IMD technology is the international popularity of the surface decoration, surface hardening, transparent film, intermediate printing pattern layer, middle layer on the back of the injection, ink, enable the product to prevent surface scratches and abrasion, and can maintain long-term bright color is not easy to fadeName: English ("a" a ction Moulding Decoration,In-Mould-Decoration)"A" a ction n. injection, injectionMoulding n. molding, castingDecoration n. decoration, decorationsTraditional plastic processing (spraying, printing, electroplating, heat transfer and other decorative methods) technology has gradually unable to meet the needs of the new era. IMD technology is based on this process came into being is the best, set decoration performance in a function of injection molded parts, graphic color in the injection molding of a molding, reduce subsequent processing procedure of injection molding, in addition IMD stereo shaping increased design freedom, graphics, color in the plastic interlayer,abrasion resistance and corrosion, and color printing pattern change at any time without changing the mold. IMD technology is mainly used in: home appliances, communication products, electronic products, instrumentation, medical equipment, toys, cosmetics, automobile accessories, digital products, etc.. Case study: due to the advantages of (IMD), it is suitable for 3C, household appliances, LOGO nameplate and automotive parts of plastic products, especially the popular mobile phone shell and all kinds of instrument panel. The world's advanced manufacturers such as Germany Bayer, the United States GE, are in full development of this process.Brief introduction to IMD Technology Series Forum (1) -IMD TechnologyIn the past two years, IMD technology has been widely used in consumer electronics and automotive interior, a bit hot feeling. Here we do some of the introduction of the technology.The concept and history of IMDIMD is the abbreviation of English Decoration (In-mold). From the literal meaning of English, the method and purpose of this technology can be well understood. "In-mold" is what is put in the mold inside; "Decoration" is the decoration meaning, so this technique is to put what in the mold, the purpose is to make the product good. This technology actually appears very early last century, in 70s and 80s we have been in use, but because some of the obstacles to cost and material technology, of course, the key is the market demand is not so high, so there is no widely used.The development and application of IMD in ChinaIn recent years, consumer electronics and automotive market competition has intensified, in order to make their products can be different from the competition, to seize the customer in the first time, each manufacturer in the product appearance color spare neither labor nor money. It is in this market situation, this technology is getting more and more attention. In China, this technology was first used in household appliances, such as washing machines, microwave ovens, air conditioners and other panels. Later, the mobile phone manufacturers such as Motorola the first application of this technology in the A mobile phone flip cover, many domestic manufacturers to follow the trend, so the emergence of some IMD suppliers.Two kinds of IMD TechnologyBefore we go into this technology, we need to clarify some of the conceptual properties. The IMD we're talking about here, more people in the country call it IML, which is the final product, with the outermost layer of PC or PET film. There is another kind of IMD technology, which represents the Japanese Nissha and the German Kurz, and their IMD technology is actually called the thermal transfer technology. That is, first print the pattern on the PET film carrier, and then in the injection molding, the printed film on the surface of the transfer to the injection molded surface, and then peel off the film, and ultimately the outermost layer of the product is a layer of ink.The differences between the two IMD technologies are reflected in the following aspects:1. different processesThe IMD we are going to pass through four links: film printing molding punching cutting injection molding (sometimes without molding); heat transfer printing through film printing injection two links.TwoThe abrasion resistance of the finished products is differentThe wear resistance of IMD finished products is much higher than that of thermal transfer printing products. IMD the outer layer of the product is PC or PET film, the ink is sandwiched between the film and plastic particles, so the color is difficult to wear, the pattern will be the maximum protection. However, the outer layer of the finished product made by thermal transfer technology is only a hardened layer. Although the hardness of the hardened layer is up to 2H, the actual wear resistance is not good. A few years ago, Nokia low price mobile phone lens made a lot of this process, less than half a year, the color has been worn off.3. processes have different capabilitiesIMD can be used as a product range to transfer a lot of specific heat. IMD not only can be made into a large stretch or 3 dimensional parts, but also can be flat or simple camberedsurface products. And heat transfer technology basically can only be flat or simple arc products, such as mobile phone lens. Where is the reason? Heat transfer is in the injection molding, the film (unformed) into the mold, and if it is verythree-dimensional parts, film and plastic can not fit very well.4. the cost structure is differentFilm heat transfer is only Nissha a, and between the products can not be replaced, that is to say you do different projects to do, have to prepare the specific inventory; Nissha there is no inventory, it is difficult to ensure delivery, so the cost is difficult to reduce. And for IMD technology, manufacturers directly buy transparent clean film, so there will not be dead inventory. According to the two processes are very professional manufacturers to compare, the cost of heat transfer parts is higher than the IMD technology products 20%.5. different business modelsIn the process of thermal transfer, Nissha provides membrane die, so it has the right to pricing, the injection molding factory is only its currency counting machine. And in IMD, the injection molding factory has its own pricing power, which is completely different from the heat transfer process.IMD Technology Series Forum (2) -IMD material selection:Summing up the above two kinds of IMD technology, we can see that the Nissha IMD technology has the advantage of easy process,but a long period of high prices, the cost of IMD is the low, high profit, but you need to explore and study the long time. So before you get into this field, you think about which one to choose. The IMD technology we analyzed below does not refer to the thermal transfer technology of Nissha, but refers to the technology of a PC/PET film on the surface of the final product.IMD Technology Series Forum (2) -IMD material selectionIMD technology will be designed to three kinds of materials: film, ink, plastic particles, we will discuss IMD requirements for these materials one by one.FilmThere are several kinds of films currently in use:1. PC thin film: the most important IMD film materialCharacteristic:High heat resistance and vitreous temperature Tg140CGood tensile properties. The ductility of PC is very good, and the ductility is 160%Good processability. Because it is amorphous material, so the forming temperature range is very large, so the film forming temperature range is very wide, from cold forming to thermoforming 170C can; the molding temperature here refers to the temperature of the film;Wide range of products. The surface has frosted, fine sand, hardened, anti fog and so on, different types can be selected;The hardness is up to 1H. Why don't we love original PC film is PC film surface hardening by up to 1H, the GE company has a new film surface of a DMX can reach 1H, and the tensile performance is very good, to solve the previous tensile properties and surface hardening of the contradictory problemAt present, the most popular products for customers are GE series OQ hardened films, the latest superhard forming film DMXIt has a wide range of applications: mobile phones, cars, consumer electronics and so on.2. PET thin film:CharacteristicHigh surface hardness. The PET film can reach 2H after hardening;Good chemical resistance.Poor formability. PET film can not be bigger stretch parts, can only be flat or simple arc products.Deformation after molding. PET is a crystalline material,There is no so-called vitreous temperature, either solid, orlike water, so thermoforming can only be in solid state, so PET molding can only be forced molding. The result is that the PET film is very resilient after forming, resulting in a very serious deformation after the product is finished. All manufacturers who use PET film to process IMD parts are confronted with this problem at present. But the problem is insurmountable, in terms of the material itself;The current application areas are mainly in home appliances and mobile phone lenses. Such as air conditioning electric cooker control panel, mobile phone lens is flat, so you can also film to do.3. ABS thin filmCharacteristicABS film is mainly used in automotive interior parts, some professional film factory on the ABS film printed on walnut or metal film, plus hardened layer. The manufacturer is represented by Avery in the United states.printing inkBecause of its particularity, IMD technology has specific requirements for printing ink:Temperature resistance. Because IMD process is after printing and injection, so the ink must be resistant to more than 200C, otherwise it will be washed away by injection of material flow;Ductility. There are hot forming in injection molding before the ink of course together with the film tension, if the ink is malleable after hot forming, the ink may leak, cracks etc..At present, there are many vendors who claim to be able to provide IMD ink in the market, but in fact, there are not many good ones. It looks like two people:Type UV Decomold series with Sunchemical;Solvent type N2K and HTR series with ProellAs you all know, solvent type ink drying time is much slower than UV type, and requires a long drying oven or oven, and UV type does not need. From the point of view of yield, UV is better.Plastic particlesThe choice of plastic particles mainly depends on the requirements of OEM manufacturers for the performance of parts. At present, PC, PC alloy, ABS and PMMA are used, and the advantage of PC is good impact resistance, and PC is mostly in the automotive and mobile phones. PMMA is low injection temperature, light transmittance and surface hardness are relatively high, so in some lenses products used more.Is worth mentioning is that the current development of PC alloy technology soon, some of the PC alloy retains the strength of PC and reduce the injection temperature of the liquidity, such as the temperature of the PC/Polyester alloy Xylex X8303 GE,a new injection of about 240 260C, but also better than the average flow of PC high impact resistance at present, GE company has been in the promotion, you can go to "a bit.IMD Technology Forum Series (3) -IMD process and equipment requirementsThe IMD process consists of the following four steps:1. printing. Print on transparent film, print the desired pattern of the customer. Of course, the printing needs screen printing machine, the condition of good buy, the condition of general buy general, in short because of their own conditions vary.Printing is very important for IMD. The quality of printing and the choice of ink will affect the other processes. For example, your ink did not choose right, drying is not enough, then the latter process is very easy to produce ink phenomenon.Basically ink selection must choose IMD special ink, if the solvent based ink, drying must be sufficient and the mesh screen is greater than 300.2. forming. Injection molding industry, many people call molding process. What we call molding here is not the idea of printing a thin film into the shape of a customer's needs. You need a cell phone shell to form the shape of a cell phone shell, you need a laptop, and it's made into a laptop shape.When forming, the film and ink are stretched to a certainextent.Molding needs molding machine. The difference between high and low grades is very large: the simplest low grade thermoforming machine is the hydraulic press, which is very simple. Some high-end vacuum or high pressure molding machine, mold mold or mold only, heating thin film after high pressure gas flushing or smoke, there are the combination of the two.High pressure or vacuum is more expensive, equipment also has a single station or two stations, also lead to different prices.The film forming method is specially introduced below.3. punch cutting. After a good film forming shell, there must be some parts are not needed, so the part cut off unnecessary. This part is also a very important part of IMD, some of the three-dimensional shape is not good cut, cutting precision, knife shape has a lot of experience inside. Especially some products with high requirements for hemming.4. injection moldingPlastic injection is the last step. The adjustment of the process, the structure of the mold and the choice of the plastic injection have great influence on the final yield. There is no general rule here, because the shape, pattern and shape of the product are quite different, and they can only rely on experience. Generally speaking, the gate of the mold should not be a point gate as far as possible, and the plastic should be made of low viscosity and high flowing material.IMD injection is not too high for the equipment, ordinary injection molding machine can be. But when doing a lot of products, vertical injection molding machines bring a lot of convenience, such as making holes free products, the film can be placed directly on the mold without the need to do other positioning facilities.In addition to that can put two sets of mold a mold equipment, so you can put a set of injection molding and shell two movements do not interfere with each other, shorten the injection time.IMD Technology Forum Series (4) -IMD product designProduct design of IMDIMD has some special requirements for product design because it involves printing patterns, thermoforming, etc.:1. angle is greater than the thickness of the film; that is to say, the corner of the product can not be 90 degrees, the greater the corner, the more favorable for forming;2. in the vicinity of the gate, it is best not to put complex patterns to avoid ink stamping;3. in a larger stretch to avoid putting patterns, the author in the process of practice found that many people like to say that this is not to the pattern design is limited? In fact, otherwise, stretched larger places generally appear in the side of the product, what kind of special design must be placed onthe side of the pattern?4. if you want to have a large stretch of the pattern, it is best to always imitate some software.The above requirements are not harsh. So IMD for product design should say is only good, no harm, it brings designers great freedom, that is to say, with IMD can realize many spray paint is difficult to achieve effect.In addition to membrane material development at present is also change rapidly, leather textured film, wove film, metal texture effect of the film, in short, IMD is the most popular of the industrial designerIMD Technology Series Forum (5) -IMD applicable occasionsThe most suitable occasion for IMD applicationA lot of people tell me they want to use IMD, but it's too expensive to use, and there's a lot of misunderstanding in it.First of all, IMD is applied to customers with high appearance requirements. If your customers think that the appearance is insignificant, it is not necessary to use this technology; IMD application is best to have a pattern or text can reflect the advantages of printing place.Secondly, the advantage of IMD is that when you have a variety of product designs, such as a product has a variety of appearance, in such circumstances, IMD may reduce the cost willbe reduced. Just imagine, a ten shell of the mobile phone, you may need to order ten kinds of plastic particles of different colors, ten different colors of paint, but IMD does not need, because of its color is reflected by printing a color, as long as the particle is good. As a result, the price of plastic particles and inventory and waste costs can be reduced.Again, using some special method can even use the benefits of IMD, but also reduce costs. We know that the cost of IMD is sometimes higher than that in thermoforming. Is there any way to get rid of this step? As long as the film does not wrap the angle, the film does not need to be preformed,Just put the stamping cut film into the mold directly injection, just like that, the cost will soon be much lower, but also use the benefits of IMD.Application fields of IMD / IML:Home appliance industry: electric cookers, washing machines, microwave ovens, air conditioners, refrigerators and other decorative panels control;Electronic industry: MP3, MP4, VCD, DVD, calculator, electronic notepad, digital camera and other shell and signs;Automotive Industry: dashboard, air conditioning panel, interior trim, light housing, signs and so on;Computer industry: keyboard, mouse, face shell;Communications: mobile phone keys, mobile phone lens, mobile phone and fixed phone, PHS color display panel, window lens;Other industries: medical equipment, cosmetics boxes, decorative boxes, toys, sports and entertainment, leisure products and so on.。

IMD射出成型注意要點
g.射出条件在IMD工艺中可变性较少,所 以建议选择控制精度较高的注塑机;塑 料的物性也要求一致性很好。
h. 因FILM热胀冷缩的特性,其模具溫度不 能太高成型,所以建议使用模溫机。
I i. 因为內置薄膜,越厚的地方越容易产生 缩水,所以缩水的解决办法不能用传统 的保压、过压的方法来处理,只能通过 减料、掏空的方法来处理。
a. 流道设计愈短愈好,采用热流道最佳. b. 浇口面积可加大或采用多点浇口.

IMD射出成型注意要點:
c. 塑料选择:流动性愈高愈好,射出温度愈 低愈好.
d. 在浇口位置可加防止冲墨的油墨,如宝龙公 司(PROELL)的.
e. IMD注塑模的型腔与成型模形状要保持 一致性;
f. 射料交会点尽量不要选择在拉伸最高的位 置(大多時候在四角的位置,因此处较薄, 热胀冷缩更为严重,会出现皱折。
IMD技术简介
IMD(In-Mould-Decoration)即模内装饰技 术,它是指把一个丝印有图案的FILM放 到塑料模具里进行直接注塑而成的塑料 装饰工艺技术 。此FLIM大致可分为三层, 基材(一般为PET、PC片材), INK(油 墨),耐磨材料(多为一种特殊的胶)。当 注塑完成后,film和塑胶融为一体,耐磨 材料在最外面。

二)IMD特点
一般来讲用IMD有两个背景原因, 1, 有些效果用注塑实在难以模拟,比如胡桃 木的汽车仪表板(汽车配件模具上的)。 2,在小片零件上集成几种效果很难,比如 MOTO V60模具的前三角片, 集中了电镀,透 明,丝网印,但本身又要求精致,试想用真实 电镀,透明片分别注塑再拼接基本很困难。 还有一种方法实现就是在模具阶段做零件表面 皮纹(TEXTURE)时件外表面光滑,内表面用 粗糙纹路,但对模具有要求,因为粗纹理拔模 角大。
水性黏合剂应加硬化剂,但加后应在2h内用完 ●在PC上,用宝龙网印L48591镜面油墨时,应
